UI Automation Support for the Separator 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 Separator 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.
Separator controls are used to visually divide a space into two regions. For example, a separator control can be a bar that defines two panes in a window. If the separator can be moved, the control should be exposed as Thumb in control type.
The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Separator control type. The UI Automation requirements apply to all list controls, 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
