UI Automation Support for the Window Control Type

Note

This documentation is intended for .NET Framework developers who want to use the managed UI Automation classes defined in the System.Windows.Automation namespace. For the latest information about UI Automation, see Windows Automation API: UI Automation.

This topic provides information about UI Automation support for the Window control type. In UI Automation, a control type is a set of conditions that a control must meet in order to use the ControlTypeProperty property. The conditions include specific guidelines for UI Automation tree structure, UI Automation property values, and control patterns.

The window control consists of the window frame, which contains child objects such as title bar, client, and other objects.

The UI Automation requirements in the following sections apply to all controls that implement the Window control type, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.

This topic contains the following sections.

• Required UI Automation Tree Structure
• Required UI Automation Properties
• Required UI Automation Control Patterns
• Required UI Automation Events
• Related Topics

Required UI Automation Tree Structure

The following table depicts the control view and the content view of the UI Automation tree that pertains to window controls and describes what can be contained in each view. For more information on the UI Automation tree, see UI Automation Tree Overview.

Control View	Content View
Window	Window

Required UI Automation Properties

The following table lists the UI Automation properties whose value or definition is especially relevant to window controls. For more information about UI Automation properties, see UI Automation Properties for Clients.

UI Automation Property	Value	Notes
AutomationIdProperty	See notes.	The value of this property needs to be unique across all controls in an application.
BoundingRectangleProperty	See notes.	The outermost rectangle that contains the whole control.
ClickablePointProperty	See notes.	The window control must have a clickable point that will result in causing the window to become selected or unselected.
ControlTypeProperty	Window	This value is the same for all UI frameworks.
IsContentElementProperty	True	The window control must always be content.
IsControlElementProperty	True	The window control must always be a control.
IsKeyboardFocusableProperty	See notes.	If the control can receive keyboard focus, it must support this property.
LabeledByProperty	null	Window controls do not have a static Window label.
LocalizedControlTypeProperty	"window"	Localized string corresponding to the Window control type.
NameProperty	See notes.	The window control always contains a primary Window element that relates to what the user would associate as the most semantic identifier for the item.

Required UI Automation Control Patterns

The following table lists the UI Automation control patterns required to be supported by window controls. For more information on control patterns, see UI Automation Control Patterns Overview.

Control Pattern	Support	Notes
IDockProvider	Conditional	Must be supported if the window has the ability to be docked.
ITransformProvider	Required	Enables the window to be moved, resized, or rotated on the screen.
IWindowProvider	Required	Enables specific operations for the window.

The following table lists the UI Automation events required to be supported by all window controls. For more information about events, see UI Automation Events Overview.

AutomationFocusChangedEvent	Required	None
BoundingRectangleProperty property-changed event.	Required	None
IsEnabledProperty property-changed event.	Required	None
