Small Mega-Widgets

These are small but rather useful mega-widgets. We just mention them briefly:

• A ScrollBox is a scrollable widget inside a box scroll bars attached.
• A Separator is a frame with relief and borderwidth, to optically separate widgets.
• A SelectBox is a container for a group of buttons, one of which can be nominated as default button.
• An IconBar is a bar containing a row of buttons (ideally of the same size showing an image, but this is not enforced.)
