The Record associated * to the attribute is generated on demand. To have a completly * uniform history we must create a special Slot from the root * Record, unlike others this Slot contains directly the Record * and not the attribute pointer it has been generated from. * * When an Inspector windows is closed by the window manager, * the widget is not simply hidden, it is fully destroyed * (see the QWidget \c Qt::WA_DeleteOnClose attribute). Thus, pointers * to an Inspector Widget are not to be kept. * * Any number of Inspector could be created simultanously, even * on the same datas. Slot & Record beeing on demand, expandables, * objects. */ //! \name Constructors & Destructors // \{ /*! \function HInspectorWidget::HInspectorWidget(QWidget* parent=NULL); * Construct a HInspectorWidget.
