            <var>Move</var> is an overridden procedure in <var>TUNBPages</var>.  It re-implements the method defined in the <var>TStrings</var> ancestor class. Move is used to relocate the active page in a NoteBook control to a new position in the page list.
          </p>
          <p>
            Move uses the internal <var>TNotebook</var> member that is the owner of the class instance to retrieve the current page and its ordinal position.
          </p>
          <p>
            <var>CurIndex</var> is set to the <var>PageIndex</var> for the active page in the Notebook component. <var>NewIndex</var> specifies the new ordinal position in the page list for the <var>TPage</var> instance.
          </p>
          <p>
            The Move method in the internal page list (TObjectList) is called to move the TPage instance from using the required positions. The PageIndex for the TNotebook control is reset to re-activate the page moved in the operation.
          </p>
          <remark>
            Move does <b>NOT</b> call the inherited method.

          <p>
            <var>TNotebook</var> is a control which can hold a series of pages placed together. Only one page is shown at a time and this control is completely custom drawn, which means that it is available and looks the same in any widgetset which supports TCustomControl. The pages are containers which can hold controls. This control never has tabs. If you are looking for a control with tabs and pages, please see <var>TPageControl</var> instead.
          </p>
          <p>
            To use a Notebook, select its icon from the 'Additional' tab of the Component Palette and place it on the Form. Adjust its size, position, alignment and anchoring as required, by moving the object on the Form or by using the Object Inspector.
          </p>
          <p>
            Pages are added to the NoteBook by selecting the control and right-clicking with the mouse to get a pop-up menu whose first item is 'Add Page'. Pages already in the NoteBook can be edited by selecting the appropriate ActivePage in the Object Inspector and modifying its properties or adding additional components to that Page.

            <var>Paint</var> is an overridden procedure used to draw the shape for the control on its <var>Canvas</var>. Paint uses the <var>Pen</var>, <var>Brush</var>, and <var>Shape</var> defined in the control. Drawing methods in Canvas are called to render the desired Shape to a rectangle using the Width and Height defined in the component.
          </p>
          <p>
            Paint calls the inherited Paint method to signal an OnPaint event handler assigned in the class instance.

            <var>TCustomSplitter</var> is a <var>TCustomControl</var> descendant which implements a control used to resize, position and align a control to which it is anchored. TCustomSplitter displays a vertical or a horizontal bar anchored to the side of another control. Use the <var>Align</var> property to specify the orientation for the splitter control, and the adjacent control to which it is attached. When the splitter is moved with the mouse, the adjacent control with the same Align value will be resized.
          </p>
          <p>
            This class defines many of the basic properties for the children classes, such as positioning, sizing and alignment.

            <var>Paint</var> is an overridden procedure used to draw the image to the control <var>Canvas</var>. At design-time, a dashed black line is drawn around the image as a frame to mark the dimensions for its content.

         <p>
           Paint uses the Canvas from the ancestor class as the target for the drawing operation. The value in <var>AntialiasingMode</var> is assigned to the corresponding property in the Canvas. The rectangle returned from    <var>DestRect</var> is used as the drawing area.
         </p>
         <p>
           Paint signals the <var>OnPaintBackground</var> event handler (when assigned) using the canvas and drawing rectangle to render the background for the image. The <var>StretchDraw</var> method in the Canvas is used to render the image content.
         </p>
         <p>
           Paint calls the inherited method to ensure that the <var>OnPaint</var> event handler is signalled (when assigned).

          <p>
            Invalidate extends the ancestor method to include logic that reduces the number of calls to the <var>Paint</var> method, and avoids flicker caused by the redundant calls. It uses an internal flag in the class to determine if the Paint method has already been called, but has not yet been completed. If the flag has not been set, the inherited Invalidate method is called to refresh the control using its visibility and control style settings.

