Detailed Description

A widget that adds scrolling capabilities to its content.

Use a WScrollArea to add scrolling capabilities to another widget. When the content is bigger than the WScrollArea, scrollbars are added so that the user can still view the entire content.

Use setScrollBarPolicy() to configure if and when the scrollbars may appear.

In many cases, it might be easier to use the CSS overflow property on a WContainerWidget (see WContainerWidget::setOverflow()).

CSS

This widget is rendered using a <div> with a CSS overflow attribute. It can be styled using inline or external CSS as appropriate.
