            <var>ActivePageComponent</var> is a <var>TCustomPage</var> property which indicates the active page component for the tabbed control.
          </p>
          <p>
            <var>PageIndex</var> is used to access the page instance in <var>Page</var> with the property value. The property value is <b>Nil</b> when PageIndex contains a value that is not in the range <b>0..<var>PageCount</var>-1</b>.
          </p>
          <p>
            Setting a new value for the property causes the <var>IndexOf</var> method to be called to locate the value in the list of pages. PageIndex is updated to reflect the position for the specified page, and may contain <b>-1</b> if pages are not used in the tabbed control.

          <p>
            Changing the value in the property cause the Parent control to be updated to reflect the new value. No actions are performed in the method at design-time, or when the property value is not different than the stored value.

          <p>
            When the Parent control has been assigned and has a handle allocated, the TCustomTabControl in Parent is updated to reflect the new value for the property. When True, the active page in the Parent control is changed to the current page instance if one has not already been assigned in the Parent. The page and its handle are removed from the Tab control when the property value is False.
          </p>
          <p>
            Use IsControlVisible to determine if the page is currently the active page displayed in the Parent tab control.

            <var>Paint</var> is a method used to render the tab control to its canvas. It handles the background and tabs for the control excluding any button decorations. Buttons are handled in a differ component. Paint adjusts the display rectangle in ARect to reserved a single pixel on the edge indicated in the <var>TabPosition</var> property. This avoids drawing a border on the edge where the control is aligned.

            Paint uses <var>ThemeServices</var> to get theme elements available for a tab control, and to draw the control to its <var>Canvas</var> using the theme details. A raised 3D frame is drawn around the control. At design-time, the <var>Caption</var> for the control is drawn centered in its display area.

            Selected is a Boolean property which indicates if the list item has been selected. The property value is determined by examining the internal TListItemStates set for the class instance.

          <dl>
            <dt>Icon View</dt>

            <dt>List View</dt>
            <dd>
              Each list item has a small icon with a caption, and is displayed in a single column in the control.
            </dd>
            <dt>Report View</dt>
            <dd>
              Each list item is displayed on a single line, with sub-items displayed as additional columns. The first column has a small icon and a caption. Other columns contain the text for the sub-items.
            </dd>
          </dl>

            <var>ResizeLastColumn</var> is a method used to make the last visible column fill the remaining unused width for the control.
          </p>
          <p>
            ResizeLastColumn is relevant when <var>ViewStyle</var> is set to <var>vsList</var> or <var>vsReport</var>, and <var>ColumnCount</var> is not set to 0 (zero). No actions are performed in the method if both conditions are not met.
          </p>
          <p>
            ResizeLastColumn examines the values in <var>Columns</var> (in reverse order) to find the last <var>TListColumn</var> instance with its <var>Visible</var> property set to <b>True</b>. The accumulated width for the preceding visible columns (and borders) is calculated. The difference between ClientWidth and the accumulated width is used for the last column when it is a positive non-zero value.
          </p>
          <p>
            The column affected in the method has its <var>AutoSize</var>, <var>MinWidth</var>, and <var>MaxWidth</var> properties reset before applying the new <var>Width</var>.
          </p>
          <p>
            ResizeLastColumn is used when <var>AutoWidthLastColumn</var> is set to <b>True</b>. The method is called when the bounds for the control have been changed, or when the value in AutoWidthLastColumn has been changed.

          <p>
            <var>ColClick</var> is a method used to handle a mouse click on a column header when the list view control is in Report view (ViewStyle = vsReport).
          </p>
          <p>
            ColClick ensures that the Editor for the control is hidden when it has been assigned and displayed for the control.
          </p>
          <p>
            AColumn is the TListColumn instance representing the column header clicked on the control. The OnColumnClick event handler is signalled (when assigned) if  ColumnClick is set to True. The event handler can be used to adjust property  values in the column argument or the list view control as needed.
          </p>
          <p>
            ColClick uses the value in AutoSort to determine if the control is updated to reflect a change to the sort column or its order indicator. No additional actions are performed when AutoSort is False or SortType is stNone.
          </p>
          <p>
            When AutoSort is set to True, the Index in AColumn is used to set the value for the SortColumn property, When AutoSortIndicator is enabled, the Columns for the control are updated to clear any previous sort indicators when a new sort column has been clicked.

