Question

我无法在QT Designer中设置GUI并将其转换为python脚本，以便在点击时执行任何操作。

目前我的代码看起来像这样：

import sys
from PyQt4.QtGui import QApplication, QDialog
from punchmenuui import *
from PyQt4.QtGui import *
from PyQt4.QtCore import pyqtSignal

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        self.closemenubutton.clicked.connect(self.closemenu)

def closemenu(self):
    sys.exit()

app = QApplication(sys.argv)
window = QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(window)
window.show()
sys.exit(app.exec_())

如你所见，它很简单。我在布局.py文件中指定了一个按钮，我试图抓住＆＃34;点击＆＃34;从它发出信号并触发一个干净的退出事件。问题是：似乎没有任何成就。我尝试过新旧风格的PyQt信号/插槽绑定都无济于事。

有人能发现我做错了吗？

编辑：

感谢你们迄今为止的回复。我已经尝试了所有答案的所有组合，但到目前为止它们都没有奏效。我当前的启动器.py脚本代码如下：

import sys
from PyQt4.QtGui import QApplication, QDialog
from punchmenuui import *
from PyQt4.QtGui import *
from PyQt4.QtCore import pyqtSignal

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        self.closemenubutton.clicked.connect(self.closemenu)

    def closemenu():
        sys.exit()

app = QApplication(sys.argv)
window = QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(window)
window.show()
sys.exit(app.exec_())

和QT-Designed ui的脚本是：

这是否有助于确定不应该做的事情？

Answer 1

您的closemenu功能需要成为您班级的一部分。

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        self.closemenubutton.clicked.connect(self.closemenu)

    # Notice this has been brought into the class
    def closemenu(self):
        sys.exit()

您没有提供您的UI文件，因此我无法执行完全测试，但我可以向您展示这是一个简单的示例：

此代码创建一个按钮：

导入系统来自PyQt4导入QtGui，QtCore

class Window(QtGui.QWidget):
    def __init__(self):
        QtGui.QWidget.__init__(self)
        self.closebutton = QtGui.QPushButton('Exit', self)
        self.closebutton.clicked.connect(self.exit_button)
        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.closebutton)

    def exit_button(self):
        sys.exit()

if __name__ == '__main__':
    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(app.exec_())

看起来像这样：

Example Button

单击该按钮时，应用程序将关闭，退出状态为0（一个干净的退出）

C:\Sandbox>python exit_button.py
C:\Sandbox>echo %ERRORLEVEL%
0

无论底层问题是什么，我都可以通过切换到使用Eric IDE和Qt设计器并遵循本教程来解决问题：http://eric-ide.python-projects.org/tutorials/MiniBrowser/index.html以了解开发环境的好处＆＃34} 34;在我之前使用的基本上记事本的数量！

当你可以看到你附加的手柄时，定义动作会容易得多！阅读此内容的其他新手 - 遵循该指南，它让我从面向对象的编程和GUI开始。
