          <p>
            <var>TGridState</var> is an enumerated type with values that reflect the state in a grid control. TGridState values represent actions performed using a grid control, rather the display state for rows, columns, and/or cells.
          </p>
          <p>
            TCustomGrid maintains an internal TGridState member used to track the state for the grid control. Methods in TCustomGrid cause the value in the member to be read or updated to reflect the request and/or completion of an action in the grid control.
          </p>
          <p>
            Use the TCustomGrid.Options and TCustomGrid.Options2 properties to determine if specific features or behaviors are enabled for a grid control.

          </p>
          <p>
            ExchangeColumn calls HasIndex to ensure that both values within the range allowed (0..Count-1). An exception is raised if either value is not in the required range for the column collection.
          </p>
          <p>
            The order for the index positions is not significant; the column with the larger of the two index values is updated first. This prevents an exception from being raised when the column positions are swapped.
          </p>
          <p>
            ExchangeColumn swaps the values for the Index properties for the corresponding TGridColumn instances in Items. The Grid control associated with the collection is notified when the Index properties are updated, and the grid moves the content for the updated columns.

            <var>EditorGetValue</var> is a <var>Boolean</var> function used to get the value for a cell editor in the grid. EditorGetValue is used in the implementation of <var>TCustomGrid</var> methods like: <var>EditorShowInCell</var>, <var>ResetEditor</var>, <var>MoveExtend</var>, and <var>DestroyHandle</var>. It is used to get the cell value prior to editing, and to display the value from the cell editor when it is hidden.
          </p>
          <p>
            <var>Validate</var> is a <var>Boolean</var> argument that indicates if the <var>ValidateEntry</var> method is called to validate the edited cell value. When it contains <b>True</b>, <var>ValidateEntry</var> is called prior to calling <var>EditorDoSetValue</var> and/or <var>EditorHide</var>.
          </p>
          <p>
            The return value contains <b>True</b> when the edited cell value is valid. It also contains <b>True</b> if a cell editor has not been assigned or is not visible, or the method was called at design-time or during component destruction.

        <descr>
          <p>
            <var>EditorPos</var> is a procedure used to set the position and size for an active cell editor in the grid. EditorPos posts messages to the <var>Editor</var> for the grid, and requires a valid handle for both the grid control and the editor control. No actions are performed in the method when a Handle has not been allocated for the grid or when Editor is unassigned (contains <b>Nil</b>).
          </p>
          <p>
            A <var>TGridMessage</var> instance with the values in Grid, Col, and Row is dispatched to the Editor to set the Editor position. The bounds for the editor rectangle is calculated and adjusted when needed.
          </p>
          <p>
            The <var>Font</var> for the grid control is assigned to the <var>Canvas</var> where the editor control is drawn.
          </p>
          <p>
            A TGridMessage instance with the values in Grid, Col, Row, and the calculated bounds is dispatched to the Editor to set the Editor bounds.
          </p>
          <p>
            EditorPos is called when visual properties are modified in the control and the editor control is visible. For example: SetRowHeight, SetDefRowHeight, AdjustEditorBounds,  SetEditorBorderStyle, SetEditorValue, EditorWidthChanged, GridMouseWheel, WMHScroll, and WMVScroll.

          <p>
            <var>InternalAutoFillColumns</var> is a procedure used to resize one or more columns to fill the client area for the grid control. No actions are performed in the method if <var>AutoFillColumns</var> contains <b>False</b>, or when the method has already been called but has not yet completed.
          </p>
          <p>
            InternalAutoFillColumns calls <var>GetAutoFillColumnInfo</var> to accumulate the fixed cell width,  data width, and sizing priority for each of the <var>Columns</var> defined in the grid. At least one of the cells in the grid must have sizing priority; the last non-fixed column is expanded to fill the client area in the grid when no other column has sizing priority.
          </p>
          <p>
            InternalAutoFillColumns is called from the UpdateCachedSizes method.

        <descr>
          <p>
            <var>Click</var> is an overridden method used to perform action needed when a mouse click occurs in the control. The grid control provides an internal flag to suppress mouse click handling when the event occurs in a "hot zone" (fixed header cells for columns or rows). Click checks the value in the internal flag, and calls the inherited method when the click occurs in the "normal" data cells for the grid.
          </p>
          <p>
            Click is called from methods like <var>SetCol</var>, <var>SetRow</var>, and <var>SetColRow</var> to emulate a mouse click when values are assigned to the <var>Col</var> and/or <var>Row</var> properties.