        <descr>
          <p>
            <var>Delete</var> is a method used to delete the list item specified in AItem.
          </p>
          <p>
            In Delphi, Delete is called when Items.Delete is executed.  The OnDeletion event handler is signalled each time the method is called, even when list items are freed from the Items container.
          </p>
          <p>
            The Lazarus implementation differs. It uses a flag value in AItem to determine if the method has been called when the list item is freed, or when the Delete method in the list item has been called explicitly.
          </p>
          <p>
            Delete is called from the DoDeletion method if an overridden Delete method has  been implemented. The OnDeletion event handler is signalled when Delete has been explicitly called, and when the Delete method has not been overridden.
          </p>
          <p>
            While not 100% Delphi compatible, it is more compatible than previous LCL versions.

          <p>
            OnDeletion is a TLVDeletedEvent property with the event handler signalled when a list item is deleted from the Items container. It provides better compatibility with the Delete method as implemented in Delphi.
          </p>
          <p>
            In Delphi, the Delete method is called when the Items.Delete method is called. But calling the method directly will also delete the item and then call the OnDeletion handler.
          </p>
          <p>
            In that case we simply call Items.Delete and this will then call Delete again and in the second run we call the OnDeletion handler. Not 100% Delphi compatible, but more compatible then it was before. (BB)

            Selected is a TListItem property which contains the selected list item in the list view control. Assign a value from the Items property to select the list item.
          </p>
          <p>
            When MultiSelect is enabled, Selected represents the first entry in Items that has its Selected property set to True. If none of the list items has its Selected property set to True, or SelCount is 0, the property value is Nil.
          </p>
          <p>
            When OwnerData (or Virtual Mode) is enabled, Selected refers to the most recent owner data item retrieved when the value in ItemIndex was changed. If the item index was set to -1, the property value is Nil.
          </p>
          <p>
            Assigning a new value to Selected causes the existing list item in the property to be updated. In single select mode (MultiSelect = False), the Selected property for the list item is set to False prior to clearing or reassigning the property value.
          </p>
          <p>
            When MultiSelect is enabled, setting a new value for the property causes the list item to be included in the list of multi-selected Items. If the new value is Nil, all of the entries in Items reset their Selected properties to False. In short, setting Selected to Nil clears any existing multi-selections in Items.
          </p>
          <p>
            Setting a new value for the property causes the OnChange and OnSelectItem event handlers to be signalled (when assigned) when the LVN_ITEMCHANGED notification message is handled for the control.

            <var>TListView </var>- a window showing a list of items which may or may not have associated icons.
          </p>
          <p>
            At first this control looks very like <link id="#lcl.stdctrls.TListBox">TListBox</link> but it has a much higher degree of complexity. It is capable of displaying Items in <var>Columns</var> of <var>Rows</var> and it can have images associated with the list <var>Items</var>.
          </p>
          <p>
            The important information is held in <var>Items</var>, a string-list that can be created using the string-list editor obtained by right-clicking on the ListView in the Form Editor or by clicking on the ellipsis (<b>...</b>) next to the <var>Items</var> entry in the Object Inspector.
          </p>
          <p>
            A typical application might have two ImageLists: one of <var>LargeImages</var> and one of <var>SmallImages</var>, containing two versions of the same collection of images, in large and small format; the index numbers of the first list would correspond with those in the second list.
          </p>
          <p>
            <var>SmallImages</var> (if assigned to a string-list) can be displayed beside the text strings in the list view and the programmer would supply code to ensure that when an item with its associated Small Image was selected, the corresponding Large Image would be displayed in another window.
          </p>
          <p>
            One or more <var>TImageList</var> controls need to be added to the Form Designer and the ImageList Editor can be opened from the pop-up menu obtained by right-clicking on <var>TImageList</var> icon in the Form Designer. The image list can be populated by reading from files. Then in the StringList editor for <var>Items</var> the correct <var>ImageIndex</var> must be assigned to each entry in the list.

        <short>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 TListView.
          </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.

            A progress bar is used to indicate the progress for a lengthy operation. It contains an indicator bar that is updated with the completion percentage for the task. A progress bar can use either horizontal or vertical orientations. The visual appearance of the control can be configured using drawing styles, themes, and other property settings.

