Is there an alternative ? Thanx again Hia, Interesting question I thought to myself when I read your post. Surely it can't be very hard - well, that's what I thought at the time, anyway... Upon further thought and searching, I couldn't remember seeing a program around that does do it, then I found DzA Patcher sitting around here. After a bit more searching, I found a couple of articles of note on Microsoft's site. The first one mentions that after getting the transparent background to work, it screwed up when he added an XP-themes manifest file. Here ----> [b]http://forums.msdn.microsoft.com/en-US/vcgeneral/thread/a0db67c8-3b51-4451-a636-a2737e6b3e27 About then, I noticed that DzA Patcher didn't use XP themes. A few moments later I came across a gold nugget as M$s site. In it, it was said that you cannot change the colour of check-box text when using a manifest file, because of the way that comctl32.dll works However, they do propose some work-arounds. You can either custom-draw the whole control OR just cheat, and have no text on the check-box control and just put a static in place to serve as the label. It still seems like a bit of a PITA, but sounds fairly light-weight and still quite manageable. Here ----> [b]http://support.microsoft.com/kb/944311 Just get ready for a work-out if you want to put the 'currently selected control' box around the text, or indeed check/uncheck the box when the label is clicked. (Perhaps you could use a check-box label that just consisted of spaces to get around these two issues - though this leaves you with the problem of how to stop the 'currently selected control' box from covering-up your static) Using the spaces-for-a-label idea would leave you in a world of pain as you would then have to replace the WindowFunction of the check-box, to make sure that it didn't cover-up your static label. To be honest, I'd be inclined to just make it work without XP themes.. Link to comment
alaphate Posted July 24, 2008 Share Posted July 24, 2008 You should deploy WM_CTLCOLORSTATIC message:LOGBRUSH logTrans;logTrans.lbStyle = BS_HOLLOW; //transparent brushcase WM_CTLCOLORSTATIC: SetTextColor((HDC)wParam, RGB(255,0,0)); SetBkMode((HDC)wParam,TRANSPARENT); return (int)CreateBrushIndirect(&logTrans);//You have to return a brush, or SetTextColor wouldn't work Link to comment
alaphate Posted July 24, 2008 Share Posted July 24, 2008 BTW, how to change the square box's background color? Link to comment
Ufo-Pu55y Posted July 24, 2008 Share Posted July 24, 2008 Afaik nowai without subclassing that control. Simply subclass it and draw it on your own. Here's an example: Custom_Chkbox.rar PS: My source is too lousy to post Link to comment
enhzflep Posted September 19, 2008 Share Posted September 19, 2008 Yup, good-old subclassing appears to be the order of the day. I got bored and had a quick play with it again overnight. It's nothing special - the code is pretty nasty and there are some issues with flicker since I couldn't be bothered double buffering at all. It still needs to have far more messages handled - you can't even give it the keybord focus or check/uncheck it using the keyboard. I had fun anyway. Oh and btw alaphate, you can change the background colour of the box itself on line 236 of this code. Anyhow, if anyone wants it, it's here. customCheckBox.zip Link to comment
