[news.eclipse.platform.swt] Re: ScrollBar auto scroll back

Hi,

ScrolledComposite should not do this, and my snippet below doesn't, so it
must be more specific to your context.  Are you able to change the snippet
to show it happening?  The snippet is based on the lines that you originally
gave, but a few had to change to make it run stand-alone.

public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new FillLayout());
    final ScrolledComposite sc = new ScrolledComposite(shell, SWT.V_SCROLL |
SWT.H_SCROLL);
    sc.setAlwaysShowScrollBars(true);
    final Composite mycomposite = new Composite(sc, SWT.NONE);
    mycomposite.setSize(800,800);
    sc.setContent(mycomposite);
    sc.setMinSize(mycomposite.computeSize(SWT.DEFAULT, SWT.DEFAULT));
//  sc.setExpandHorizontal(true);
//  sc.setExpandVertical(true);
    sc.getVerticalBar().setIncrement(sc.getVerticalBar().getIncrement() *
5);
    shell.setBounds(10, 10, 200, 200);
    shell.open();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) display.sleep();
    }
    display.dispose();
}
