Bug 67132 Styled text example loses the text style when changing any style flag
RC2 Custom Controls example. If I put part of the text in Bold and then change the any style flag, the bolded text is reverted to normal. I believe this is a bug in the example, but this needs to be confirmed.

styledText = new StyledText (styledTextGroup, style);
		styledText.setText (ControlExample.getResourceString("Example_string"));
		styledText.append ("\n");
		styledText.append (ControlExample.getResourceString("One_Two_Three"));
	}
	
	/**
	 * Creates the "Style" group.

	void createStyleGroup() {
		super.createStyleGroup();
	
		
		wrapButton = new Button (styleGroup, SWT.CHECK);
		wrapButton.setText ("SWT.WRAP");
		readOnlyButton = new Button (styleGroup, SWT.CHECK);
		readOnlyButton.setText ("SWT.READ_ONLY");
		fullSelectionButton = new Button (styleGroup, SWT.CHECK);
		fullSelectionButton.setText ("SWT.FULL_SELECTION");
	}
	
	/**

		final Display display = controlGroup.getDisplay ();
		styledTextStyleGroup = new Group (controlGroup, SWT.NONE);
		styledTextStyleGroup.setText (ControlExample.getResourceString ("StyledText_Styles"));
		styledTextStyleGroup.setLayout (new GridLayout(5, false));
