          <p>
            The actual meaning of each value depends on the platform:
          </p>
          <dl>
            <dt>Windows and Mac OS X</dt>
            <dd>These operating systems support all values.</dd>
            <dt>X11</dt>
            <dd>
              The window state is a hint sent to the Window Manager, so more primitive Window Managers might ignore these hints.
            </dd>
            <dt>Windows CE</dt>
            <dd>
              In Windows CE platforms where Application.ApplicationType = atKeyPadDevice or atPDA (like in Windows Phone, PocketPC and Windows Mobile), wsMinimized and wsNormal are understood as wsMaximized, which is the normal state for windows in this platform. An exception are windows with BorderStyle=bsDialog or bsNone, which are allowed to have a custom position and size.

        <short>
          The window appears maximized. The exact behavior is up to the window manager, but usually the window appear occupying all of the work area of a monitor.
        </short>
      </element>
      <element name="TWindowState.wsFullScreen">
        <short>
          The window appears in full screen mode, when allowed by the platform. It will, for example, attempt to appear on the top of taskbars and other static platform user interface elements. wsFullScreen is converted to wsMaximized for use on the the Windows platform; the API does not provide a full screen option.

        <short>Scroll bar type used in TScrollingWinControl.</short>
        <descr>
          <p>
            Scrollable controls supply their own <b>integrated</b> scroll bars, one for horizontal and one for vertical scrolling. This class allows access to (one of) these integrated scroll bars.
          </p>
          <p>
            A scrollable control has both a physical (visible) client size, and a logical (virtual) client size.
          </p>
          <p>
            The <var>Range</var> property reflects the total virtual client size, in pixels.
          </p>
          <p>
            The <var>Page</var> property corresponds to physical (visible) client size, in pixels, excluding the scroll bars. It also determines the size of the slider, relative to the total Range.
          </p>
          <p>
            The <var>Position</var> property reflects the virtual origin of the visible client area, equivalent to the top coordinate of the slider. The Position can be changed by the user or by code.
          </p>
          <p>
            Scroll bars usually appear only when Range is higher than Page, i.e. when the entire content cannot be shown at the same time. See the scroll bar properties in <var>TScrollingWinControl</var> for more details.

            <var>ScrollHandler</var> is a method used to ensure that the control message in <var>Message</var> is applied to the <var>Position</var> property for the scroll bar. ScrollHandler uses the <var>ScrollCode</var> member from the <var>TLMScroll</var> instance to determine the actions needed in the method. It handles the following ScrollCode values:

          <p>
            ScrollHandler ensures the the new value for the Position property is in the range <b>0..<var>Range</var></b>. Calls <var>InvalidateScrollInfo</var> to force scroll bar information to be re-initialized. Calls <var>SetPosition</var> to apply the new value for the Position property and scrolls the associated <var>TScrollingWinControl</var> accordingly. Sets the <var>Result</var> member in Message to <b>1</b> to indicate the control message was handled in the method.
          </p>
          <p>
            ScrollHandler is called when the <var>WMHScroll</var> or <var>WMVScroll</var> methods in the associated TScrollingWinControl instance are used to handle scroll messages.

        <descr>
          <p>
            <var>TCustomFrame</var> is a <var>TCustomDesignControl</var> descendant which implements the base class for <var>TFrame</var>.  A Frame is a named container for related components. Groups of  controls can be place on a frame, and re-used in your applications.
          </p>
          <p>
            A Frame has behavior very similar to a Form. Their unique ability is that they can be embedded into forms or other frames in the designer.  Like forms, they are stored in two separate files: the code is stored in a .pas unit file, and the design is stored in a .lfm file.
          </p>
          <p>
            Frames can be created and designed in the Lazarus IDE by creating a new Frame module, and using the unit in your application. An existing frame can be added using the TFrame component on the Standard tab in the Lazarus IDE; you will be prompted for the TFrame class to use for the component.
          </p>
          <p>
            Frames can also be created entirely in code at run-time. They do not have to be installed in the Lazarus IDE. One drawback is that complex inheritance hierarchies for <var>TFrame</var> classes can be problematic; they do not propagate changes to all derived frames in a multi-level inheritance tree.