        <descr>
          <p>
            <var>DblClick</var> is an overridden method used to perform actions needed when a mouse Double Click event occurs in the grid control.
          </p>
          <p>
            <var>SelectActive</var> is set to False to ignore an active cell or range selection in the control. The internal <var>TGridState</var> member for the control is set to <var>gsNormal</var> to reflect the new state for the control.
          </p>
          <p>
            DblClick uses values in the <var>Options</var> property to determine whether double click is enabled for column or row sizing operations in the control. Some of the Options values relevant to DblClick include:
          </p>
          <dl>
            <dt>goColSizing</dt>
            <dd>Column sizing in enabled for the control.</dd>

            <dd>A mouse double click resizes the column automatically.</dd>
          </dl>
          <p>
            When the needed Options values are present, and match the current <var>CursorState</var> for the control, the corresponding action is performed. <var>AutoAdjustColumn</var> is called for a column resize action. <var>RestoreCursor</var> is called, and <var>HeaderSized</var> is called to signal completion of the column resize operation. Row resize actions for double click mouse events are not currently implemented.
          </p>
          <p>
            If the values in Options or CursorState do not meet the required conditions, the inherited method is called.

        <descr>
          <p>
            <var>DrawCellGrid</var> is a procedure used to draw cell grid lines for both a fixed and a non-fixed cell in the grid control.
          </p>
          <p>
            DrawCellGrid ensures that the control <var>Canvas</var> (and its <var>Pen</var>) are updated to use the values needed to draw the fixed or non-fixed cell at the location specified in <var>ACol</var> and <var>ARow</var>.
          </p>
          <p>
            For a fixed cell (when <var>gdFixed</var> is in AState), grid lines are drawn when <var>gdoFixedVertLine</var> or <var>gdoFixedHorzLine</var> is found in the <var>Options</var> property. The Pen in the control Canvas is updated to reflect a non-zero value in <var>GridLineWidth</var>.
          </p>
          <p>
            When <var>Flat</var> is set to <b>False</b>, the value in AState is used to determine the color used for the Pen. Canvas drawing methods, like <var>MoveTo</var> and <var>LineTo</var>, are used to draw the cell grid lines at the coordinates in ARect. The value in <var>UseRightToLeftAlignment</var> determines how values in ARect are adjusted for the operation.
          </p>
          <p>
            When Flat is set to <b>True</b>, the value in <var>FixedGridLineColor</var> is used as the color for the Pen.
          </p>
          <p>
            For a non-fixed cell (gdFixed is not in AState), grid lines are drawn when <var>gdoVertLine</var> or <var>gdoHorzLine</var> is found in the Options property. The Pen in the control Canvas is updated to use the GridLineWidth, <var>GridLineStyle</var>, and <var>GridLineColor</var> for the control. Canvas drawing methods, like MoveTo and LineTo, are used to draw the cell grid lines at the coordinates in ARect. The value in UseRightToLeftAlignment determines how values in ARect are adjusted for the operation.
          </p>
          <p>
            DrawCellGrid is called from the <var>DrawCell</var> method after preparing the Canvas and drawing the filled rectangle with the background for the cell.

            <var>DrawGridCheckboxBitmaps</var> is used to draw a bitmap used for a checkbox at the cell coordinates in <var>ACol</var> and <var>aRow</var>. <var>AState</var> contains the checkbox state for the cell, and determines the image displayed in the specified cell.
          </p>
          <p>
            GetImageForCheckBox is called to get the image list, image index, and/or bitmap used in the cell. Use the OnUserCheckBoxImage or OnUserCheckboxBitmap event handler to get a custom image or bitmap displayed for the value in AState. If GetImageForCheckBox is unable to find either a bitmap or an image, ThemeServices is used to get the theme element details for the checkbox state.
          </p>
          <p>
            The bitmap/image/theme element may be scaled if the control Font uses a display density (PPI) different than the value used for the Screen.
          </p>
          <p>
            When Columns has been Enabled,  the GetColumnAlignment and GetColumnLayout methods are used to determine the image alignment and layout used for the checkbox cell. If Columns has not been enabled, the image is centered horizontally in the cell using the vertical alignment defined for text on the Canvas.
          </p>
          <p>
            DrawGridCheckboxBitmaps adjusts ARect to use the cell padding for the control (varCellPadding) along with the size, alignment and layout needed for the grid column.
          </p>
          <p>
            The checkbox bitmap is drawn using the mechanism needed for the image source; ThemeService.DrawElement, Canvas.StretchDraw, or TScaledImageListResolution.StretchDraw.