          </p>
          <p>
            The control definition itself does not specify the variable upon which the buttons operate. The application programmer is responsible for supplying an event handler for <var>OnClick</var> to determine which button has been selected (designated <var>btNext</var> or <var>btPrev</var>) and incrementing or decrementing the variable in the control with which the UpDown is associated.
          </p>
          <p>
            The amount by which the variable is changed is set by the integer property <var>Increment</var> with the optional multiplier <var>Thousands</var> (a boolean property).
          </p>
          <p>
            For example the UpDown control may be used to move a slider up and down a scale by a specified amount for each click; alternatively a number may be displayed in a text box and clicking the buttons of the UpDown control may increment or decrement the number displayed by a specified amount.

        <short>Indicates if the control depends on access to its WidgetSet class.</short>
        <descr>
          <p>
            FUseWS is a private Boolean member used to indicate if the control depends on  access to its WidgetSet class instance. The value in FUseWS is set in the constructor for the class instance.
          </p>
          <p>
            FUseWS is used in the constructor to ensure that buttons are created for Prev and Next values when they are not part of the widgetset class implementation.
          </p>
          <p>
            FUseWS is used in the InitializeWnd method to determine if the property values must be set in the widgetset class, including: MinPosition, MaxPosition, Position, Increment, Wrap, Orientation, and UseArrowKeys.
          </p>
          <p>
            FUseWS is used in the UpdateOrientation method to determine whether the action is implemented in the widgetset class, or handled in TCustomUpDown.
          </p>
          <p>
            FUseWS is used in the AdjustPos method to determine whether a change in the control value using its buttons is handled in the current class instance, or forwarded to the appropriate button click method in the widgetset class. Similarly, handling for mouse wheel events are determined using the FUseWS member.

      <element name="TUpDown">
        <short>
          <var>TUpDown</var> - a pair of arrow-like buttons which are used to increment or decrement some controlled variable; often attached to a scroll-bar but can also control a digital numeric display.
        </short>

            <var>TUpDown</var> - a pair of arrow-like buttons which are used to increment or decrement some controlled variable; often attached to a scroll-bar but can also control a digital numeric display
          </p>
          <p>
            The control definition itself does not specify the variable upon which the buttons operate. The application programmer is responsible for supplying an event handler for <var>OnClick</var> to determine which button has been selected (designated <var>btNext</var> or <var>btPrev</var>) and incrementing or decrementing the variable in the control with which the UpDown is associated.
          </p>
          <p>
            The amount by which the variable is changed is set by the integer property <var>Increment</var> with the optional multiplier <var>Thousands</var> (a boolean property).
          </p>
          <p>
            For example the UpDown control may be used to move a slider up and down a scale by a specified amount for each click; alternatively a number may be displayed in a text box and clicking the buttons of the UpDown control may increment or decrement the number displayed by a specified amount.

          <p>
            Use <var>TToolButton</var> to implement buttons on a toolbar. While other controls (including <var>TButton</var> and <var>TSpeedButton</var>) can be placed on toolbars, <var>TToolButton</var> utilizes special toolbar features to simplify the configuration of buttons and offers added display options such as edge borders and transparency.
          </p>
          <p>
            To place tool buttons on a toolbar at design time, select the toolbar, right-click, and choose New Button.

            Paint calculates the area display area for the button, and calls GetButtonDrawDetail to get the Theme Element Details for the control.
          </p>
          <p>
            When an OnPaintButton event handler has been assigned for the ToolBar, it is used to render the button using the theme details. No additional actions are performed in the method.
          </p>
          <p>
            When OnPaintButton is unassigned, the default drawing routines are used to render the button on the Canvas for the control. This includes decorations like a drop-down indicator, an image using the required state, the Caption text, button relief, and dividers or separators. Methods in ThemeServices are called to render the control to the Handle for the Canvas.
          </p>
          <p>
            Paint calls the inherited method prior to exit to signal the OnPaint event handler (when assigned).

