Re: [gtk-list] Re: Scrolling multiple widgets at once

["Donna S. Martin" <donna omartin com>]

Adjustments are a GTK+ object used to control the
range widgets (scrollbars, scales, etc).  To have the movement
of one widget cause the movement of another, you share
the GtkAdjustment value.  When you create a scrollbar, scale,
scrolled window, text widget, etc., you specify an adjustment.
 Normally it is just NULL which allows the widget to
create its own adjustment. The main thing is to have the
widgets you want tied to each other share the same
GtkAdjustment.  You still have 2 scrollbars, but one GtkAdjustment.

There is an example of adjustments in the tutorial. Once you look
through that, I think you'll find they are quite simple to use.

Hope that helps.
