To create and use a new context-sensitive menu: * Derive a new subclass from ContextMenu, e.g. ViewContextMenu. * Create the operations that you want to use from the menu or use existing operations. * Implement a new Build function in your subclass to build your menu using the helper functions provided (see func headers for more details). * That's all there is to it - the menu system handles everything else! Note: There are guidelines about how to construct a pop-up menu and when to open it. * The menu should be formed something like this: Clicked object's primary commands Clicked object's transfer commands (e.g. cut, copy, etc...) "Properties..." command * The menu should be opened in response to a BUTTON UP event!!! ********************************************************************************************/ class ContextMenu : public CC_CLASS_MEMDUMP { // Give my name in memory dumps CC_DECLARE_MEMDUMP(ContextMenu); public: ContextMenu(); virtual ~ContextMenu(); // Major functions...
