Detecting scrolling from a scroll window

[asnth]

So i've got a GtkTextView inside a scrolled window. Using the "scroll_event" signal i can detect the roll of a mouse wheel as the window is scrolled. But when i scroll the window by clicking and dragging the scrollbar or by clicking the scrollbar buttons, nothing happens. How can i detect these actions?

Perhaps you can use the changed signal of the scrolled window's gtkadjustment widgets.

It worked! thanks.
For the benefit of other readers, here's how:

$vadj = $scrollwindow -> get_vadjustment(); // get the vertical adjustment widget
$vadj -> connect ('value-changed', array (&$this, 'scroll_it') ); // listen for a signal change from the scrolling

function scroll_it ($item, $event) {

echo "Detecting scrolling now\n";
}

I used it to make two separate textviews scroll simultaneously, by setting both textviews to have the same vadjustment.
