CBCGPColorBar

Detailed Description

The CBCGPColorBar class provides the functionality of the regular docking control bar specially designed to handle various color selection issues in the document/application. The list of built-in features (no additional programming required) includes:

• automatically adjusted list of document colors
• ability to save and restore its state in conjunction with the document state
• "automatic" button
• custom color selection by using CBCGPColorPickerCtrl control
• "tear-off" state (when created from CBCGPColorMenuButton)

Usually, you don't need to create the CBCGPColorBar object directly. It's creation should be handled by CBCGPColorMenuButton (used from menu / toolbar) or by CBCGPColorButton otherwise. You have to perform the following steps to incorporate the CBCGPColorBar functionality into your application:

• Create a regular menu button and assign it some ID, for example ID_CHAR_COLOR.
• In your frame window class override CBCGPFrameWnd::OnShowPopupMenu method and replace the regular menu button by CBCGPColorMenuButton object (call CBCGPToolBar::ReplaceButton).

It's advised to set all the desired styles and enable/disable required features of the CBCGPColorBar during CBCGPColorMenuButton creation, because it will create dynamically the CBCGPColorBar object when the BCGP Framework calls CreatePopupMenu().

CBCGPColorBar object notifies its parents about user selection by sending ON_COMMAND message, where the command ID is the identifier that was assigned to the replaced menu button (ID_CHAR_COLOR in the example above).
