這是什麼,我建議我自己,並不一定是最好的單元測試的解決方案更詳盡的版本,但我認爲這將是感興趣的其他人遇到這樣的:
發佈卡洛斯Scheidegger在PyQt的郵件列表(http://thread.gmane.org/gmane.comp.python.pyqt-pykde/9242/focus=9245)
_oldConnect = QtCore.QObject.connect
_oldDisconnect = QtCore.QObject.disconnect
_oldEmit = QtCore.QObject.emit
def _wrapConnect(callableObject):
"""Returns a wrapped call to the old version of QtCore.QObject.connect"""
@staticmethod
def call(*args):
callableObject(*args)
_oldConnect(*args)
return call
def _wrapDisconnect(callableObject):
"""Returns a wrapped call to the old version of QtCore.QObject.disconnect"""
@staticmethod
def call(*args):
callableObject(*args)
_oldDisconnect(*args)
return call
def enableSignalDebugging(**kwargs):
"""Call this to enable Qt Signal debugging. This will trap all
connect, and disconnect calls."""
f = lambda *args: None
connectCall = kwargs.get('connectCall', f)
disconnectCall = kwargs.get('disconnectCall', f)
emitCall = kwargs.get('emitCall', f)
def printIt(msg):
def call(*args):
print msg, args
return call
QtCore.QObject.connect = _wrapConnect(connectCall)
QtCore.QObject.disconnect = _wrapDisconnect(disconnectCall)
def new_emit(self, *args):
emitCall(self, *args)
_oldEmit(self, *args)
QtCore.QObject.emit = new_emit
只需調用enableSignalDebugging(emitCall = FOO)窺探你的信號,直到 你病要你的胃:)
讓Phil(PyQt的作者)知道它是必需的。他會添加它或建議一種解決方法。 – 2010-01-12 17:20:42
