pyside连接错误“RuntimeError:无法连接信号clicked()"； [英] pyside connection Error "RuntimeError: Failed to connect signal clicked()"

问题描述

from PySide.QtCore import *
from PySide.QtGui import *

import sys
import stackwid

class Dialog(QDialog,stackwid.Ui_Dialog):

    def __init__(self,parent = None):
        super(Dialog,self).__init__(parent)
        self.setupUi(self)


        self.camButton.clicked.connect(self.set())


    def set(self):

        self.stackedWidget.setCurrentIndex(1)


app = QApplication(sys.argv)
form = Dialog()
form.show()
app.exec_()

我想将 camButton(PushButton) 发出的 clicked() 信号连接到插槽，这是一个函数 set().这只是不运行.

I wanted to connect clicked() signal emitted by camButton(PushButton) to slot which is a function set().This just does not run .

RuntimeError: Failed to connect signal clicked()

推荐答案

您没有将信号连接到 set() 函数，而是连接到它的返回值.您只需要删除括号，然后它应该可以工作:

You don't connect the signal to your set()-function, but to it's return value. You just need to remove the parenthesis, then it should work:

self.camButton.clicked.connect(self.set)
