GtkRange value_changed meaning...

[Carlos Savoretti <csavoretti clubsanjorge com ar>]

Hi all,

I need to catch when the vertical scrollbar from scrolledwindow

reach the max. value, it is the ending bottom. So I'm trying doing

the following:

1) Firstly set a convenient range of just one page varying from 0-1000

with:

          gtk_range_set_increments(GTK_RANGE(
                 GTK_SCROLLED_WINDOW(scrolledwindow1)->vscrollbar),
                 1.0,
                 1000.0);
         gtk_range_set_range(GTK_RANGE(
                 GTK_SCROLLED_WINDOW(scrolledwindow1)->vscrollbar),
                 0.0,
                 1000.0);

2) Then handle the "value-changed" :

         g_signal_connect((gpointer)
                 GTK_RANGE(
                 GTK_SCROLLED_WINDOW(scrolledwindow1)->vscrollbar),
                 "value_changed",
                 G_CALLBACK(on_scrolledwindow_vscrollbar_value_changed),
                 (gpointer)ddc_data);

Inside the callback I use:

       gdouble value = gtk_range_get_value(range);

But this `value' seems arbitrary to me because have no relation with the

disired limits set above.

Any clue ?

A lot of thanks.
