UI Automation Support for the Status Bar Control Type

This topic provides information about UI Automation support for the Status Bar 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.

A status bar control displays information about an object being viewed in a window of an application, the object's component, or contextual information that relates to that object's operation within your application.

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

This topic contains the following sections.

Required UI Automation Tree Structure

The following table depicts the control view and the content view of the UI Automation tree that pertains to status 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 View Content View
  • StatusBar

    • Edit (1 or more)

    • Progress Bar (0 or many)

    • Image (0 or many)

  • StatusBar

  • Edit (1 or more)

  • ProgressBar (0 or many)

  • Image (0 or many)

Required UI Automation Properties

The following table lists the UI Automation properties whose value or definition is especially relevant to progress bar 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 bounding rectangle of a status bar must encompass all of the controls contained within it.

ClickablePointProperty

See 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.

IsKeyboardFocusableProperty

See notes.

If the control can receive keyboard focus, it must support this property.

NameProperty

See notes.

The status bar control does not need a name unless more than one is used within an application. In this case, distinguish each bar with names such as "Internet Status" or "Application Status."

LabeledByProperty

Null

The status bar control usually does not have a label.

ControlTypeProperty

StatusBar

This value is the same for all UI frameworks.

LocalizedControlTypeProperty

"status bar"

Localized string corresponding to the Status Bar control type.

IsContentElementProperty

True

The status bar control always contains content.

IsControlElementProperty

True

The status bar control is always a control.

IsOffscreenProperty

Depends

A status bar control will return True for this property if it is not currently visible on the screen.

OrientationProperty

Depends

The value of the control's orientation: horizontal or vertical.

IsKeyboardFocusableProperty

False

HelpTextProperty

""

Status bars do not have Help text.

AcceleratorKeyProperty

Null

Status bars do not have accelerator keys.

AccessKeyProperty

""

Status bars do not receive keyboard focus. Assistive technologies are able to programmatically read the contents.

Required UI Automation Control Patterns

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

Control Pattern/Pattern Property Support/Value Notes

IGridProvider

Optional

Status bar controls should support the Grid control pattern so that individual pieces can be monitored and easily referenced for information.

Required UI Automation Events

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