Can gtk resource file change the attributes of a group of widget inone call?

[Wang Li <blazing public cs hn cn>]

I want to know whether the rc of gtk can change the

attributes of a group of widgets. So I build the

following resource file: test.rc

 

style "pink_button"  {
 bg[NORMAL]={1.0,0.7,0.7}
}
style "blue_button"  {
 bg[NORMAL]={0.7,0.7,1.0}
}
style "green_button"  {
 bg[NORMAL]={0.7,1.0,0.7}
}

 

widget "pinkmain.*GtkButton*" style "pink_button"
widget "bluemain.*GtkButton*" style "blue_button"
widget "greenmain.*GtkButton*" style "green_button"

And then, the corresponding c program testrc.c:

 

#include <gtk/gtk.h>

 

GtkWidget *pink_button,*blue_button,*green_button;

 

void set_to_pink(GtkObject *pgo)  {
 gtk_widget_set_name(GTK_WIDGET(pgo),"pinkmain");
}
void set_to_blue(GtkObject *pgo)  {
 gtk_widget_set_name(GTK_WIDGET(pgo),"bluemain");
}
void set_to_green(GtkObject *pgo)  {
 gtk_widget_set_name(GTK_WIDGET(pgo),"greenmain");
}

 

int main( int   argc,
          char *argv[] )
{
  /* GtkWidget is the storage type for widgets */
  GtkWidget *window;
  GtkWidget *box;

 

  /* Initialize the toolkit */
  gtk_init (&argc, &argv);

 

  gtk_rc_parse("test.rc");
 
  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

 

  gtk_window_set_title (GTK_WINDOW (window), "RC Buttons");

 

  gtk_signal_connect (GTK_OBJECT (window), "destroy",
                      GTK_SIGNAL_FUNC (gtk_main_quit), NULL);

 

  gtk_container_set_border_width (GTK_CONTAINER (window), 10);

 

  box = gtk_hbox_new (FALSE, 0);
  gtk_container_set_border_width (GTK_CONTAINER (box), 2);
  gtk_container_add (GTK_CONTAINER (window), box);

 

  gtk_widget_show(box);

 

  pink_button = gtk_button_new_with_label("Pink");
  gtk_signal_connect_object(GTK_OBJECT(pink_button),"clicked",
    GTK_SIGNAL_FUNC(set_to_pink),GTK_OBJECT(window));
  gtk_box_pack_start (GTK_BOX (box), pink_button, FALSE, FALSE, 3);
  gtk_widget_show(pink_button);

 

  blue_button = gtk_button_new_with_label("Blue");
  gtk_signal_connect_object(GTK_OBJECT(blue_button),"clicked",
    GTK_SIGNAL_FUNC(set_to_blue),GTK_OBJECT(window));
  gtk_box_pack_start(GTK_BOX (box), blue_button, FALSE, FALSE, 3);
  gtk_widget_show(blue_button);

 

  green_button = gtk_button_new_with_label("Green");
  gtk_signal_connect_object(GTK_OBJECT(green_button),"clicked",
    GTK_SIGNAL_FUNC(set_to_green),GTK_OBJECT(window));
  gtk_box_pack_start(GTK_BOX (box), green_button, FALSE, FALSE, 3);
  gtk_widget_show(green_button);
 
  gtk_widget_show (window);
 
  gtk_main ();
 
  return(0);
}

After I compile it by 'gcc -Wall -o testrc testrc.c `gtk-config

--cflags --libs`'. The color of the three button don't change

there background color with my click.

 

What the mechanism of the gtk resource file? Is it can change

a group of widgets in one call?

 

Thank You My Friends.
