Confusing SWT Style Bits in CSS Spy

[JVS94]

The CSS Rules section of CSS Spy shows the current SWT Style Bits for the selected control, but it seems to contain a lot of useless information, such as styles that are not currently supported by the selected control (e.g. SWT.RADIO here), and bits that are not styles (e.g. SWT.ERROR_MENU_NOT_POP_UP here). Why is it designed this way, and what is the use of these ?

The filter should display the correct styles bits as described in this page :

I think the idea is to remind what could be used on this widget... but ...as we are in a dynamic display, it would be better to display in bold if the style bit is set and in normal fond if not set. Using the Widget.getStyle() method that would be easy to do.

-> Good first issue
