示例1: testShowingNotSetOption

# 或者: from qgis.gui.QgsProjectionSelectionWidget import optionVisible [as 别名]
def testShowingNotSetOption(self):
""" test showing the not set option """
w = QgsProjectionSelectionWidget()
# start with an invalid CRS
w.setCrs(QgsCoordinateReferenceSystem())
# add the not-set option
