I have a CListCtrl-derived class which instantiates a context menu. The ListCtrl object is located within a form view. How do I allow the view class to process the menu selection rather than the CListCtrl-derived class? ON_COMMAND(ID_PROP_TEST, OnPropTest) handled by view class.

Hi sgraves66,

do you use CMenu::TrackPopupMenu in the derived list class's OnContextMenu to
display the menu? If so simply pass a pointer to the view instead of the pointer
to the list as 4th parameter...

hope that helps,

The handle arg sunk in right after I posted this -- Didn't think about it the first go round :)

My next task is to disable menu items based upon the mouse cursor in relation to the items (all in report view). I've added remove / remove selected / remove all to the popup menu. I just need to disable "remove" if no items are present below the mouse cursor (in whitespace). How can I reference the popup menu from the view class in order to make these changes?

Hi again,

you can add a ON_COMMAND_UPDATE_UI handler for that menu item in your view
class and in there for the best call a function you implement in the list class which
returns TRUE if a item is beyond the mousecursor (how to do this depends a little
on other things you do in OnContextMenu(), i.e. if the selection changes if you click
with right mouse button on an item or not) and FALSE otherwise. With this returned
value you can call 'pCmdUI->Enable( <theReturnedValue> )' to en-/disable the item.

Hello,

You can repost a message (the same perhaps) to the View class, and also add a message handler there...
