Hello,
I use a ScrolledComposite which contents a ExpandableComposite, which is closed when I open my editor.I would like that when I expand my composite (which is longer than the ScrolledComposite), a scrollbar appears in the ScrolledComposite.
I use a listener but nothing happens.

mySection.addExpansionListener(new ExpansionAdapter() {
	public void expansionStateChanged(ExpansionEvent e) {
		form.reflow(true);
		parent.layout();
	}
});

Someone would have an idea?
Thx.

I find a solution to my problem.
I just use scrollComposite.setExpandHorizontal(true) on my scrollComposite. And in my method expansionStateChanged of my ScrollComposite's listener, I don't use the reflow method, but :

myComposite.setSize(myComposite.computeSize(SWT.DEFAULT, SWT.DEFAULT));
myComposite.layout();

where myComposite is the composite contained by the scrolledComposite, and which contains the expendable composite.

I hope that will help someone.
David.
