Re: [gtk-list] opening modal windows from the "button-press-event" handler forclist

I will modify the error_message() like this:

void error_message(const char* title,const char* text)
{
    GtkWidget *dialog;
    GtkWidget *button,*hb,*l;
    char* str;

    dialog = gtk_dialog_new();
    gtk_window_set_title (GTK_WINDOW (dialog), title);    

    l = gtk_label_new(text);

    hb = gtk_hbox_new(1,0);
    gtk_box_pack_start (GTK_BOX (hb), l, TRUE, TRUE, 43);    
    gtk_box_pack_start (GTK_BOX (GTK_DIALOG (dialog)->vbox),
		hb, TRUE, TRUE, 0);			    
    button = gtk_button_new_with_label("OK");
// ???
    gtk_signal_connect_object(GTK_OBJECT(button),"clicked",
	GTK_SIGNAL_FUNC(gtk_main_quit),GTK_OBJECT(dialog));

/**********************************************************************
 This signal connect is wrong, it should be like this:
 gtk_signal_connect_object(GTK_OBJECT(button), "clicked",
	GTK_SIGNAL_FUNC(gtk_widget_destroy), GTK_OBJECT(dialog));
***********************************************************************/

    gtk_box_pack_start (GTK_BOX (GTK_DIALOG (dialog)->action_area),
                            button, TRUE, TRUE, 0);
    gtk_window_set_modal (GTK_WINDOW(dialog),TRUE);
    GTK_WIDGET_SET_FLAGS (button, GTK_CAN_DEFAULT);
    gtk_widget_grab_default (button);
	        
    gtk_widget_show_all(dialog);
// ???
    gtk_main();    
    gtk_window_set_modal (GTK_WINDOW(dialog),0);
    gtk_widget_destroy(dialog);

/*************************************************************************
  There is no need to do these, just delete them. because
when you click button OK, the signal "clicked" connected to
it will destroy the dialog.
*************************************************************************/
};
