Hi.
I've modified your example a bit to give you a kick start with this problem.
== test.c ==
#include <gtk/gtk.h>
#include <stdio.h>
void on_combobox1_changed (GtkComboBox *widget, GtkWidget *window)
{
GtkTreeIter iter;
GtkTreeModel *model;
gchar *color;
GdkColor gcolor;
gtk_combo_box_get_active_iter( widget, &iter );
model = gtk_combo_box_get_model( widget );
gtk_tree_model_get( model, &iter, 0, &color, -1 );
gdk_color_parse( color, &gcolor );
g_free( color );
gtk_widget_modify_bg( window, GTK_STATE_NORMAL, &gcolor );
}
int
main (int argc, char *argv[])
{
GtkBuilder *builder;
GtkWidget *window;
gtk_init (&argc, &argv);
builder = gtk_builder_new ();
gtk_builder_add_from_file (builder, "test.xml", NULL);
window = GTK_WIDGET (gtk_builder_get_object (builder, "window1"));
gtk_builder_connect_signals (builder, window);
g_object_unref (G_OBJECT (builder));
gtk_widget_show (window);
gtk_main ();
return 0;
}
== end test.c ==
== test.xml ==
