I don't believe there is a way to get the size before the change. I do
not believe that there is much requirement for that. If you are looking
for a more elegant solution, you would have to reimplement GtkViewport
or GtkScrolledWindow to keep track of the visible view now and before.

Well, since resizing the widget by itself does not do any scrolling,
whichever value you get from the adjustment _is_ the current scroll
value. In the same way you have the function *_get_upper(), you have
*_get_lower() and *_get_value()... Just change the computation however
you need it to be.

Bind a callback to the "size-allocate" signal of the scrolled window:
#include
void cb_autoscroll_to_end( GtkWidget* widget, GtkAllocation* allocation,
gpointer user_data)
{
GtkAdjustment*vericalAdjust;
GtkAllocation hscrollAlloc;
GtkWidget *hscrollBar; /* the h
