CBCGPToolbarMenuButton

Detailed Description

The CBCGPToolbarMenuButton class extends the functionality of the regular CBCGPToolbarButton.

A CBCGPToolbarMenuButton object can represent the following button types:

• a regular menu item
• a menu item with a sub-menu
• a tool bar button with a submenu; in this case the button has a small arrow near the text or image. When the user clicks the button the submenu is displayed
• a tool bar button, which executes a default command or displays a popup menu; in this case the button has a small arrow separated from the text or image. When the user presses the arrow, the submenu is displayed; otherwise the default button's command is executed.

The type of the button is detected automatically, according to the constructor's parameters.