          <p>
            GetCurrentIcon is a method used to get information for the icon drawn on the tool button. It returns values in the variable parameters with the scaled image list for the icon, its position in the image list, and the drawing effect for the image.
          </p>
          <p>
            ImageList is the scaled image list with the images from the parent tool bar. It is re-created in the method and uses the image size from the parent tool bar scaled to the run-time display density (PPI). The images in the list are retrieved from the Images, HotImages, or DisabledImages properties in the parent tool bar and reflect the values in the Enabled property and the tool button flags. The default value is Nil (unassigned).
          </p>
          <p>
            TheIndex is the position in the image list for the icon image. It defaults to the value in the ImageIndex property.
          </p>
          <p>
            TheEffect is a TGraphicsDrawEffect value that indicates the drawing effect to apply to the tool button. It reflects the values in the Enabled property, flags for the tool button, and the toUseGlyphEffects setting in ThemeServices. The following values are used in TheEffect:
          </p>
          <dl>
            <dt>gdeNormal</dt>

            <dt>gdeShadowed</dt>
            <dd>
              Images are drawn using the shadowed effect when the button or drop-down indicator is  pressed.
            </dd>
            <dt>gdeHighlighted</dt>
            <dd>
              Images are drawn using highlighting when the button is Enabled and auto-effects are used in theme services. Otherwise, the tool bar HotImages or DisabledImages are used.
            </dd>
            <dt>gdeDisabled</dt>
            <dd>

          <p>
            Normally, a button on an application tool bar is associated with a menu item in the application. When a TMenuItem instance is assigned to the property, its property values are copied into the <var>TToolButton</var> instance using the <var>CopyPropertiesFromMenuItem</var> method. If MenuItem is set to <b>Nil</b>, a free notification is performed for the tool button instance.

      <element name="TToolBar">
        <short>
          Implements an application tool bar with buttons or other visual controls.
        </short>
        <descr>
          <p>
            <var>TToolBar</var> is <var>TToolWindow</var> descendant which implements a control used to arrange and  display buttons and other controls. The buttons are used to provide direct access to features or functions in the application, much like a menu.
          </p>
          <p>
            A tool bar is normally aligned to an edge for the parent control so that it spans its width or height. The default alignment places the tool bar along the top edge of the parent control.
          </p>
          <p>
            In basic usage, TToolBar allows TToolButton instances with the same height and width to be added to the control. The buttons can be displayed as check boxes, drop downs (combo-boxes), or drop down buttons as well. The tool bar can be configured to display images and/or captions, as well as dividers (thin) or separators (dividers with extra spacing) between buttons.
          </p>
          <p>
            Other visual controls can be created using the tool bar as the parent control. These controls are resized to the width or height (depending on alignment) for the tool bar.
          </p>
          <p>
            The tool bar can be configured to wrap buttons or child controls when the controls will not fit within the dimension for the tool bar alignment. Other visual aspects can be controlled, like use of edges around the tool bar or a flat appearance.
          </p>
          <p>
            Use the Buttons property to access and maintain the tool buttons on the control. Use Controls to access other visual control types on the tool bar.
          </p>
          <p>
            Use the OnPaint event handler to perform custom drawing on the tool bar control when the Paint method is called. Use the OnPaintButton event handler to perform custom drawing for individual tool buttons on the control.
          </p>
          <p>
            TToolBar is the ancestor for the TExtendedTabToolBar in the LazControls package.

        <descr>
          <p>
            SetButtonSize is a convenience method used to assign values for the ButtonWidth and ButtonHeight properties in a single method call. It is called when a new value is assigned to the <var>ButtonWidth</var> or  <var>ButtonHeight</var> properties.
          </p>
          <p>
            For example:
          </p>
<code>
AToolbar.SetButtonSize(32, 30);
</code>
          <p>
            is equivalent to:
          </p>
<code>
AToolbar.ButtonWidth := 32;
AToolbar.ButtonHeight := 30;
</code>
          <p>
            The existing value in the property is kept when it is the same as the new value. No actions are performed in the method when neither value has been changed, or when BeginUpdate has already been called.
          </p>
          <p>
            SetButtonSize visits each of the Buttons on the control to apply the changed values to the corresponding TToolButton properties. The button might not be updated if any of the following conditions are found.
          </p>
          <p>
            For button width:
          </p>
          <ul>
            <li>The new value is 0.</li>
            <li>
              The new value is too small for the width needed in a check box or drop-down style button.
            </li>
            <li>The tool button has AutoSize enabled.</li>
            <li>The control is not derived from TToolButton.</li>
          </ul>
          <p>
            For button height:
          </p>
          <ul>
            <li>
              In horizontal toolbars the height is set by the toolbar independent of the assigned size.
            </li>
          </ul>
          <p>
            SetButtonSize calls the SetBounds method in each tool bar button to apply the values in NewButtonWidth and NewButtonHeight.

