Bug 486756

Description Markus Knauer 2016-01-28 12:53:03 EST

I'd say we have a small regression in 3.0.1. The following snippet works fine in RAP 2.3, 3.0.0, and in 3.1.0 M4, but not with 3.0.1.

If you scroll down in the ScrolledComposite, select one of the Text widgets on the bottom with the mouse, eventually change some text, and *click with the mouse outside of any text widget*, then you are scrolled to the top of the composite. My guess is that this is a side-effect of fixing bug 471795.


public class ScrolledCompositeFocusOutJumpToTop extends AbstractEntryPoint {

    private ScrolledComposite composite;
    private Composite content;

    @Override
    protected void createContents(Composite parent) {
        composite = new ScrolledComposite(parent, SWT.H_SCROLL | SWT.V_SCROLL);
        composite.setLayoutData(new GridData(GridData.FILL, GridData.FILL, true, true));
        content = new Composite(composite, SWT.NONE);
        content.setLayout(new GridLayout(2, true));
        for (int ii = 0; ii < 200; ii++) {
            Text text = new Text(content, SWT.NONE);
            text.setText("Text Widget " + ii);
        }
        composite.setContent(content);
        composite.setExpandHorizontal(true);
        composite.setExpandVertical(true);
        composite.setAlwaysShowScrollBars(true);
        composite.setShowFocusedControl(true);
        composite.setMinSize(content.computeSize(SWT.DEFAULT, SWT.DEFAULT));
        composite.addControlListener(new ControlAdapter() {
            @Override
            public void controlResized(ControlEvent e) {
                composite.setMinSize(content.computeSize(SWT.DEFAULT, SWT.DEFAULT));
            }
        });
    }

}