            <var>DrawColumnTitleImage</var> is a method used to draw the image(s) used in the column title at the index position in <var>AColumnIndex</var>. <var>ARect</var> contains the bounds for the cell where the image is drawn.
          </p>
          <p>
            When AColumnIndex contains the same value as the <var>SortColumn</var> property, a sort indicator is drawn for the column. <var>GetSortTitleImageInfo</var> is called to determine whether theme services is used to drawn native sort buttons using theme element details. The image size may be scaled when the display density (PPI) for the control <var>Font</var> has a value other than 96.
          </p>
          <p>
            DrawColumnTitleImage ensures that image padding (DEFIMAGEPADDING) is applied to the bounds in ARect. The top and bottom bounds are adjusted so that the image is vertically centered in the area in ARect.

          <p>
            DrawColumnTitleImage calls the <var>DrawElement</var> method in <var>ThemeServices</var> to draw the sort indicator.

          <p>
            When native sort indicators are not used for the column, an image scaled to the display density is retrieved from the image list. DrawColumnTitleImage ensures that image padding (DEFIMAGEPADDING) is applied to the bounds in ARect. The top and bottom bounds are adjusted so that the image is vertically centered in the area in ARect. The <var>Draw</var> method in the scaled image resolution is called to draw the image on the control Canvas.

            <var>TitleImageList</var> is used to determine if an additional image is displayed for the column at AColumnIndex. When TitleImageList has been assigned, the <var>GetTitleImageInfo</var> method is called to get the image list and position used for the column. When an image is defined in <var>Columns</var>, an image scaled to the size size needed for the display densitity (PPI) is retrieved from TitleImageList. The bounds in ARect is adjusted to include  padding around the image (DEFIMAGEPADDING) usiing the image layout for the column.

          <p>
            DrawRow iterates over the columns in the visible area in the grid to determine if each cell fits vertically within the clipping rectangle for the control Canvas. If column spanning (goColSpanning) has been enabled in the Options for the grid, the cell extent is determined for each cell. DoDrawCell is called to render the cells.

          <p>
            <var>FontChanged</var> is an overridden method used to perform actions needed when the <var>Font</var> for the control has been changed.
          </p>
          <p>
            FontChanged ensures that the internal default heights for rows and columns are reset to <b>0</b> (<b>zero</b>). This forces the default column and row heights to be recalculated when the <var>DoAutoAdjustLayout</var> method is called.
          </p>
          <p>
            When <var>csCustomPaint</var> is included in <var>ControlState</var>, the Font is assigned to the <var>Canvas</var> for the control.
          </p>
          <p>
            Otherwise, the FontChanged method is called for the ancestor class and the <var>Columns</var> collection (when Enabled). If the default title font is used for the control, the Font is assigned to <var>TitleFont</var> property.
          </p>
          <p>
            FontChanged is assigned as the <var>OnChange</var> event handler for the <var>Font</var> property in the constructor for the class instance.

When editing is permitted, the <var>Columns</var> collection is used to get the ButtonStyle stored in the <var>TGridColumn</var> instance. If the column uses the cbsAuto button style and has a valid non-empty PickList, the cbsPickList button style is used.
          </p>
          <p>
            If Columns has not been enabled, the cbsAuto button style is always used for the Editor control.

          <p>
            GetDefaultEditor calls <var>EditorByStyle</var> to create the Editor with the button style needed for the control. The return value is <b>Nil</b> if the column does not allow editing, or the current cell is a fixed column or row header.
          </p>
          <p>
            For an Editor using the cbsPickList button style, its items and drop-down row count are set using values from the column definition in Columns.

          <p>
            GetDefaultEditor is called from the <var>SelectEditor</var> method prior to selecting the cell and signalling the <var>OnSelectEditor</var> event handler (when assigned). Use the OnSelectEditor event handler to override the Editor style or its configuration.

