示例1: testSignal
# 需要导入模块: from qgis.gui import QgsProjectionSelectionWidget [as 别名]
# 或者: from qgis.gui.QgsProjectionSelectionWidget import show [as 别名]
def testSignal(self):
w = QgsProjectionSelectionWidget()
w.show()
spy = QSignalSpy(w.crsChanged)
w.setCrs(QgsCoordinateReferenceSystem('EPSG:3111'))
self.assertEqual(w.crs().authid(), 'EPSG:3111')
self.assertEqual(len(spy), 1)
# setting the same crs doesn't emit the signal
w.setCrs(QgsCoordinateReferenceSystem('EPSG:3111'))
self.assertEqual(len(spy), 1)示例2: QgsProjectionSelectionWidget
# 需要导入模块: from qgis.gui import QgsProjectionSelectionWidget [as 别名]
# 或者: from qgis.gui.QgsProjectionSelectionWidget import show [as 别名]
