ActionComponent¶: Indicates the client component that caused this action to execute.

CustomText¶

CustomText is a user text. Some actions can, by default, automatically set the Text property. For example, in the TFileExit standard action, the Text property has the Quit <Application.Title> value. To set your own value, set the value of the Text property to the value of the CustomText property.

Type:: str

Execute()¶: Generates an OnExecute event.

HandlesTarget(Target: Object) → bool¶

Whether Target is appropriate for the action (True) or not (False). HandlesTarget ignores the specified Target parameter, actually. Regardless of the specified target, HandlesTarget returns True provided that:

The platform where your application is running supports this action. Your action does not have any event handler assigned to its OnExecute event. You have an instance of TMediaPlayer in the MediaPlayer property of your action.

ImageIndex¶

Stores an index in a list of images. ImageIndex is a zero-based index in a list of images. TContainedAction does not provide the actual list of images, only implementations of actions in GUI application frameworks provide such a property. In general, this list of images contains images that are associated with controls and menu items that use this action. The value of ImageIndex can be propagated to all client controls and client menu items linked to the action.

Note: When ImageIndex is -1, this means that the list does not contain any images. In typical implementations of controls, an image is drawn at the leftmost position in the control, and a control’s text is drawn to the right of the image. If ImageIndex is -1, then a control does not offset the text to the right to reserve a placeholder for the image. Otherwise, if ImageIndex is not -1, then the control’s text is always drawn with the offset to the right to reserve a place for drawing an image.

Type:: int

MediaPlayer¶

Instance of TMediaPlayer that is target of the action.

Type:: MediaPlayer

SecondaryShortCuts¶

Stores shortcuts (in addition to ShortCut) for triggering the action. Actions can execute in response to multiple shortcut key combinations. SecondaryShortCuts lists all the shortcut key combinations (other than the one specified by the ShortCut property) that can trigger the action. This lets you provide additional, secondary shortcuts. When the user types one of the key combinations listed in SecondaryShortCuts, the action’s Execute method is called.

Type:: CustomShortCutList

ShortCut¶

Shortcut that triggers the action. The value of Shortcut can be propagated to all client controls and client menu items linked to the action.

Type:: int

UnsupportedArchitectures¶

Defines the set of unsupported CPU architectures. The TArchitecture type defines the arIntelX86 and arIntelX64 constants that identify the processor architectures Intel x86 and Intel x64. Use UnsupportedArchitectures to identify sets of unsupported processor architectures.

Type:: Architectures

Update()¶: Provides an opportunity to execute centralized code when an application is idle.

Visible¶

Stores whether the action representation is visible. Visible specifies the visible state for the action (True means visible, False means invisible). This Visible value is propagated to a client of the action if IsVisibleLinked method of the action link linking the client to the action returns True. If the Visible of an action is False and IsVisibleLinked of an action link returns True, then the Visible of the client (a control, menu item, or others) is also set False and this client is also invisible. Typically, IsVisibleLinked of an action link returns False if the action belongs to TCustomViewAction. Otherwise, when the action belongs to TAction, then IsVisibleLinked of an action link returns True. That is, TCustomViewAction is used when one need to provide visible representation of clients of actions that have Visible set True.

Type:: bool
