Description Remy Suen CLA 2011-03-09 07:41:01 EST 
The setDefaultButton(Button) method from Decorations will throw an IllegalArgumentException when a disposed button is set, why doesn't CTabFolder's setTopRight(Control) method do the same?

Display display = new Display();
Shell shell = new Shell(display, SWT.SHELL_TRIM);
shell.setLayout(new FillLayout());

CTabFolder folder = new CTabFolder(shell, SWT.CLOSE);
Composite c = new Composite(folder, SWT.NONE);
c.dispose();
folder.setTopRight(c);

shell.open();

while (!shell.isDisposed()) {
  if (!display.readAndDispatch())
    display.sleep();
}
display.dispose();
