UI Automation Support for the Title Bar Control Type

This topic provides information about UI Automation support for the Title 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.

Title bar controls represent titles or caption bars in a window.

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