How to create popup listbox?

Question

Hi,

In my MDI application I have a button in a CDockablePane. When clicking the button I have diaply a popup listbox with image and text.

Is it possible to create popup listbox by subclassing CListBox?

Answer 1

Hello,

when you click the button you can open a CDialog without frame which is fully occupied by a listbox control. To get it to the appropiate position, you could use the button coordinates and SetWindowPos.

Without dialog can we create a popup listbox by subclassing CListbox?

IMO, CListbox is a control in a dialog, it is not a dialog. So: no, you cannot.

Look at this: https://docs.microsoft.com/cpp/mfc/hierarchy-chart

The standard way is with a Popup Menu, like CSplitButton Class

Answer 5

Controls expect to be child windows.  For example, they send notifications to their parent windows.  So a control that is not a child window will probably exhibit unusual behavior.

Answer 6

You could create a WS_POPUP CWnd and create a CListCtrl as a child of this CWnd.