            <var>MouseUp</var> is an overridden method in <var>TCustomGrid</var> used to perform actions needed when a mouse up event has been received for the grid control. It calls the inherited method on entry to signal the OnMouseUp event handler (when assigned). MouseUp performs additional actions based on the grid zone where the mouse up event occurred and the current grid state flags for the control.
          </p>
          <p>
            For example:
          </p>
          <dl>
            <dt>
              Mouse event on a fixed header for the grid.

              Calls HeaderClick for the column header under the mouse pointer. Changes the sort order in the column when enabled. Occurs when gsHeaderClicking is in the grid state flags.
            </dd>
            <dt>
              Mouse event on a column button in the grid header.
            </dt>
            <dd>
              Calls DoEditButton to signal the OnEditButtonClick or OnButtonClick event handlers (when assigned). Occurs when gsButtonColumnClicking is in the grid state flags.
            </dd>
            <dt>
              Mouse event on a non-fixed cell in the grid control.
            </dt>
            <dd>
              Selects and displays an editor for the cell, and calls the CellClick method to apply the mouse event to the cell. If a selection is already active in the control, it is extended to include the range of cells ending at the mouse pointer. Occurs when gsNormal or gsSelecting is in the grid state flags.
            </dd>
            <dt>
              The mouse event occurs when dragging a column header.
            </dt>
            <dd>
              Moves the dragged column to the column position under the mouse pointer. Calls HeaderClick to refresh the sort order for cells in the column. Occurs when gsColMoving is in the grid state flags.
            </dd>
            <dt>
              The mouse event occurs when dragging a row header.
            </dt>
            <dd>
              Moves the dragged row to the row position under the mouse pointer. Calls HeaderClick to refresh the sort order for cells in the row. Occurs when gsRowMoving is in the grid state flags.

            <dt>
              The mouse event occurs when resizing a column header.
            </dt>
            <dd>
              Calls ResizeColumn to apply the new column size, and calls the HeaderSized method for the resized column number. Occurs when gsColSizing is in the grid state flags.
            </dd>
            <dt>
              The mouse event occurs when resizing a row header.
            </dt>
            <dd>
              Calls ResizeRow to apply the new row size, and calls the HeaderSized method for the resized row  number. Occurs when gsRowSizing is in the grid state flags.
            </dd>
          </dl>

            <var>AutoEdit</var> is a <var>Boolean</var> property which indicates if edit mode is automatically entered when a cell is selected in the grid control. The default value for the property is True.
          </p>
          <p>
            When AutoEdit is set to True, the cell Editor is automatically displayed when a non-fixed cell is entered using keyboard navigtation or a mouse click. When AutoEdit is set to False, the cell Editor is not displayed until toggled.  Use the F2 or Enter key to activate a cell Editor. Use a second mouse click in the active cell to display the cell Editor.
          </p>
          <p>
            AutoEdit does not allow a cell to be edited if the column definition in the Columns collection is defined as ReadOnly.

          </p>
          <p>
            There are several editor styles available for columns in the grid control: String, Button, Composite, and Pick List. Button editors display a button that can be clicked to perform actions which determine the value for the cell. A composite editor uses an editor for the string value and a button for additional actions. A pick list editor allows selection of oneof the predetermined values for the cell. The String editor is essentially a TEdit control, and is the default editor style used in the grid control.
          </p>
          <p>
            The Editor style is determined either by examing values in the column definition stored in the Columns property, or using the OnSelectEditor event handler. OnSelectEditor is signalled  when Columns has not been Enabled in the grid.
          </p>
          <p>
            Editor display behavior is controlled by properties like Options and AutoEdit.
          </p>
          <p>
            Options can be used to enabled / disabled cell editor features using the following:

          <dl>
            <dt>goEditing</dt>
            <dd>Cell editing is allowed for the grid control. Omit to disable cell editing.</dd>

            The AutoEdit property determines whether a cell is automatically placed in edit mode as soon as  it is selected. This is basically the same as including goAlwaysShowEditor in the Options property.

