[news.eclipse.platform.swt] Re: how to make a scrollable view ?

["Horváth, Csaba" <hcs33@xxxxxxxxxxxxxxxx>]

Hi,

The following code works for me:

 public void createPartControl(Composite parent)
 {
    parent.setLayout(new FillLayout());
    ScrolledComposite sc1 = new ScrolledComposite(parent,SWT.H_SCROLL |
SWT.V_SCROLL | SWT.BORDER);
    Composite comp = new Composite(sc1, SWT.NONE);
    comp.setLayout(new FillLayout());
    new Label(comp, SWT.NONE).setText("text");
    new Button(comp, SWT.NONE).setText("button");
    sc1.setContent(comp);
    comp.setSize(comp.computeSize(SWT.DEFAULT, SWT.DEFAULT));
 }

It displays both the label and the text.

HTH,
Regards,
Csaba
