Hi.
I created a new view part like properties view. When the createPartControl
is called I create a Empty composite so that it can be filled with other
contents later depending on the selected item. However, when I changed the
content of this composite the view does not show added contents. I tried
to use refresh or update from the Composite, but that didn't work.
However, when I resize this view manually suddenly the contents show up. I
am trying to find out how I can update the current view programmatically
because whenever the selection is changed I need to put new contents to
the view. Any help would be appreciated.
Following is a test view. I want to add new label everytime the selection
is changed, but the content does not show up until I manually resize the
view from the workbench.

private Composite pageContainer;
@Override

getSite().getPage().addSelectionListener(this);
pageContainer = createPageContainer(parent);

Composite composite = new Composite(parent, SWT.NULL);

formData.left = new FormAttachment(0, 0);

composite.setLayout(layout);
composite.setLayoutData(formData);
composite.setBackground(new Color(null, 255, 255, 255));
}
return composite;
}
@Override
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
Label label = new Label(pageContainer, SWT.NULL);
label.setText(selection.toString());
pageContainer.update();
pageContainer.redraw();
