示例1: testBasic
# 需要导入模块: from PySide2.QtCore import QObject [as 别名]
# 或者: from PySide2.QtCore.QObject import blockSignals [as 别名]
def testBasic(self):
'''QObject.signalsBlocked() and blockSignals()
The signals aren't blocked by default.
blockSignals returns the previous value'''
obj = QObject()
self.assert_(not obj.signalsBlocked())
self.assert_(not obj.blockSignals(True))
self.assert_(obj.signalsBlocked())
self.assert_(obj.blockSignals(False))示例2: TestSignalsBlocked
# 需要导入模块: from PySide2.QtCore import QObject [as 别名]
# 或者: from PySide2.QtCore.QObject import blockSignals [as 别名]
class TestSignalsBlocked(unittest.TestCase):
'''Test case to check if the signals are really blocked'''
