TdxNavBarCustomSignPainter Class

Serves as the base for painter classes used to draw a group header sign.

Declaration

TdxNavBarCustomSignPainter = class(
    TObject
)

Remarks

This class provides the DrawSign method, which calls the virtual InternalDrawSign method. TdxNavBarCustomSignPainter descendants override the InternalDrawSign method to custom paint the group header sign (double arrow).

TdxNavBarCustomSignPainter descendants include:

Descendant	Comment	Example
TdxNavBarExplorerBarSignPainter	Used in the ExplorerBarView and UltraFlatExplorerBarView
TdxNavBarAdvExplorerBarSignPainter	Used in the AdvExplorerBarView
TdxNavBarXPExplorerBarSignPainter	Used in the XPExplorerBarView
TdxNavBarOffice11ExplorerBarSignPainter	Used in Office11ExplorerBarView
TdxNavBarOffice11SignPainter	Used in Office11TaskPaneView

When you create a custom View for a NavBar control, you can provide your own painter for group header signs. In this case, use TdxNavBarCustomSignPainter or its descendant as the base class for your painter and override the InternalDrawSign method to draw the group header sign as your needs dictate. Refer to the Registering Custom Views topic for details.