      <element name="TFrame">
        <short>
          Frames can be designed like Forms and used like custom controls, without much coding or installation in the IDE.
        </short>
        <descr>
          <p>
            <var>TFrame</var> is a <var>TCustomFrame</var> descendant which implements a named container for related components. Groups of  controls can be place on a frame, and re-used in your applications.
          </p>
          <p>
            A Frame has behavior very similar to a Form. Their unique ability is that they can be embedded into forms or other frames in the designer.  Like forms, they are stored in two separate files: the code is stored in a .pas unit file, and the design is stored in a .lfm file.
          </p>
          <p>
            Frames can be created and designed in the Lazarus IDE by creating a new Frame module, and using the unit in your application. An existing frame can be added using the TFrame component on the Standard tab in the Lazarus IDE; you will be prompted for the TFrame class to use for the component.
          </p>
          <p>
            Frames can also be created entirely in code at run-time. They do not have to be installed in the Lazarus IDE. One drawback is that complex inheritance hierarchies for <var>TFrame</var> classes can be problematic; they do not propagate changes to all derived frames in the entire inheritance tree.
          </p>
          <p>
            TFrame contains a new property which indicates the LCL (Lazarus Component Library) version number used in the container. An overridden constructor is also introduced to initialize the value in the LCLVersion property. TFrame sets the visibility for properties defines in ancestor classes.

            Forms represent a window or a dialog used as the user interface for a GUI application. It is a container where visual components (such as buttons, labels, edit fields, images, etc.) can be placed. It is also a designer surface which provides design-time support for configuration and layout of the content placed on the form.

          <p>
            <var>TCustomForm</var> acts an abstraction layer which masks implementation-specific routines required for the various widgetsets supported in the Lazarus Component Library (<b>LCL</b>). Methods and properties are provided which interact with the underlying Operating System or platform, and provide a common API for form-related operations.

          <p>
            CloseModal calls <var>CloseQuery</var> to determine the action performed in the method. When CloseQuery returns <b>True</b>, the close action is set to <var>caHide</var> and the <var>OnClose</var> event handler is signalled when assigned. Form handlers are notified of the close action.
          </p>
          <p>
            When CloseQuery is <b>False</b>, the close action is used to determine how the request is handled. If the CloseAction is <var>caNone</var>, the value in <var>ModalResult</var> is set to <b>0</b> (<b>zero</b>). If the CloseAction is <var>caFree</var>, the <var>Release</var> method is called to allow the <var>Application</var> to free the form component.

        <descr>
          <p>
            <var>AddHandler</var> is a procedure used to add a form notification handler to the list of handlers in the form instance.
          </p>
          <p>
            <var>HandlerType</var> is a <var>TFormHandlerType</var> enumeration value that defines the situation(s) where the form handler can be executed. See <link id="TFormHandlerType">TFormHandlerType</link> for more information about values in the enumeration.
          </p>
          <p>
            <var>Handler</var> is a <var>TMethod</var> record with pointers to the code and optional data executed when the handler is invoked.
          </p>
          <p>
            <var>AsFirst</var> indicates if the handler should be inserted as the initial handler in the method list (when <b>True</b>), or appended to the end of the list (when <b>False</b>).
          </p>
          <p>
            AddHandler calls <var>RaiseGDBException</var> to raise an exception when the pointer to the Code in Handler has not been assigned.
          </p>
          <p>
            AddHandler ensures that a <var>TMethodList</var> exists for handlers using the value in HandlerType, and calls the <var>Add</var> method in the <var>TMethodList</var> to store the Handler at the position needed for AsFirst.
          </p>
          <p>
            AddHandler is called from the implementation of more specialized methods like <var>AddHandlerClose</var>, <var>AddHandlerCreate</var>, and <var>AddHandlerFirstShow</var>.

