## Detailed Description

The QWSEmbedWidget class enables embedded top-level widgets in Qt for Embedded Linux.

Note that this class is only available in Qt for Embedded Linux.

QWSEmbedWidget inherits QWidget and acts as any other widget, but in addition it is capable of embedding another top-level widget.

An example of use is when painting directly onto the screen using the QDirectPainter class. Then the reserved region can be embedded into an instance of the QWSEmbedWidget class, providing for example event handling and size policies for the reserved region.

All that is required to embed a top-level widget is its window ID.

See also Qt for Embedded Linux Architecture.
