* @class vtkQtInitialization
|
|
* @brief Initializes a Qt application.
|
|
*
|
|
*
|
|
* Utility class that initializes Qt by creating an instance of
|
|
* QApplication in its ctor, if one doesn't already exist.
|
|
* This is mainly of use in ParaView with filters that use Qt in
|
|
* their implementation - create an instance of vtkQtInitialization
|
|
* prior to instantiating any filters that require Qt.
