CBCGPDropDownToolbarButton

Detailed Description

The CBCGPDropDownToolbarButton object acts as a regular toolbar button when clicked or opens a "child" drop-down toolbar (see CBCGPDropDownToolBar) when held down for a while. If the user invokes a command by clicking on the drop-down toolbar button, the command becomes current (as well as its image) and will be executed when the user clicks the drop-down toolbar button.

A button of CBCGPDropDownToolbarButton type differs from the regular button on the toolbar by a small arrow in the right-bottom corner of the button.

The CBCGPDropDownToolbarButton object may be exported to the toolbar menu button (CBCGPToolbarMenuButton) and be shown as menu item.

You should use the CBCGDropDownToolBarButton object in conjunction with the CBCGPDropDownToolBar object as a replacement for the dummy button reserved in the parent toolbar resource (CBCGPToolBar::ReplaceButton).
