[Glade-users] Glade widget updating problem.

[koenlekkerkerker at gmail.com (Koen Lekkerkerker)]

Hi everybody, I have a problem (again) with glade. Or actually GTK2. The
problem is that my GUI (or better GUI-elements) isn't updated frequently
enough (or at least, that is my conclusion). I my case it is like this: 
I have a button. When i click it i want a scale to be set to a value 0,
a second later it needs to be 1, another second later 2, and so one
untill 10. When I make a GUI with code that fits this, it will work. But
the scale goes from 0 to 1 to 2 to 4 to 5 to 7 to 8 to 10. These double
steps dure 2 seconds (as logical). I found out that de widgets
themselves are updated directly (by using g_print(x); in my terminal)
but that their graphical appearance in the GUI isn't updated frequently
enough. Point is that I wan't the GUI to be synced with the value of the
widgets. I have this problem using glade3 and libglade2. I had the exact
same problem with glade2 using the code of it's built-in code generator.
Can anybody please help me with this? The code of my app is below. But
first another little question: is it possible to make a complete
compilation of a libglade/gtk program with the GUI built in? So that it
doesn't need the libglade library and the xml-file to run?
Thanks a lot in advance!

Here is my terminal command:
        cc -o testprogram gl3test.c `pkg-config --cflags --libs
        libglade-2.0` -export-dynamic

And here is my c file (gl3test.c):

        #ifdef HAVE_CONFIG_H
        #  include <config.h>
        #endif
        
        
        #include <gtk/gtk.h>
        #include <stdio.h>
        #include <glade/glade.h>
        
        static GtkWidget *label;
        static GtkWidget *scale;
        
        void
        on_button1_clicked                    (GtkButton       *button,
                                                gpointer
        user_data)
        {
        int x;
        char test[3];
        gtk_label_set_text(GTK_LABEL(label),"goedzo");
          for( x=0;x<=10;x++){
            gtk_range_set_value(GTK_RANGE(scale),x);
            usleep(1000000);
            sprintf(test,"%d",x);
            gtk_label_set_text(GTK_LABEL(label),test);
            g_print("%d\n",x);
            }
        gtk_range_set_value(GTK_RANGE(scale),0);
        gtk_label_set_text(GTK_LABEL(label),"klik nog een keer");
        g_print("klaar");
        }
        
        int main(int argc, char *argv[]) {
            GladeXML *xml;
        
            gtk_init(&argc, &argv);
        
            /* load the interface */
            xml = glade_xml_new("gl3test.glade", NULL, NULL);
        
            scale = glade_xml_get_widget(xml, "hscale1");
            label = glade_xml_get_widget(xml, "label1");
        
            /* connect the signals in the interface */
            glade_xml_signal_autoconnect(xml);
            /* start the event loop */
            gtk_main();
        
            return 0;
        }

and this is my xml-file (gl3test.glade):
