Observação

Esta documentação destina.Os desenvolvedores do NET Framework que desejam usar o gerenciado UI Automation classes definidas na System.Windows.Automation namespace.As informações mais recentes sobre UI Automation, consulte API de automação do Windows: Automação da interface do usuário.

Este tópico fornece informações sobre UI Automation suporte para o cabeçalho o tipo de controle. In UI Automation, a control type is a set of conditions that a control must meet in order to use the ControlTypeProperty property. As condições incluem as diretrizes específicas para UI Automation estrutura de árvore, UI Automation os valores de propriedade e padrões de controle.

The header control provides a visual container for the labels for rows or columns of information.

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

Este tópico contém as seguintes seções.

  • Required UI Automation Tree Structure
  • Required UI Automation Properties
  • Required UI Automation Control Patterns
  • Required UI Automation Events

Required UI Automation Tree Structure

The following table depicts the control view and the content view of the UI Automation tree that pertains to header controls and describes what can be contained in each view. For more information about the UI Automation tree, see Visão geral da árvore de automação de interface do usuário.

Control View

Content View

Header

  • HeaderItem (1 or more)

None

Header controls always have 1 or more children in the control view of the UI Automation tree.

Header controls have zero children in the content view of the UI Automation tree.

Required UI Automation Properties

The following table lists the UI Automation properties whose value or definition is especially relevant to header 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 outermost rectangle that contains the whole control.

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.

IsControlElementProperty

True

The header control is always included in the control view of the UI Automation tree.

The following table lists the UI Automation control patterns required to be supported by all header controls. For more information on control patterns, see Visão Geral de Padrões de Controle de Automação de Interface de Usuário.
