DisplayButtons, VIRTUAL

The DisplayButtons method enables and disables the appropriate toolbar buttons for the ToolbarListboxClass object based on the values of the HelpButton, InsertButton, ChangeButton, DeleteButton, and SelectButton properties.

Implementation:

The TakeToolbar method calls the DisplayButtons method. The DisplayButtons method calls the PARENT.DisplayButtons method (ToolbarTarget.DisplayButtons) to handle buttons common to all ToolbarTargets.

Example:

CODE

Toolbar.Init                      !initialize Toolbar object

 BRW1.AddToolbarTarget( Toolbar ) !register a BrowseBox target

 ToolBar.SetTarget( ?Browse:1)    !calls DisplayButtons via TakeToolbar

 

MyToolbarListboxClass.DisplayButtons PROCEDURE !a derived class virtual

CODE

DISABLE(Toolbar:History)         !disable toolbar ditto button

ENABLE(Toolbar:Locate)           !enable locator button

PARENT.DisplayButtons            !call base class DisplayButtons
