示例1: _testRegistry
# 需要导入模块: from qgis.gui import QgsSourceSelectProviderRegistry [as 别名]
# 或者: from qgis.gui.QgsSourceSelectProviderRegistry import providersByKey [as 别名]
def _testRegistry(self, registry):
registry.addProvider(ConcreteSourceSelectProvider())
registry.addProvider(ConcreteSourceSelectProvider2())
# Check order
self.assertEqual(['MyTestProviderKey', 'MyName'], [p.name() for p in registry.providers() if p.providerKey().startswith('MyTestProviderKey')])
registry = QgsSourceSelectProviderRegistry()
registry.addProvider(ConcreteSourceSelectProvider())
registry.addProvider(ConcreteSourceSelectProvider2())
# Check order
self.assertEqual(['MyTestProviderKey', 'MyName'], [p.name() for p in registry.providers() if p.providerKey().startswith('MyTestProviderKey')])
# Get provider by name
self.assertTrue(registry.providerByName('MyTestProviderKey'))
self.assertTrue(registry.providerByName('MyName'))
# Get not existent by name
self.assertFalse(registry.providerByName('Oh This Is Missing!'))
# Get providers by data provider key
