Bug 12195 TestCase creation wizard: no progress when pressing super button
There is no progress shown in the wizard when pressing the browse button for selecting the super class. This is not consistent with the New Class wizard.

fClassToTestButton= new Button(composite, SWT.PUSH);
		fClassToTestButton.setText(Messages.getString("NewTestClassWizPage.class_to_test.browse")); 
		fClassToTestButton.setEnabled(true);
		fClassToTestButton.addSelectionListener(new SelectionListener() {
			public void widgetDefaultSelected(SelectionEvent e) {
				classToTestButtonPressed();
			}
			public void widgetSelected(SelectionEvent e) {
				classToTestButtonPressed();
			}
		});

		gd.widthHint = SWTUtil.getButtonWidthHint(fClassToTestButton);		
		fClassToTestButton.setLayoutData(gd);

			return null;
