UI Automation Support for the ToolBar Control Type

System_CAPS_ICON_note.jpg 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 ToolBar 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. Tool bar controls enable end users to activate commands and tools contained within a application.

The following sections define the required UI Automation tree structure, properties, control patterns, and events for the ToolBar control type. The UI Automation requirements apply to all tool bar controls, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.

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

Control ViewContent View

- Various controls (0 or more)

- Various controls (0 or more)

A tool bar control can contain any type of control within its subtree. They most often contain buttons, combo boxes, and split buttons.

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

UI Automation PropertyValueNotes
AutomationIdPropertySee notes.The value of this property needs to be unique across all controls in an application.
BoundingRectanglePropertySee notes.The outermost rectangle that contains the whole control.
ClickablePointPropertySee notes.Supported if there is a bounding rectangle. If not every point within the bounding rectangle is clickable, and you perform specialized hit testing, then override and provide a clickable point.
IsKeyboardFocusablePropertySee notes.If the control can receive keyboard focus, it must support this property.
NamePropertyDependsThe tool bar control does not need a name unless more than one is used within an application. If more than one is present, each must have a distinguishing name (for example, Formatting or Outlining).
LabeledByPropertyNullTool bar controls never have a label.
ControlTypePropertyToolBarThis value is the same for all UI frameworks.
LocalizedControlTypeProperty"tool bar"Localized string corresponding to the ToolBar control type.
IsContentElementPropertyTrueThe tool bar control is always content.
IsControlElementPropertyTrueThe tool bar control must always be a control.

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

Control PatternSupportNotes
ExpandCollapsePatternDependsIf the tool bar can be expanded and collapsed to show more items, then it must support this pattern.
DockPatternDependsIf the tool bar can be docked to different parts of the screen, then it must support this pattern.
TransformPatternDependsIf the tool bar can be resized, rotated, or moved, it must support this pattern.

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

UI Automation EventSupportNotes

IsOffscreenProperty property-changed event.RequiredNone
IsEnabledProperty property-changed event.RequiredNone
ExpandCollapseStateProperty property-changed event.DependsNone