            <var>Images</var> is a <var>TCustomImageList</var> property with icon images displayed on tool buttons when they are enabled.

Use <var>HotImages</var> for the images displayed when tool buttons are enabled and hovered under the mouse cursor.
          </p>
          <p>
            The image position for a tool button is stored in the ImageIndex property in the TToolButton instance.This requires the image at a given position in the image lists to target the same button on the tool bar control.
          </p>
          <p>
            The image list should contain images which uses the sames width and height, and appropriately sized for the ButtonWidth and ButtonHeight for the tool bar. Use <var>ImagesWidth</var> to specify the size needed for tool button icons independent of the actual image size stored in the image lists.
          </p>
          <p>
            When a new image list is assigned to the property, the tool bar is redrawn.
          </p>
          <p>
            The image lists are used when the tool buttons get the current icon drawn in the Paint method.

        <descr>
          <p>
            <var>TCustomCoolBar</var> is a <var>TToolWindow</var> descendant which defines a control like the Windows Rebar control. It provides a collection of windowed controls which are displayed in movable, resizable bands.
          </p>
          <p>
            Each band (or <var>TCoolBand</var>) on the control can have a configurable sizing grip (or grabber), a bitmap, a text label, and a single windowed control. The CoolBar handles the size and position for the control when its band is moved.  Each band can have a fixed size, or can automatically re-size to the contained control. Bands can be displayed one band per line, or re-sized and positioned to fill the available width or height for the CoolBar control.
          </p>
          <p>
            A common use case is hosting multiple toolbars in an application. Separate TToolbar instance are created and configured with event handlers or actions as needed. Each toolbar is assigned as the control for a band. A perfect example is the Lazarus IDE, which uses TCoolbar to host the file, view and run toolbars in its interface.
          </p>
          <p>
            Do not create instances of TCustomCoolBar; use the TCoolBar descendant which sets the visibility for the properties in the control.

      <element name="TCoolBar">
        <short>Implements a Rebar-like control with resizable bands.</short>
        <descr>
          <p>
            TCoolBar is a TCustomCoolBar descendant which implements a control like the Windows Rebar control. It provides a collection of windowed controls which are displayed in movable, resizable bands.
          </p>
          <p>
            Each band (or <var>TCoolBand</var>) on the control can have a configurable sizing grip (or grabber), a bitmap, a text label, and a single windowed control. The CoolBar handles the size and position for the control when its band is moved.  Each band can have a fixed size, or can automatically re-size to the contained control. Bands can be displayed one band per line, or re-sized and positioned to fill the available width or height for the CoolBar control.
          </p>
          <p>
            A common use case is hosting multiple toolbars in an application. Separate TToolbar instance are created and configured with event handlers or actions as needed. Each toolbar is assigned as the Control for a band on the cool bar control. A perfect example is the Lazarus IDE, which uses TCoolbar to host the file, view and run toolbars in its interface.

            <var>TTrackBar</var>: a device which allows the user to determine the value of a variable using a quasi-analog slider.
          </p>
          <p>
            The device looks like a slider-potentiometer control on a hi-fi amplifier and consists of a slider which can be moved along a bar using the mouse. Tick marks can be displayed along one or both edges, giving an indication of the proportion of the maximum value of the controlled variable that is being selected.
          </p>
          <p>
            The <var>Position</var> property indicates the distance along the bar that the slider has been placed, either by the program or by mouse capture and movement.
          </p>
          <p>
            In the example, movement of the slider is detected and shown in the associated <link id="#lcl.comctrls.TProgressBar">TProgressBar</link>.

            The property value is calculated by calling the <var>UpdateAllTops</var> method in the TreeView control.  The value contains the accumulated <var>Height</var> for all preceding <var>TreeNodes</var> starting at the first visible node in the control, and reflects their <var>Visible</var> and <var>Expanded</var> settings. The value is calculated in UpdateAllTops when <var>tvsTopsNeedsUpdate</var> has been included in the <var>States</var> property for the TreeView control.

