强制QListWidget信号在发射区

Question

如何强制以下信号中的任何一个从按钮按下时触发的功能内发射？

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() 

Answer 1

您可以自己发出信号。假设self是QListWidget的一个实例：

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