[Java-gnome-developer] auto-scroll in ScrolledWindow

[Manuel C. <ll...@us...>]

Hi all,

Here is how I got auto-scroll working. By auto-scroll, I mean the
(vertical) scrollbar automatically move when a hidden widget gets focus,
so you can *automatically* view that widget instead of manually doing
the scroll.

How it should work:

vbox.setFocusVAdjustment(scrolledWindow.getVAdjustment());

setFocusVAdjustment() is missing in java-gnome (Container class).


This is clumsy, but it works _now_:

// since the method is protected, extend the class to reveal it
public class Container2 extends Container {

    // constructor ignored

    public static void gtk_container_set_focus_vadjustment2(Handle a,
Handle b) {
        gtk_container_set_focus_vadjustment(a, b);
    }
}


// code in the program
Container2.gtk_container_set_focus_vadjustment2(vbox1.getHandle(),
scrolledWindow.getVAdjustment().getHandle());


... and it works! really ;)

Hope it helps!

great! :)

Type a tutorial or document't in the web page. I think is the better way to share knowledge.

The method _is_ listed in the Gtk api (
http://developer.gnome.org/doc/API/2.0/gtk/GtkContainer.html), so this extr=
a
voodoo business won't be needed once we expose it with public methods.
