Description Greg Dean CLA 2004-02-13 15:18:26 EST 
I have a Canvas where I am using scrollbars. I've added a SelectionListener to
the scrollbars and everything works fine under Windows and the Motif version on
Linux. My problem is that under the GTK version on Linux the detail member of
the SelectionEvent is always 0 and so I don't know whether its a up, down,
pageup, pagedown, or drag.

still happens in 3.0, snippet:

public static void main(String[] args) {
	Display display = new Display();
	Shell shell = new Shell(display);
	shell.setBounds(10,10,200,200);
	Canvas canvas = new Canvas (shell, SWT.V_SCROLL | SWT.BORDER);
	canvas.setBounds(10,10,100,100);
	shell.open();
	canvas.getVerticalBar().addSelectionListener(new SelectionListener() {
		public void widgetSelected(SelectionEvent e) {
			System.out.println(e.detail);
		}
		public void widgetDefaultSelected(SelectionEvent e) {}
	});
	while (!shell.isDisposed()) {
		if (!display.readAndDispatch())
			display.sleep();
	}
	display.dispose();
}

BB, you have 2.6, let's fix this thing.
Comment 9 Billy Biggs CLA 2005-02-12 12:56:16 EST 
It's a little more complicated than I would like.  The API was added to
scrollbars, but not to adjustments.  There is no API to get the scrollbars from
a scrolled window except by looking in the structure itself, and it is not clear
to me whether this is public API.

Implementing this for Slider and Scaler is no problem, since we create the range
objects ourselves.

I saw your reply on the bug(duplicate), I filed ...

Carrying forward the conversation from there, is it possible for you to give 
me a rough-estimate when we may get a fixed version ?

Thanks !

Fixed > 20050707 in HEAD for ScrollBar, Slider and Scale.  The detail will be
correctly reported if you are using GTK+ 2.6.0 or newer.