            MoveToDefaultPosition gets the display rectangle for the form instance. Its dimensions and coordinates are translated to the Monitor and/or relative layout indicated in <var>Position</var>. <var>SetBounds</var> is called to apply the

            When <var>Visible</var> is set to <b>True</b> at run-time, the <var>MoveToDefaultPosition</var> method is called to move the form to the monitor / location in the <var>Position</var> property. This action is not needed (or allowed) at design-time. When <var>FormState</var> indicates it is the first time the form is being displayed, the <var>DoFirstShow</var> method is called to notify event handlers for the form.
          </p>
          <p>
            UpdateShowing calls the inherited method to update the <var>Handle</var> for the form and the visibility for any child <var>Controls</var>.

          <p>
            If <var>ActiveControl</var> is not  assigned, and there is no <var>Parent</var> form, the <var>FindDefaultForActiveControl</var> method is called to locate the first visible and enabled child control on the form. Its Handle is used to focus the control using the LCL <var>SetFocus</var> routine.
          </p>
          <p>
            Finally, the visibility of the form in the task bar is updated and passed to the widgetset class.

            <var>DoDock</var> is an overridden method used to dock / undock the form instance in the dock site specified in <var>NewDockSite</var>. When NewDockSite is unassigned (contains <b>Nil</b>), the form instance is undocked from the host dock site.

          <p>
            When a form is docked, its <var>BorderStyle</var> is set to <var>bsNone</var>. DoDock ensures that the value in the BorderStyle property is saved or restored for the form when the value in <var>HostDockSite</var> is changed. If NewDockSite has been assigned, the value in BorderStyle is saved to an internal member. If NewDockSite is Nil,  the value in BorderStyle is restored from the internal member.

            Changes needed for the <var>Align</var> property must be handled in the DockManager.

            AutoScale uses the value in the <var>PixelsPerInch</var> property for the <var>Monitor</var> where the form is displayed to determine if the form and its controls need to be scaled. When Scaled is enabled for the <var>Application</var>, and the run-time PixelsPerInch setting differs from the design-time value, the <var>AutoAdjustLayout</var> method is called.

            The <var>SetActive</var> method is used to update the value for the property, locate an <var>ActiveControl</var> for the form, and give focus to the form control. SetActive is called from the <var>WMActivate</var> method when the <var>LM_ACTIVATE</var> window control message is handled for the form.

            <var>MDIChildren</var> is a read-only indexed <var>TCustomForm</var> property which provides access to the child forms in a Multi-Document Interface (MDI) application. In an MDI application, one of the forms acts as the main form for the application, and is the container for its MDI child forms. In addition, an MDI child form can be nested in another MDI child form.
          </p>
          <remark>
            Historically, support for MDI is dependent on the underlying widgetset or platform. Some widgetsets provide better support for MDI than others. The consensus is that the QT/QT5  widgetsets offers the best level of support for MDI applications.
          </remark>
          <p>
            The form role is determined by the value in the <var>FormStyle</var> property. <var>fsMDIForm</var> is used for the main form, and <var>fsMDIChild</var> for the child forms. <var>MDIChildren</var> is relevant when the current form instance uses one of these MDI form style values.

          <p>
            <var>Index</var> is an <var>Integer</var> value is used to access a MDI child form by its ordinal position in MDIChildren. The return value contains the <var>TCustomForm</var> instance at the specified position, as determined using the <var>GetMDIChildren</var> method in the widgetset class. The return value can be <b>Nil</b> when the current form does not use a FormStyle with the value fsMDIForm or fsMDIChild, or when a handle has not yet been allocated for the form instance. The return value is always <b>Nil</b> at design-time.

            DoAddDockClient is an overridden method used to add the control in Client to the docked form.

It sets the Align property in Client to alAlign to align the control to the bounds for the docked form. Values in the BorderSpacing property in Client are reset to 0; the current class instance provides the BorderSpacing values for the docked control. At run-time, the Visible property is set to True to display the docked form after the Client has been added.

