+/** @brief Reimplementation of QWidget emitting a signal if resized.
+ *
+ * This class is equalt to QWidget except for the fact that the signal resized()
+ * is emitted if the widget gets resized.  By this signaling mechanism it is
+ * possible to resize the embedded GL area object within the screen saver setup
+ * dialog.
+ *
+ * In the constructor of the dialog widget (KPendulumSetup::KPendulumSetup(),
+ * KRotationSetup::KRotationSetup()) the signal SsPreviewArea::resized() is
+ * connected with a slot of the screensaver class
+ * (KPendulumSaver::resizeGlArea(), KRotationSaver::resizeGlArea()).  This slot
+ * function calls the reimplemented QGLWidget::resizeGL() method of the GL
+ * widgets (PendulumGLWidget::resizeGL(), RotationGLWidget::resizeGL()) which
+ * really resizes the GL scenery. */