          <p>
            <var>OnDrawCell</var> is a <var>TOnDrawCell</var> property with the event handler signalled to render a cell in the grid control. Parameters passed to the event handler identify the column and row numbers for the cell, and the drawing state.
          </p>
          <p>
            OnDrawCell can be used along with the default drawing mechanism for the grid control. Set the <var>DefaultDrawing</var> property to <b>True</b> to allow the grid to render the cell background, state, and focus. Use OnDrawCell to handle the text which appears in the specified cell.
          </p>
          <p>
            OnDrawCell can be used to render all aspects of a cell by setting DefaultDrawing to <b>False</b>. In this situation, the event handler must handle rendering the background, state, focus, and text for the cell.
          </p>
          <p>
            OnDrawCell is signalled (when assigned) from the <var>DrawCell</var> method at run-time. It is not signalled at design-time. OnDrawCell occurs after the canvas has been configured using <var>PrepareCanvas</var>, and after <var>DefaultDrawCell</var> when DefaultDrawing is <b>True</b>.

        <descr>
          <p>
            <var>FixDesignFontsPPI</var> is an overridden  procedure used to adjust the assigned font size for grid columns and their titles to the specified design-time Pixels Per Inch (PPI). This is needed because the display density (PPI) used for fonts is not stored in Form resource (.LFM) files. When the design-time PPI is different than the run-time setting, font scaling issues can occur.
          </p>
          <p>
            FixDesignFontsPPI restores the design-time font PPI so it can be used in the LCL Scaling mechanism. FixDesignFontsPPI calls the inherited method on entry, and sets the value for the <var>PixelsPerInch</var> property in <var>TitleFont</var> when needed. Column definitions stored in the <var>Columns</var> property are also adjusted (when needed) by calling the FixDesignFontsPPI method for each of the <var>TGridColumn</var> instances in the container.
          </p>
          <p>
            FixDesignFontsPPI is called when scaling is enabled, and the Form which hosts the control calls its <var>Loaded</var> method during LCL streaming.

          <p>
            <var>ScaleFontsPPI</var> is an overridden procedure used to resize fonts in the control to the specified display density (Pixels per Inch) using the scaling factor in <var>AProportion</var>. This occurs when the run-time PPI setting for a font differs from the design-time value stored in the component resource.
          </p>
          <p>
            ScaleFontsPPI is overridden to apply the scaling factor to the <var>Font</var> and <var>TitleFont</var> for the control, and any fonts assignments in the <var>Columns</var> collection. The inherited <var>DoScaleFontsPPI</var> method is called to apply the scaling factor to the TFont instance passed as an argument.

            The OnDrawCell event handler is provided to render the cell content in the grid, and can be used to render images or directly access the Canvas for the control. Default cell drawing logic is also implemented using the properties and methods from the ancestor class, and may be accessed from within the OnDrawCell event handler.

          Uses the Color from the Parent control, when enabled.
        </short>
        <descr>
          <p>
            ParentColor determines if the control should use the Color from the Parent control, when enabled. The default value for the property is False in TDrawGrid.
          </p>
          <p>
            When this property is True, all changes to the Color of the parent will also be applied to the Color of the control, ensuring that they both contain same value. If the Color of the control is changed by the application, then ParentColor will be automatically set to False.
          </p>
         <p>
           Using ParentColor when the Color value is clDefault can cause problems in resolving the actual color value. To obtain the Color property of a control while taking into account clDefault and ParentColor, use the GetColorResolvingParent method. This method might return a non-RGB color, but will never return clDefault. To obtain a purely RGB result use the GetRGBColorResolvingParent method.

            Adjusts the column specified in <var>ACol</var> to use the width needed for the font and image(s) for the column. No actions are performed in the method when ACol is not a valid column index.
          </p>
          <p>
            <var>AutoAdjustColumn</var> calculates the width need for the image (if any) used in the column header, and adds the padding specified in the DEFIMAGEPADDING constant. If a sort indicator is used, the same actions are performed for the sort image. The image widths may be scaled to the current display density if the PPI for the control Font differs from the value in TitleImageList.
          </p>
          <p>
            AutoAdjustColumn visits the rows in the grid to calculate the maximum width required for the text in each. A temporary Canvas instance is used to calculate the width for the text. When Columns has been enabled, fonts assigned to the TGridColumn instance are used. When Columns has not been enabled, TitleFont is used for fixed rows or columns. Otherwise, the Font for the grid is used.
          </p>
          <p>
            For multi-line columns, the DrawText routine is called to calculate the text rectangle. For single-line columns, the TextExtent method in the canvas is used. Cell padding is added to the calculated column width using the value in varCellPadding. The derived column width is stored  in the ColWidths property for the column specified in ACol.
          </p>
          <p>
            AutoAdjustColumn is called from the DblClick method when column auto-sizing <b>and</b> double click auto-sizing have been enabled in the Options for the grid. It is also called from the AutoAdjustColumns, AutoSizeColumns, and AutoSizeColumn methods.

