Bug ID: 44633
           Summary: Checboxes and Radiobuttons blank out the text area
                    that follows them
           Product: Wine
           Version: 3.2
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdi32

Because it's not possible to control the text color for themed checkboxes and
radiobuttons, I have implemented a kludge in my app that works on Windows, but
not WINE.  I create checkboxes and radiobuttons as two widgets: the button,
with a null text string (but sized as if it contained the text so that clicking
on the text still activates the button), followed by a static text item for the
label, which I draw in black or white depending on the background color.

I process the WM_CTLCOLOR... messages, and set the background mode to
TRANSPARENT, but I return a non-null background brush.  If I don't do that, the
button's focus rectangle doesn't go away when it loses focus.  But since the
text is null, Windows doesn't draw anything where the text would go.  My static
text control draws in the same place - resulting in what looks like a normal
check/radiobutton, but with the text in the color I want.

This works fine on Windows, and I think it used to work under WINE (but don't
quote me - this is a recent feature, and I may have never tested it under a
prior version of WINE).  In version 3.2 at least, the radiobutton or checkbox
seems to be overwriting my static text control - so that I don't see the text
at all.  I.e., WINE is drawing the full text rectangle, even though it contains
a null string.  Either Windows only draws the rectangle for the actual 0-sized
text string, or it's order of operations allows my static text to remain
visible.  But in Windows, there's no 'flashing' of the text, so I suspect the
background rectangle is being sized to the null string and the static label is
never erased and redrawn.

In WINE, when I click the radiobutton, I can see my static text label flash on
- but it is immediately overwritten by a blank text rectangle drawn by WINE.
Yes, my code is a bit of a kludge, but it works on Windows (and I know of no
other way to control the color of check/radiobutton text).  It'd be nice if it
worked on WINE too, no?
