public class ScrolledWindow extends Bin
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.