          <p>
            InsertRowWithValues examines Values to determine whether the grid has a column for each of the string values. When Values has more entries than columns available in ColCount, new columns are added to the grid. When Columns has been Enabled, the Add method in Columns is called to create any missing column definitions. The title for a column added to the collection is set to an empty string (''). When Columns has not been enabled, the value in ColCount is set to the length of the Values array.
          </p>
          <p>
            InsertRowWithValues calls InsertColRow to increment the row count for the grid, and assigns each String in Values to the corresponding Cells in the grid control.

            TStringGrid is designed for use with string content stored in its cells.

        </short>
        <descr>
          <p>
            ParentColor determines if the control should use the Color from the Parent control, when enabled. The default value for the property is False in TStringGrid.
          </p>
          <p>
            When this property is True, all changes to the Color of the parent will also be applied to the Color of the control, ensuring that they both contain same value. If the Color of the control is changed by the application, then ParentColor will be automatically set to False.
          </p>
         <p>
           Using ParentColor when the Color value is clDefault can cause problems in resolving the actual color value. To obtain the Color property of a control while taking into account clDefault and ParentColor, use the GetColorResolvingParent method. This method might return a non-RGB color, but will never return clDefault. To obtain a purely RGB result use the GetRGBColorResolvingParent method.

            <b>Customizing Grids</b>
          </p>
          <p>
            Grids are components derived from the <var>TCustomControl</var> class and do not  have a native widget associated with them. So they are not restricted by the look of the current interface theme. This can be both an advantage and a disadvantage: usually programmers want to create a uniform-look application. Lazarus grids are flexible enough to allow programmers to make them look similar to other native controls; alternatively they can customize the grid to obtain almost the same look in any platform or widget interface (with the exception of scrollbars, whose look is still determined by the current theme).
          </p>
          <p>
            Some properties can affect the way the grid looks by acting when the cell is about to be painted in <var>PrepareCanvas/OnPrepareCanvas</var> by changing default canvas properties like brush color or font. Following is a list of such properties:

            <b>Description of the Grid Drawing Process</b>
          </p>
          <p>
            Like other custom controls, the grid is drawn using the paint method. In general terms the grid is drawn by painting all rows, and each row by painting its individual cells. The process is as follows:
          </p>
          <ul>
            <li>First, the visible cells area is determined: each row is tested to see if it intersects the canvas clipping region; if it's OK, then the visible area is painted by drawing columns of each row.
            </li>
            <li>
              The column and row values are used to identify the cell that is about to be painted and again each column is tested for intersection with the clipping region; if everything is OK, some additional properties like the cell's rectangular extent and visual state are passed as arguments to the DrawCell method.
            </li>
            <li>
              <p>
                As the drawing process is running, the visual state of each cell is adjusted according to grid options and position within grid. The visual state is retained in a variable of type <var>TGridDrawState</var> which is a set with following elements:
              </p>

