/**
* @brief The QWidgetAnimation class
* This class animate the show and hide function of a QWidget.
*
* The role of @behavior is to calcul as best the animation process when widget is show.
* Because this class don't change the current and final size of the widget but her maximum size during the animation process,
* we must to know in advance the final size of the widget.
* Behavior minimumSizeHint : the final size of the widget will be his minimum size hint.
* Behavior availableSpace : the final size of widget will be the available size of her parent.
* Since parent can have other widgets you can add a QVector of widget to subtract of the final size.
* Because we suppose the animated widget will take the maximum available space, we subtract the minimum size hint of widgets in QVector.
* Behavior lastSize : The widget will have the same size as the last time he was showed.