        <descr>
          <p>
            The <var>Visible</var> property represents the ability to see a visual control. If Visible is <b>True</b> the control is shown, otherwise it is hidden. Calling <var>Show</var> sets Visible to <b>True</b>. Setting Visible to <b>False</b> is equivalent to calling <var>Hide</var> method.
          </p>
          <remark>
            The Visible property does not depend on control's parent visibility. Use the <var>IsVisible</var> method to consider this and get the real visibility for the control.

        </short>
        <descr>
          <p>
            <var>ItemIndex</var> is an <var>Integer</var> property with the ordinal position for the selected radio button in the group. It refers to the position in <var>Items</var> with the caption for the radio button. The default value for the property is <b>-1</b>, and indicates that a radio button is not selected for the group.
          </p>
          <p>
            ItemIndex must be in the range <b>-1..<var>Items.Count</var>-1</b>. An Exception is raised with the message in rsIndexOutOfBounds if an invalid value is used.
          </p>
          <p>
            When the value for the property is changed, the OnClick event handler is signalled (when assigned). In addition, the OnSelectionChanged is signalled (when assigned). Both events occur even if the Handle has not been allocated in the widgetset class. This is Delphi compatible.
          </p>
          <p>
            Use the OnItemEnter and OnItemExit event handlers to perform actions when the focus or selection for a radio button is changed, as opposed to a change in the properties for the group control.
          </p>
          <remark>
            Some widgetsets do not allow a radio button group to be unselected, or have no selected radio button. For this reason, a hidden radio button exists in TCustomRadioGroup and is selected when ItemIndex is set to -1.

            <var>TRadioGroup</var>: A group of related but mutually exclusive radio buttons, requiring the user to select one of a set of alternatives. As one button becomes selected, the remaining buttons in the group become automatically deselected.
          </p>
          <p>
            To Use this control, place it in the required position on the form, then in the Object Inspector select <var>Items</var> and click on the ellipsis (...) to open the string editor. Type in the captions to accompany each check box, then close the string editor and you will see a series of Radio Boxes with their captions displayed beside them. (Note - unlike <link id="#lcl.ExtCtrls.TCheckGroup">TCheckGroup</link>, there is no special RadioGroup editor).

            <var>TRadioGroup</var> behaves differently from a group of <var>TRadioButton</var> controls placed arbitrarily around a form.
          </p>
          <p>
            In the case of <var>TRadioButton</var>, the mutual exclusivity is a feature that applies to any <var>RadioButton</var> anywhere in the Form, and the <var>RadioButtons</var> can be rearranged in any order or placed anywhere within the containing <var>Form</var>, while in <var>TRadioGroup</var> the exclusivity applies only to buttons within the Group, which are ordered strictly according to their <var>ItemIndex</var> within the <var>Items</var> stringlist.
          </p>
          <p>
            <var>TRadioButton</var> is an entity in itself, with a number of additional properties, whereas the buttons within <var>TRadioGroup</var>  are not separate entities, but rather are simply entries in a list of strings, each of which is associated with the on-screen image of a <var>RadioButton</var>.
          </p>
          <p>
            The example shows the difference between the use of <var>TRadioButton</var> and <var>TRadioGroup</var>.

        <short>
          Defines the base class for a multi-platform system tray icon component.
        </short>
        <descr>
          <p>
            <var>TCustomTrayIcon </var> is the base class for <var>TTrayIcon</var>, a multi-platform system tray icon component. It allows an icon to be displayed in the system tray when the Application or Form is active. TCustomTrayIcon provides properties, methods, and events used to configure, display, and control the tray icon. The component is supported on multiple platforms, but its implementation is platform-specific.
          </p>
          <p>
            On the Windows platform, the system tray is usually located on the bottom-right corner of the screen, but it can be located on other edges for the physical screen. For other platforms, the position and other features varies according to the window or display manager in use.
          </p>
          <p>
            Use Icon to set the icon image type displayed for the control. Use Icons to assign a list of images displayed as the animated icon for the control when the Show method is called.
          </p>
          <p>
            Use BalloonFlags, BalloonHint, BalloonTimeout and BalloonTitle to format and display balloon hints for the tray icon. If balloon hints are not supported for the platform, an internal TPopupNotifier is used to display the Hint for the control.
          </p>
          <p>
            Use PopUpMenu to set the menu displayed when the icon is right clicked with the mouse.
          </p>
          <p>
            Assign routines to the event handlers to perform actions needed when the icon is clicked - or when mouse move, up, or down messages are received.
          </p>
          <remark>
            TCustomTrayIcon / TTrayIcon are <b>partially</b> compatible with the Delphi VCL component. It adds an OnPaint event handler which does not exist in Delphi. It omits properties like IconIndex and OnBalloonClick.