              <p>
                <var>DrawCell</var> - The DrawCell method is virtual and may be overridden in descendent grids to do custom drawing. The information passed to <var>DrawCell</var> helps to identify which particular cell is being painted, the physical area occupied on the screen and its visible status. See <link id="TCustomGrid.DrawCell">DrawCell</link> reference for details. For each cell the following occurs:
              </p>
              <ul>
                <li>
                  <b>PrepareCanvas</b>  - If the DefaultDrawing is set, the grid canvas is setup with default properties for brush and font based on current visual state. For several design and run-time properties, the text alignment is set to match programmer selection in custom columns if they exists.  If DefaultDrawing is false, brush color is set to clWindow and Font color to clWindowText, the text alignment is set with grids defaultTextStyle value.
                </li>
                <li>
                  <b>OnPrepareCanvas</b> -  If the programmer wrote an event handler for the
                  <var>OnPrepareCanvas</var> event, it is called at this point. This event can be used for doing simple customization like changing a cell's background color, font's properties like color, font face and style, Text layout like different combinations of left, center, top, bottom, right alignment, etc. Any change made to the canvas for a particular cell in this event would be lost, because the next cell drawing will reset canvas again to a default state. So it's safe doing changes only for a particular cell or cells and forget about it for the rest. Using this event sometimes helps to avoid using the <var>OnDrawCell</var> grid event, where users would be forced to duplicate the grid's drawing code.
                </li>
                <li>
                  <b>OnDrawCell</b> - Next, if no handler for the <var>OnDrawCell</var> event was specified, the grid calls the <var>DefaultDrawCell</var> method which simply paints the cell background using the current canvas brush color and style. If the <var>OnDrawCell</var> handler exists, the grid first paints the cell background, but only if the <var>DefaultDrawing</var> was set; then it calls the <var>OnDrawCell</var> event to do custom cell painting. Usually programmers want to do custom drawing only for particular cells, but standard drawing for others: in this case, they can restrict custom operation to certain cell or cells by looking into <var>ACol, ARow</var> and <var>AState</var> arguments, and for other cells simply call the <var>DefaultDrawCell</var> method and let the grid to take care of it.
                </li>
                <li>
                  <b>Text</b> - At this point, if the <var>DefaultDrawing</var> is true, the cell's text content is painted (only for <var>TStringGrid</var>).
                </li>
                <li>
                  <b>Grid lines</b> - The last step for each cell is to paint the grid lines: if grid options <var>goVertLine, goHorzLine, goFixedVertLine</var> and
                  <var>goFixedHorzLine</var> are specified the cell grid is drawn at this point. Grids with only rows or only cols can be obtained by changing these options. If the programmer elected to have a "themed" look it is done at this point also (see TitleStyle).
                </li>
                <li>
                  <b>FocusRect</b> - When all columns of the current row have been painted it is time to draw the focus rectangle for the current selected cell or for the whole row if the <var>goRowSelect</var> option is set.
                </li>
              </ul>
            </li>
          </ul>
          <p>
            <b>Grid Cell Selection</b>
          </p>
          <p>
            The location of a grid's current (focused) cell (or row) can be changed using keyboard, mouse or through code. In order to change cell focus successfully to another position, we must test  the target position to see if it is allowed to receive cell focus. When using the keyboard, <var>AutoAdvance</var> performs part of the process by finding what should be the next focused cell. When using mouse clicks or moving by code, focus will not move from the current cell unless the target cell is permitted to receive focus.
          </p>
          <p>
            The grid calls <var>SelectCell</var> to see if a cell is focusable: if this function returns true, then the target cell identified with arguments <var>aCol</var> and <var>aRow</var> is focusable (the current implementation of <var>TCustomGrid</var> simply returns true). <var>TCustomDrawGrid</var> and hence <var>TDrawGrid</var> and <var>TStringGrid</var> override this method and check first if  a cell is any wider than 0; normally you don't want a 0 width cell selected so a cell with this characteristics is skipped automatically in the process of finding a suitable cell. The overridden method <var>SelectCell</var> also calls the user configurable event <var>OnSelectCell</var>: this event receives the cell coordinates as arguments and always returns a default result of True.
          </p>
          <p>
            Once a cell is known to be focusable and we are sure a movement will take place, the method <var>BeforeMoveSelection</var> is called; this in turns triggers the <var>OnBeforeSelection</var> event. This method's arguments are the coordinates for the new focused cell; at this point any visible editor is hidden too. The "before" word means that selection is not yet changed and current focused coordinates can be accessed with <var>grid.Col</var> and <var>grid.Row</var> properties.
          </p>
          <p>
            After that, the internal focused cell coordinates are changed and <var>MoveSelection</var> is called; this method's purpose (if set) is to trigger the <var>OnSelection</var> event (this is a notification that the focused cell has changed and the new cell coordinates are available through grid.row and grid.col properties).
          </p>
          <p>
            Note that is not good to use the <var>OnSelectCell</var> event to detect cell focus changes, as this event will be triggered several times even for the same cell in the process of finding a suitable cell. Is better to use <var>OnBeforeSelection</var> or <var>OnSelection</var> events for this purpose.
          </p>

