http://forums.fedoraforum.org – Dear friends, It seems that when I am using adawita theme in f17, I cannot use "gtk_widget_modify_bg" etc to change the color of a widget. When using other themes though, (like say Low contrast), its absolutely ok. I am posting a complete code below, I will be grateful if somone shows me how to override this behavior. Code: #include <gtk/gtk.h> int main(int argc, char *argv[]) { GtkWidget *window; GtkWidget *grid; GtkWidget *menubar; GtkWidget *filemenu; GtkWid (HowTos)