          <p>
            DoPaint performs the multi-stage drawing process for nodes in the tree view control using its Canvas and a display rectangle using the <var>ClientWidth</var> for the control. If the control includes event handlers for the cdPrePaint stage, the <var>CustomDraw</var> method is called.
          </p>
          <p>
            DoPaint draws the nodes on the tree view starting at the node in TopItem. If the node is Visible, the <var>DoPaintNode</var> method is called to render the tree node. The next visible node in the tree is retrieved, and the process is repeated until no more nodes are available or the drawing area is filled.
          </p>
          <p>
            An <var>InsertMark</var> is drawn for the root node if needed.

            <var>DoPaintNode</var> is a method used to render the tree node specified in <var>Node</var> to the <var>Canvas</var> for the control. DoPaintNode is called from the DoPaint method, and occurs for visible nodes processed in the method. No actions are performed in the method when the Node is not in the visible client area for the control.
          </p>
          <p>
            DoPaintNode draws the elements which represent a given tree node, including:
          </p>
          <ul>
            <li>Text for the tree node (when it is not the EditingItem for the control).</li>
            <li>An Image or State Image for the node.</li>

            DoPaintNode retrieves scaled image resolutions needed for the Images and StateImages in the control. The images sizes  are determined by applying the scaling factor in Canvas to the current Pixels Per Inch setting in Font.
          </p>
          <p>
            Use of multi-stage custom drawing is supported. If event handlers are provided for the cdPrePaint and cdPostPaint stages, the CustomDraw and CustomDrawItem methods are used to render the node with the drawing state for the node.

            <var>MouseDown</var> is an overridden method in <var>TCustomTreeView</var> used to handle mouse down events in the control.
          </p>
          <p>
            <var>Button</var> identifies the mouse button for the event.
          </p>
          <p>
            <var>Shift</var> contains the Shift, Alt, or Ctrl modifier for the mouse event.
          </p>
          <p>
            <var>X</var> and <var>Y</var> contain the coordinates for the mouse event.
          </p>
          <p>
            MouseDown updates the States property to remove the values tvsEditOnMouseUp and tvsSingleSelectOnMouseUp.
          </p>
          <p>
            The tree node for the mouse event is retrieved using GetNodeAt for the mouse coordinates. The Selected state for the tree node is saved so the selection can be restored prior to exit.
          </p>
          <p>
            MouseDown ensures that both Left and Right mouse button events are handled (when needed). When RightClickSelect is True, the Selection can be changed using the Right mouse button. Otherwise, it is ignored. Multi-selection is handled when the Shift modifier is set for the mouse event.
          </p>
          <p>
            A mouse event on an unused space in the control causes ClearSelection to be called when RowSelect is True. Selected is set to Nil if RowSelect is False.
          </p>
          <p>
            When MultiSelect has not been enabled, the selected tree node is assigned to the Selected property. When it has been enabled, the MultiSelect method in Items is used to include the selected tree node in the Selections property. ClearSelection is called if the tree node was de-selected by the mouse event. Selected is set to Nil if the tree node was de-selected by the mouse event.
          </p>
          <p>
            The control is Focused (when needed and allowed) by calling the SetFocus method.
          </p>
          <p>
            Mouse events in the Expand or Collapse indicator causes the Expanded state for the tree node to be toggled. When RowSelect is enabled, the MouseUp event causes the editor to be activated for the node.
          </p>
          <p>
            MouseDown calls the inherited method to handle drag messages or close the editor for the control.

            The Items property has additional validations performed for its property values. The ConsistencyCheck method in Items is called to verify node counts, update counts, index values, and hierarchy levels in the container. An Exception is raised for error conditions in these items as well.
          </p>
          <p>
            Values in the States property are examined and updated (when needed) to refresh the display coordinates for tree nodes, the maximum width for the expanded nodes in the control, and the levels in the tree hierarchy. These operations may also raise an Exception for invalid states or values.
          </p>
          <p>
            ConsistencyCheck is called from the WriteDebugReport method.

