Background on custom common controls?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Does anybody have a good idea of how to get the blue gradient as the
background for common controls? See the CommonControls sample for what
I mean, but that sample only uses the office 2000 theme, probably for
this reason.

I can override CMainFrame::OnCtlColor and return a new solid brush for
the background color, which would let it work with the Office XP theme
and blend in correctly, but I don't see any good way to put a gradient
underneith the common controls.

I have also tried deriving a class from CSliderCtrl and overriding
OnPaint to use CXTMemDC, but the gradient from the toolbar still does
not show through ever, I just end up with the hall-of-mirrors type
effect.

	I have done this type of thing with CDialogBar, where I want the background of the CDialogBar to reflect the current theme colors. The CSliderCtrl is a bit more difficult since it is drawn in stages (see http://www.codeproject.com/miscctrl/transparentslider.asp?pr int=true). You would also have to call something like: XTPPaintManager()->GradientFill(pDC,rc,XTPPaintMana ger()->GetXtremeColor(XPCOLOR_BASE),XTPPaintManager()-> ;GetXtremeColor(55),FALSE); in order to get the proper gradient fill. I suspect this would be a bit tricky since you are only filling a portion of the CommandBar (the slider itself).