            The behavior of this method depends on the widgetset.It was added to provide a way to update items which either cannot be updated automatically when changed, or would be too inefficient to be updated on each change.
          </p>
          <p>
            One example of this is the tray icon menu under LCL-Carbon. It is not automatically updated when changes are made to it's associated LCL TPopUpMenu, but changes are updated when InternalUpdate is called. This happens because the tray icon menus are Cocoa menus which don't match the Carbon menus from LCL-Carbon.
          </p>
          <p>
            Similar things happen in other widgetsets, so InternalUpdate can be expected to update the menu and/or icon of the tray icon, if this is necessary. If such an update is not required, for example because it is automatically updated on each change, then InternalUpdate will simply do nothing, so it is always a safe function to call, regardless of the widgetset.

      <element name="TTrayIcon">
        <short>
          Implements a multi-platform system tray component.
        </short>
        <descr>
          <p>
            <var>TTrayIcon</var> is a <var>TCustomTrayIcon</var> descendant which implements a multi-platform System Tray component. It allows an icon to be displayed in the system tray when the Application or Form is active. TTrayIcon provides properties, methods, and events used to configure, display, and control the tray icon. It sets the visibility for properties from ancestor classes. The component is supported on multiple platforms, but its implementation is platform-specific.
          </p>
          <p>
            On the Windows platform, the system tray is usually located on the bottom-right corner of the screen, but it can be located on other edges for the physical screen. For other platforms, the position and other features varies according to the window or display manager in use.
          </p>
          <p>
            Use Icon to set the icon image type displayed for the control. Use Icons to assign a list of images displayed as the animated icon for the control when the Show method is called.
          </p>
          <p>
            Use BalloonFlags, BalloonHint, BalloonTimeout and BalloonTitle to format and display balloon hints for the tray icon. If balloon hints are not supported for the platform, an internal TPopupNotifier is used to display the Hint for the control.
          </p>
          <p>
            Use PopUpMenu to set the menu displayed when the icon is right clicked with the mouse.
          </p>
          <p>
            Assign routines to the event handlers to perform actions needed when the icon is clicked - or when mouse move, up, or down messages are received.
          </p>
          <remark>
            TCustomTrayIcon / TTrayIcon are <b>partially</b> compatible with the Delphi VCL component. It adds an OnPaint event handler which does not exist in Delphi. It omits properties like IconIndex and OnBalloonClick.

            <var>MultiPageControls</var> - controls that offer a selection of alternative pages for display.
          </p>
          <p>
            A number of controls, found in Units <var>ExtCtrls</var> and <var>ComCtrls</var>, offer the ability to create multi-page forms with a series of <var>Tabs</var> along one edge that allow the user to select one of the <var>Pages</var> for display and interaction.
          </p>
          <p>
            These include: <var>TPageControl</var>, <var>TNoteBook</var>, <var>TTabControl</var> and <var>THeaderControl</var> (the Header Control components have a very different structure and function). Icons for all of these exist on the <var>Additional</var> or <var>Common Controls</var> tabs of the Component Palette in the Lazarus IDE.
          </p>
          <p>
            While the various components may look superficially similar, they differ in properties, inheritance, method of adding additional pages, behavior at run-time, methods for referencing pages and so on.
          </p>
          <p>
            We have to be very clear when using the various properties, to distinguish between the word 'Tab' as referring to a Tab indicating an identifier for a page, and 'Tab' as referring to the <b>TAB</b> key on the standard keyboard. In common with most Lazarus components, it is possible to enable each control to be included in the <var>TabOrder</var> of <var>TabStops</var> for a <var>Form</var>, so that the component can be reached by repeated pressing of the <b>TAB</b> key, and we must not confuse this use of 'Tab' with the use to denote a <var>Page</var>.
          </p>
          <p>
            The properties <var>CanTab</var>, <var>TabStop</var> and <var>TabOrder</var> refer to the use of the <b>TAB</b> key to navigate to the relevant control.

