Question

我使用qt Designer生成我的代码。我想让我的5个文本框在释放运行按钮时将5个参数传递给python函数（该函数不在此代码中）。我不太确定如何做到这一点，我对pyqt很新。

Answer 2

您可以将自己的功能连接到这样的信号：

QtCore.QObject.connect(self.Run, QtCore.SIGNAL(_fromUtf8("released()")), self.yourNewFunction)

之后你可以调用lineEdits的值：

def yourNewFunction(self):
    print self.lineEdit.text()

顺便说一句，你使用pyqt5不再支持的旧式信号。再加上新风格更容易阅读：

self.Run.pressed.connect(self.yourNewFunction)

pyqt gui将参数传递给python函数
