强制QListWidget信号在pyside中发出

Question

如何强制从按钮按下的功能中发出以下任何信号？

def currentItemChanged (current, previous)
def currentRowChanged (currentRow)
def currentTextChanged (currentText)
def itemActivated (item)
def itemChanged (item)
def itemClicked (item)
def itemDoubleClicked (item)
def itemEntered (item)
def itemPressed (item)
def itemSelectionChanged ()

您可以自己发出信号。假设self是QListWidget的实例：

self.itemActivated.emit(myItem)
self.currentTextChanged.emit("some new text")
