You may know the Nim editor from https://github.com/ngtk3/NEd Getting tooltips with white background for a dark gtksourceview color scheme was already one of the harder task for GTK 3.18 -- but somehow I managed it. Recently I got GTK 3.20 and had to notice that setting background for tooltip does not work any more. Setting the colors was done this way for GTK 3.18: const str0 = ".tooltip {background-color: rgba($1, $2, $3, 0.9); color: rgba($4, $5, $6, 1.0); \n}" proc setTTColor(fg, bg: cstring) = var rgba_bg: gdk3.RGBAObj var rgba_fg: gdk3.RGBAObj if not rgbaParse(rgba_fg, bg): return if not rgbaParse(rgba_bg, fg): return let str: string = str0 % map([rgba_bg.red, rgba_bg.green, rgba_bg.blue, rgba_fg.red, rgba_fg.green, rgba_fg.blue], proc(x: cdouble): string = $system.int(x*255)) var gerror: GError let provider: CssProvider = newCssProvider() let display: Display = displayGetDefault() let screen: gdk3.Screen = getDefaultScreen(display) styleContextAddProviderForScreen(screen, styleProvider(provider), STYLE_PROVIDER_PRIORITY_APPLICATION.cuint) discard loadFromData(provider, str, GSize(-1), gerror) objectUnref(provider) Even for a simple test application setting of background color seems not to work any more: https://github.com/ngtk3/nim-gtk3/blob/master/test/colors.nim I have the feeling that fixing this basically simple problem will take much time again. Have already done some (Google) investigations yesterday, but found no good hints. GtkInstector seems to be not really helpful for tooltips unfortunately. I think I can remember some questions about CSS problems on this list in recent months, some maybe with replies of Mr Bassi. Have to dig :-) _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
