示例1: testSetCurrentLayer
# 需要导入模块: from qgis.gui import QgsLayerTreeView [as 别名]
# 或者: from qgis.gui.QgsLayerTreeView import currentLayer [as 别名]
def testSetCurrentLayer(self):
view = QgsLayerTreeView()
view.setModel(self.model)
current_layer_changed_spy = QSignalSpy(view.currentLayerChanged)
self.assertFalse(view.currentLayer())
view.setCurrentLayer(self.layer3)
self.assertEqual(view.currentLayer(), self.layer3)
self.assertEqual(len(current_layer_changed_spy), 1)
view.setCurrentLayer(self.layer)
self.assertEqual(view.currentLayer(), self.layer)
self.assertEqual(len(current_layer_changed_spy), 2)
view.setCurrentLayer(None)
self.assertFalse(view.currentLayer())
self.assertEqual(len(current_layer_changed_spy), 3)示例2: AuxiliaryLegend
