Popping up a listbox from a listbox item?


I want to create a CListBox-derived class, called CPoppableListBox.

When the user selects an item, a new listbox would pop up offering him a choice of strings.

When he selects one, it would replace the original item, and the popped-up choices listbox would be destroyed. Or he could cancel the operation by clicking a second time on the underlying item.

The pop up listbox can be any size, so shouldn't be clipped to anything smaller than the desktop.

Are there any such classes in existence, and if not how do I create one?

You should probably create CWnd derived class wich will be popup and contain CListBox in it

Thanks cyrilbdt, but how do I handle the selection messages properly?

With a CListBox within my pop up window as you suggest, the pop up window is the parent and therefore handles LBN_SELCHANGE messages sent from its listbox.

I need to respond to LBN_SELCHANGE by changing the *underlying* listbox item (the one that was originally clicked). Is there some way I can route the message so that it bypasses the pop up window and gets handled by the "grandparent" listbox?
