Function Documentation

int mitkVtkWidgetRenderingTest	(	int	,
		char *	[]
	)

Test for class mitk::VtkWidgetRendering (for rendering vtkWidgets on the screen)

argc and argv are the command line parameters which were passed to the ADD_TEST command in the CMakeLists.txt file. For the automatic tests, argv is either empty for the simple tests or contains the filename of a test image for the image tests (see CMakeLists.txt).
