41 To do:
42 - Need check-style also (stay in when pressed, pop out when unpressed).
43 - Who owns the icon(s)?
44 - Arrow buttons should auto-repeat with a timer of some kind
45 - "&Label\tTooltip\tHelptext\thttp://server/application/helponitem.html"
46 - CheckButton should send SEL_COMMAND.
47 - Default button mode:- should somehow get focus.
48 - Weird state change still possible using both keyboard and mouse if two
49 radio buttons are involved.
