I want (need) to be able to create radio buttons that are owner-drawn (like a CBitmapButton) but still act like radio buttons.
I tried setting BS_OWNERDRAW in my .RC file and writing a class similar to CBitmapButton but with a DrawItem that tests GetCheck() value and draws the appropriate bitmap (down for checked, up for unchecked, etc.)
But this did not work - BS_OWNERDRAW is 0x0b and BS_AUTORADIOBUTTON is 0x09 (1011 and 1001). If you OR them, you get 0x0b - BS_OWNERDRAW. Consequently, the button acts as if it were a normal CBitmapButton and the GetCheck() member always returns 0, even if I do a SetCheck(1) immediately before.
So, is there any reasonable way to do this?