            Properties such as <var>Tabs</var>, <var>TabIndex</var>, <var>IndexOfTabAt()</var>, <var>TabIndexAtClientPos()</var>,  <var>TabPosition</var>, <var>TabHeight</var>, <var>TabWidth</var>, <var>TabVisible</var>, <var>OnCloseTabClicked</var> refer to the use for <var>Page</var> selection.

            <var>TTabControl</var> and <var>TPageControl</var> are both descended from <var>TCustomNoteBook</var> (which is in turn descended from <var>TWinControl</var>) and have many inherited properties in common. <var>TPageControl</var> has, in general, more advanced features and is probably intended to replace <var>TNoteBook</var>.

              The following table summarizes the main differences between the two components.

              <td>
                No published <var>Options</var> property, but inherits <var>Options</var> (public property) from <var>TCustomNoteBook</var>, so they could be set explicitly in code

          </table>
          <p>
            The individual Pages in both of the above controls (descended from <var>TCustomNoteBook</var>) are separate and can have their own specific collections of widgets which appear only when the relevant Page is selected by its Tab.
          </p>
          <p>
            In contrast, the <var>TTabControl</var> component (descended from <var>TCustomTabControl</var>) has only one display area (Protected property <var>DisplayRect</var>), but the image displayed in it is determined by which tab has been selected. Each Tab has an index value which is used to select the appropriate image from an indexed <var>ImageList</var> and display it in the Display Rectangle.
          </p>
          <p>
            The properties of the Tabs in <var>TTabControl</var> are very configurable compared with those in the controls derived from <var>TCustomNoteBook</var>, allowing for instance the creation of multi-line captions, the placement of images on Tabs, the possibility of the Owner routine determining the drawing of the tab, the configuration of Tab size, the selection of multiple tabs. The trade-off is that the display area is restricted in what it can display, and is essentially confined to display of images.
          </p>
          <p>
            To use any of the above controls, select them from the relevant tab on the IDE Component Palette and drop them on the form in the required position. Fill in as many relevant properties as you can in the Object Inspector.
          </p>
          <p>
            To add Tabs or Pages to the controls, select the control with a left mouse click or by selecting from the Component menu in the Object Inspector, then right-click on the component to get a pop-up menu, whose first item will be 'Add Page' or 'Add Tab'.
          </p>
          <p>
            The Tabs in <var>TTabControl</var> can be edited by selecting 'Tabs' in the Object Inspector, clicking on the ellipsis (...) and using the string editor that pops up.
          </p>
          <p>
            The pages in<var>TNoteBook</var> or <var>TPageControl</var> can be edited by selecting the <var>ActivePage</var> in the Object Inspector and then editing the properties of the individual page.
          </p>
          <p>
            <var>THeaderControl</var> offers a widget that could be placed along the edge of a Panel or Form, 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 determining what action is to occur or what is to be displayed in any attached Panel or Form.
          </p>
          <p>
            When the control is first selected from the Component Palette and placed on  a Form, it consists of an unadorned rectangle. However, selecting the control and right-clicking (or selecting the 'Sections' property in the Object Inspector) gives access to a Sections editor (a StringList editor) and Sections can be added to the control. The sections are separated by vertical lines, and each section can have a string inserted as a label, associated with an Index value. The Sections can be rearranged, re-ordered, or be individually painted.
          </p>
          <p>
            In a typical application a <var>THeaderControl</var> and a <var>TPanel</var> or <var>TForm</var> would be docked together, and code would be written to find which Section of the Header had been selected, then use its index to control the display in the other docked control.
