Este tópico fornece informações sobre UI Automation suporte para o grupo 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. The conditions include specific guidelines for UI Automation tree structure, UI Automation property values, and UI Automation control patterns.
The group control represents a node within a hierarchy. O tipo de controle de grupo cria uma separação na UI Automation para que os itens são agrupados tenham uma divisão lógica dentro da árvore de UI Automation árvore.
The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Group control type. The UI Automation requirements apply to all group controls, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.
Este tópico contém as seguintes seções.

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

Typically group controls will have the Suporte de Automação de Interface de Usuário para o Tipo de Controle Item de Lista, Suporte de Automação de Interface de Usuário para o Tipo de Controle TreeItem, or UI Automation Support for the DataItem Control Type control types found underneath them in the subtree. Because 'Group' is a generic container, it is possible for any type of control to be under the Group control in the tree.
Required UI Automation Properties
The following table lists the UI Automation properties whose value or definition is especially relevant to group controls. For more information about UI Automation properties, see UI Automation Properties for Clients.
