示例1: testEmbeddedGroup
# 需要导入模块: from qgis.core import QgsProject [as 别名]
# 或者: from qgis.core.QgsProject import mapLayer [as 别名]
def testEmbeddedGroup(self):
testdata_path = unitTestDataPath('embedded_groups') + '/'
prj_path = os.path.join(testdata_path, "project2.qgs")
prj = QgsProject()
prj.read(prj_path)
layer_tree_group = prj.layerTreeRoot()
self.assertEqual(len(layer_tree_group.findLayerIds()), 2)
for layer_id in layer_tree_group.findLayerIds():
name = prj.mapLayer(layer_id).name()
self.assertTrue(name in ['polys', 'lines'])
if name == 'polys':
self.assertTrue(layer_tree_group.findLayer(layer_id).itemVisibilityChecked())
elif name == 'lines':
self.assertFalse(layer_tree_group.findLayer(layer_id).itemVisibilityChecked())示例2: testEmbeddedGroup
