A ScrolledWindow is a Bin subclass; it's a container that accepts a single child widget. ScrolledWindow adds scrollbars to the child widget and optionally draws a beveled frame around the child widget.
The ScrolledWindow works in two ways. Some Widgets have native
scrolling support; these widgets have "slots" for Adjustment
objects.
For Widgets that lack native scrolling support the Viewport
Widget acts as an adaptor class, implementing scrollability for
child Widgets that lack their own scrolling capability.
If a Widget has native scrolling capabilities it can be added with the
add
method. If a Widget does not, you must first add the
Widget to a Viewport
and then add the Viewport
to the ScrolledWindow. The convenience method
addWithViewport
does exactly this, so you can ignore the
presence of the Viewport
.
The position of the scrollbars is controlled by the scroll adjustments.
See Adjustment
for details on how to determine the position
of the layout.
