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.
