Listbox with Checkbox

[BOB MECHLER]

Dean,

Thanks for the a nice subclassing of a listbox example with checkbox in the source code area. Very clear presentation.

I think you are referring to this....

Not that this isn't a nice example of owner-drawing, but wouldn't a ListVIEW control with Style LVS_EX_CHECKBOXES be an easier way to accomplish the same thing?

No subclassing, no owner-draw. Of course, owner-drawing may have been the purpose of the demo.

The benefit for me was in the subclassing and ownerdrawing that was cleanly demonstrated. I've been pretty weak in both areas.

Bob, thanks, but I just reworked the layout and added the toggle check and get check. Someone far more capable created the basic functionality.

WM_DRAWITEM is handled wrong, read: not handled.
A common mistake

This is for a listVIEW control, but it includes time-tested drawing of checkboxes...
