Listbox and mouse

[Peter Lameijn]

It seems a listbox with %LBS_NOTIFY doesn't generate right mouse button events or %WM_KEYDOWN.
Is there a way to receive them? (Want to use right mouse and INS/DEL keys...)

those are low-level messages which the control does not reflect/pass back to the parent callback, so you'll need to subclass the control in order to intercpt such messages.

some time back, i posted an example (in the source code forum) which shows how to subclass an edit control - this exact code should work fine for subclassing a listbox.

see

i hope this helps!

peter,

i had a similar problem a few weeks ago. windows uses right mouse button as a getting help command - you'll get a wm_contextmenu message when you right-click on the listbox. look at http://www.powerbasic.com/support/pb...ead.php?t=3514 - fred oxenby posted a very useful sample code.

Lance, Aldo,
Thanks! It seems both methods can solve my problem. Wouldn't it be a lot easier if
controls had a bit more equal behaviour (Listview DOES return a right-click; why listbox not?)
BTW: The dropdown part of a combobox doesn't seem to generate any event.
Is this already subclassed to the edit box part?