        <short>
          Adds a handler routine to the list for the specified handler type.
        </short>
        <descr>
          <p>
            <var>AddHandler</var> is a procedure used to add a screen notification handler to the list of handlers in the TScreen instance.
          </p>
          <p>
            <var>HandlerType</var> is a <var>TScreenNotification</var> enumeration value that defines the situation(s) where the screen  handler can be executed. See TScreenNotification for more information about values in the enumeration.
          </p>
          <p>
            <var>Handler</var> is a <var>TMethod</var> record with pointers to the code and optional data executed when the handler is invoked.
          </p>
          <p>
            <var>AsFirst</var> indicates if the handler should be inserted as the initial handler in the method list (when <b>True</b>), or appended to the end of the list (when <b>False</b>).
          </p>
          <p>
            AddHandler calls <var>RaiseGDBException</var> to raise an exception when the pointer to the Code in Handler has not been assigned.
          </p>
          <p>
            AddHandler ensures that a <var>TMethodList</var> exists for handlers using the value in HandlerType, and calls the <var>Add</var> method in the <var>TMethodList</var> to store the Handler at the position needed for AsFirst.
          </p>
          <p>
            AddHandler is called from the implementation of more specialized methods like AddHandlerFormAdded, AddHandlerRemoveForm, AddHandlerActiveControlChanged, AddHandlerActiveFormChanged, and AddHandlerFormVisibleChanged.

        <short>
          Adds an application notification handler to the list of handlers for the specified type.
        </short>
        <descr>
          <p>
            <var>AddHandler</var> is a procedure used to add an application notification handler to the list of handlers in the TApplication instance.
          </p>
          <p>
            <var>HandlerType</var> is a <var>TApplicationHandlerType</var> enumeration value that defines the situation(s) where the handler can be executed. See TApplicationHandlerType for more information about values in the enumeration.
          </p>
          <p>
            <var>Handler</var> is a <var>TMethod</var> record with pointers to the code and optional data executed when the handler is invoked.
          </p>
          <p>
            <var>AsFirst</var> indicates if the handler should be inserted as the initial handler in the method list (when <b>True</b>), or appended to the end of the list (when <b>False</b>).
          </p>
          <p>
            AddHandler calls <var>RaiseGDBException</var> to raise an exception when the pointer to the Code in Handler has not been assigned.
          </p>
          <p>
            AddHandler ensures that a <var>TMethodList</var> exists for handlers using the value in HandlerType, and calls the <var>Add</var> method in the <var>TMethodList</var> to store the Handler at the position needed for AsFirst.
          </p>
          <p>
            AddHandler is called from the implementation of methods specialized for a specific application handler type, like:

            <var>Notification</var> is an overridden method in <var>TApplication</var> used to perform actions needed when a component is added to or removed from the application. Notification provides special handling when component references are removed. It ensures that the internal member for a given component is set to <var>Nil</var> when the reference is freed. If the freed component is the MainForm for the application, the Terminate method is called to shut down the application and update the OS-level ExitCode.

          <p>
            Idle is a method used to perform actions when the application enters an idle state. It allows the application to free components pending release, and handle any queued asynchronous requests.
          </p>
          <p>
            In addition, Idle calls event and application handlers assigned in the class instance. OnIdle is signalled (when assigned). NotifyIdleHandler is called to signal any application handler(s) using the ahtIdle handler type.
          </p>
          <p>
            The DoIdleActions method is called to update the actions for Visible and Enabled forms, and to hide visible splash screen forms (FormStyle is fsSplash).
          </p>
          <p>
            When the Wait argument is set to True, the AppWaitMessage method in the widgetset class is called to capture an message on the handles for the application. This action is not performed when Wait is False.
          </p>
          <p>
            Idle calls the DoOnIdleEnd method to signal the OnIdleEnd event handler and any application handlers using the ahtIdleEnd handler type.

