TcxTabControl Class

A tab control.

Declaration

TcxTabControl = class(
    TcxCustomTabControl
)

Remarks

Tab controls are designed to arrange UI elements into multiple pages. Users can click tabs to switch between corresponding pages. The TcxTabControl displays tab-dependent content using the same page layout. If you need to display different UI elements on different pages, use the TcxPageControl component instead.

Getting Started

Read Tutorial: Tab Control Tutorial: This tutorial creates a simple tabbed user interface using the TcxTabControl component.

UI Automation/Accessibility Support

The TcxTabControl control is mapped to a node in the UI Automation tree when the global UI Automation flag (dxUIAutomationEnabled) is enabled.

UI Automation Settings

Use Properties.Automation.Name and Properties.Automation.Description properties to specify the tab control name and to add optional information that are then used to clarify UI element purpose for users who rely on third-party assistive tools (such as Microsoft Narrator).

Refer to the TdxAutomationElementSettings class description for detailed information on all available options.
