Hi All ,

For GTK+ 3.8 onwards to set opacity gtk_widget_set_opacity is used ( gtk_window_set_opacity has been deprecated ).
I made a sample in which a button is created under toplevel window . The above opacity works for buttons ( child widgets ) not for toplevel window .
If I set the opacity in toplevel window , then it has no effect .
Could anyone tell how to set the opacity to level window .

code snippet :

int main( int argc,
char *argv[] )
{
GtkWidget *window;
GtkWidget *button;
GdkRGBA color ;

gtk_init (&argc, &argv);

GtkBuilder *builder = gtk_builder_new ();

gtk_builder_add_from_file (builder, "opacity.glade", NULL);


window = GTK_WIDGET (gtk_builder_get_object (builder, "window1"));
button = GTK_WIDGET (gtk_builder_get_object (builder, "button1"));

gdk_rgba_parse (&color, "blue");
gtk_widget_override_background_color (window , 0, &color);
gtk_widget_set_opacity ( window , 0.5 );

gtk_widget_show_all (window);

gtk_main ();

return 0;
}
