Hi All,
I realized the way I asked my question previously was not very clear. I have window which has a background image, on top which are widgets and some small bitmaps, working exactly as required. Three of the bitmaps I would like to appear 100% transparent normally, invisible, so the user does not see them, but when a flag is set they are opaque. Is this just the matter of setting the GUI_SetAlpha() to the appropriate value before drawing the bitmap, then re-setting after so nothing else is changed? triggered with WM_PAINT.
Kind Regards
MikeZ