        <descr>
          <p>
            CustomSort is a Boolean function used to sort the tree nodes in Items using the sort procedure specified in SortProc. If SortProc is not assigned, the DefaultTreeViewSort method is used in the sort procedure.
          </p>
          <p>
            No actions are performed in the method when the number of tree nodes in Items is 0 (zero).

          <p>
            The return value is always False.
          </p>
          <p>
            CustomSort calls BeginUpdate to minimize updates during the sorting process. EndUpdates is called when the sorting process is completed.
          </p>
          <p>
            Top-level nodes in Items are sorted by calling the SortTopLevelNodes in items. Child nodes are then sorted (when present), starting at the first top-level node in the tree. The ClearCache method in Items is called to invalidate the node cache for the control.
          </p>
          <p>
            The States property is updated to force the node coordinates and scroll bars to be refreshed in the control.

          <p>
            ExpandSignType is used in the DoPaintNode method to determine the drawing style for the expand / collapse indicator for a tree node that has child nodes. It also determines the scaling mechanism needed for themed versus non-themed drawing styles.
          </p>
          <p>
            Use ExpandSignSize to set the default dimensions for the indicator before it is scaled for the theme or font size. Use  ExpandSignColor to set the fill color for a filled arrow-style indicator. Use ExpandSignWidth to set the line width used for a chevron or angle bracket-style indicator.

          </p>
          <p>
            When a tree node is selected or unselected, the Selected property in the TTreeNode instance is updated.

          <p>
            Selecting a tree node forces it to become fully visible in the control. This includes expanding parent nodes to ensure that the node is visible.  The <var>OnExpanding</var> and <var>OnExpanded</var> event handlers are signalled before and after actions to a given tree node.

The RegisterChanges method in the image list is called after the new images are assigned. The value in DefaultItemHeight is updated (when needed) to use the height for the images scaled to the current PPI setting in Font. The item height will include the default item spacing needed for the images. The control is redrawn when the new image list has been assigned to the property.

            <var>THeaderSection</var> is a <var>TCollectionItem</var> descendant which implements a section displayed on a <var>TCustomHeaderControl</var> / <var>THeaderControl</var> instance.

          </p>
          <p>
            THeaderSection has properties which identify its visual characteristics. This includes the text displayed for the section, its alignment, minimum and maximum widths, and an index for an optional image. Other properties contain run-time information about the section, including its left and right coordinates and its display state.
          </p>
          <p>
            THeaderSection instances are normally created at design-time and edited using the IDE object inspector. They can be created at run-time using methods in the THeaderSections collection, and edited in code.

The value in its <var>State</var> property is used to render the section by calling methods in ThemeServices. When Images have been assigned in the control, and the header section  has an assigned image index, it is drawn to the Canvas.  When Text contains a non-empty value, it is also rendered to the Canvas using the DrawText method in ThemeServices.

            <var>ChangeScale</var> is an overridden method in TCustomHeaderControl, and calls the inherited method on entry to scale the overall size for the control and its child controls. ChangeScale applies the scaling factor represented by M and D to the individual header sections defined in the Sections collection. The Width for each THeaderSection instance is updated using the multiplier and divisor to scale the section width.

            <var>THeaderControl</var>, a header strip of user-designed sections which allow selection of pages or actions.
          </p>
          <p>
            <var>THeaderControl</var> offers a widget that could be placed along the edge of a <var>Panel</var> or <var>Form</var> allowing a highly customized mechanism for selection. However there are no intrinsically associated display areas and it is the developer's responsibility to supply an index associated with the selection from the <var>THeaderControl</var> and determine what action is to occur or what is to be displayed in any attached Panel or Form.
          </p>
          <p>
            THeaderControl is used by selecting its icon from the Common Controls tab of the IDE Component Palette and placing it on the Form in the desired position. It may be convenient to dock it with a <var>Form</var> or <var>Panel</var> whose properties it is to be used for controlling.
          </p>
          <p>
            After size, position, docking, alignment, anchoring etc have been performed using the Object Inspector or Form Designer, the Sections of the Header can be created by selecting the control, right-clicking with the mouse and choosing 'Section Editor'. A Stringlist editor will pop up with options to add, delete or move entries up or down the list. Each entry is given an Index which can be used in OnClick event handlers to determine the action to be taken when that section is selected at run-time.
