Implement themes
UtilGtk.ErasePaint()
//trying gray background for all the images Gdk.GC pen_gray; pen_gray = new Gdk.GC(da.GdkWindow); pen_gray.Foreground = UtilGtk.GRAY; px.DrawRectangle (pen_gray, true, 0, 0, da.Allocation.Width, da.Allocation.Height); da.QueueDraw(); // -- refresh
and with ImageMagick change color icons and have colors in graph like: Main color/Secondary color... depending on themes