        <descr>
          <p>
            <var>E</var> is the Exception instance with the message displayed in the method. If the message contains an invalid UTF-8 codepoint, AnsiToUtf8 is called to get a valid UTF-8 value for the exception message.
          </p>
          <p>
            ShowException creates a dialog to display the exception message. If the exception occurred before the application was fully initialized, the inherited ShowException method is called.
          </p>
          <p>
            The value in the ExceptionDialog property determines the type of dialog displayed for the message, and the buttons available on the dialog. While the dialog is active, the OnIdle event handlers in the application are disabled. They are re-enabled when the dialog is closed. The modal result from the dialog determines whether the application is terminated by calling Halt, or allowed to continue.
          </p>
          <remark>
            No actions are performed in the method when AppNoExceptionMessages has been included in the Flags for the application. The exception message is not displayed and control is returned to the calling routine.

            Double buffering is a technique used to reduce screen flickering when form and controls are (re)drawn. When enabled, an off-screen buffer is used to accelerate drawing operations.
          </p>
          <p>
            The default value for the property is adbDefault and indicates that the application uses the default capabilities provided by the widgetset.

          <remark>
            DoubleBuffered is a platform-specific property. Only the Windows platform implements double buffering (at the widgetset level) in the current LCL version. Changing the value for the property to True has no effect if double buffering is not implemented for the widgetset used in the Application.

        <short>
          Controls whether a button is displayed on the task bar for the main form in the application.
        </short>
        <descr>
          <p>
            <var>MainFormOnTaskBar</var> is a <var>Boolean</var> property which determines whether the icon for the main form in the application is displayed on the task bar. When MainFormOnTaskBar is set to <b>True</b>, a button representing the main form is displayed on the task bar area in the window manager. When set to <b>False</b>, the button is not displayed in the task bar area.
          </p>
          <p>
            Changing the value in the property causes the Widgetset class to be notified of the new property value.
          </p>
          <p>
            MainFormOnTaskBar is a platform-dependent property. It may not be implemented for all platforms supported for the Lazarus application. In addition, some platforms which display task bar thumbnails (like Windows Vista) may require the property to be set to True.
          </p>
          <p>
            The default value for the property is normally set in the Lazarus project file (<b>.lpr</b>) used to compile the application.

            <var>Scaled</var> is a <var>Boolean</var> property which indicates if the application can be scaled between differing display densities (Pixels per Inch) at run-time.

          <p>
            When Scaled is set to <b>True</b>,  the application allows the design-time PixelsPerInch value to be adjusted to reflect the run-time value. Forms, frames, image lists, and other controls also have a Scaled property which determines if the feature is enabled for that particular class type. If Scaled is set to <b>False</b> in TApplication, the feature is disabled for all of the other class types. Scaled (at the application-level) is normally checked before the component- or control-level setting.

      <element name="RequireDerivedFormResource">
        <short>
          When True every form must have a resource (e.g. a .res file). An exception is raised if the resource is missing when creating a form.
        </short>
        <descr>
          <p>
            The form resource is the <file>.lfm</file> file compiled into the executable of your application. For this flag, it does not matter if it was compiled via an <file>.lrs</file> file or via <file>fpcres</file>. The resource is automatically loaded by <var>TForm</var> and its descendants when created using the   <var>Create(Owner)</var> method.
          </p>
          <p>
            If the resource file is missing, there is something wrong with either a resource or the unit which contains the faulty form. If the flag is False, you will see a blank form and probably search a long time what is wrong. If you set this flag to True, you get an exception.
          </p>
          <p>
            For creating forms without resources, you have 3 options:
          </p>
          <ul>
            <li>Create a TForm class (not a descendant).</li>
            <li>Construct your form using the CreateNew() constructor.</li>
            <li>It is also possible to disable the exception by setting the global
               variable RequireDerivedFormResource to False.</li>
          </ul>
          <p>
            History:
            Before 0.9.31 there was no exception. Therefore some resource-less forms
            might use the standard constructor Create(Owner) and will now get
            exceptions. This change is Delphi compatible and compatible with
            TFrame and TDataModule components.