            <b>Using Cell Editors</b>
          </p>
          <p>
            Users can specify what editor will be used for a cell using one of two methods.
          </p>
          <ol>
            <li>
              <b>Using a custom column and selecting the ButtonStyle of the column.</b> In this method the user can select the style of the editor that will be shown. Available values are: <var>cbsAuto, cbsEllipsis, cbsNone, cbsPickList, cbsCheckboxColumn</var>.
            </li>
            <li>
              <p>
                <b>Using the OnSelectEditor Grid Event</b>
              </p>
              <p>
                Here the user specifies in the <var>Editor</var> parameter which editor to use for a cell identified by <var>aCol</var>, <var>ARow</var> in a <var>TCustomDrawGrid</var> derived grid or <var>TColumn</var> in <var>TCustomDBGrid</var>. The public <var>EditorByStyle()</var> function takes as parameter one of the following values: <var>cbsAuto, cbsEllipsis, cbsNone, cbsPickList, cbsCheckboxColumn</var>.
              </p>
              <p>
                This method takes precedence over the first one using custom columns. A Custom cell editor can be specified here, with values specific to the cell, row or column.
              </p>
            </li>
          </ol>
          <p>
            <b>Description of Editor Styles</b>
          </p>
          <p>
            The following is a description of the editor styles. They are enumerated values of type <var>TColumnButtonStyle</var> and so they are prefixed by 'cbs'. This type was used to remain compatible with Delphi's <var>DBGrid</var>.
          </p>
          <ul>
            <li>
              <b>cbsAuto</b> - This is the default editor style for TCustomGrid derived grids. The TStringCellEditor derived from TCustomMaskEdit is specialized to edit single line strings and is used by default in TStringGrid and TDrawGrid. When using Custom Columns, if the programmer filled the Column's PickList property, this behaves as if cbsPickList editor style was set. For a TCustomDBGrid that has a field of type Boolean, it behaves as if cbsCheckBoxColumn editor style was specified. This is the recommended value for custom cell editors.
            </li>
            <li>
              <p>
                <b>cbsEllipsis</b> - This editor style is the most generic one. A button with ellipsis (...) appears in the editing cell and the programmer can use the OnEditButtonClick grid event to take any programmed action  when the user presses the button. For example a calendar dialog could pop up to allow the user to select a specific date,  a file open dialog could appear to find files, or a calculator could appear so the user could enter the numeric result of calculations, etc.
              </p>
              <ul>
                <li>
                  OnEditButtonClick is just a notification, to find out in which cell a button has been clicked by taking  a look at the grid.Row and grid.Col properties.
                </li>
                <li>
                  A DBGrid has specific properties to retrieve the active column or field and because this event occurs in the active record, it could update the information in the active field.
                </li>
                <li>
                  This editor style is implemented using TButtonCellEditor, a direct descendant of TButton.
                </li>
              </ul>
            </li>
            <li>
              <b>cbsNone</b> - This editor style instructs the grid not to use any editor for a specific column; it behaves as if the cell were read-only.
            </li>
            <li>
              <p>
                <b>cbsPickList</b> - Used to present the user with a list of values that can be entered. This editor style is implemented using TPickListCellEditor, a component derived from TCustomComboBox. The list of values that are shown is filled in one of two ways depending on the method used to select the editor style.
               </p>
               <p>
                 When using custom columns, programmers can enter a list of values using the PickList property for the column.
               </p>
            </li>
            <li>
              <p>
                <b>cbsCheckboxColumn</b> - This editor style is at the moment only available in TDBGrid. If a field's contents associated with the column are restricted to a pair of values, for example, yes-no, true-false, on-off, 1-0, etc then cbsCheckboxColumn is used to modify the appearance of a column by using a checkbox representation that the user can toggle by using a mouse click or pressing the SPACE key.
              </p>
              <ul>
                <li>
                  If a ButtonStyle for a column is set to cbsAuto and DBGrid detects that the field associated with the column is a Boolean field, then the grid uses this editor style automatically. This automatic selection can be disabled or enabled using DBGrid's OptionsExtra property; setting dgeCheckboxColumn element to false disables this feature.
                </li>
                <li>
                  The values that are used to recognize the checked or unchecked states are set in a column's properties ValueChecked and ValueUnchecked.
                </li>
                <li>
                  At any moment, the field value can be in one of three states: Unchecked, Checked or Grayed.
                </li>
              </ul>
            </li>
          </ul>
