/** @brief Reimplementation of TQWidget emitting a signal if resized.
|
|
*
|
|
* This class is equalt to TQWidget 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 TQGLWidget::resizeGL() method of the GL
|
|
* widgets (PendulumGLWidget::resizeGL(), RotationGLWidget::resizeGL()) which
|
|
* really resizes the GL scenery. */
