In Automatización de la interfaz de usuario, 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 Automatización de la interfaz de usuario tree structure, Automatización de la interfaz de usuario property values and control patterns.
Menu bar controls are an example of controls that implement the MenuBar control type. Menu bars provide a means for users to activate commands and options contained in an application.
The following sections define the required Automatización de la interfaz de usuario tree structure, properties, control patterns, and events for the MenuBar control type. The Automatización de la interfaz de usuario requirements apply to all list controls, whether Windows Presentation Foundation (WPF), Win32, or formularios Windows Forms.
