Question

我正在制作一个只包含按钮的简单GUI。我决定用PyQt Designer来做。

我决定Designer生成的UI将在一个文件中，其余的将在另一个将导入UI的模块中。

PyQt Designer生成的文件是：

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    def _fromUtf8(s):
        return s

try:
    _encoding = QtGui.QApplication.UnicodeUTF8
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig)

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName(_fromUtf8("Form"))
        Form.resize(326, 232)
        self.pushButton = QtGui.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(104, 30, 101, 31))
        self.pushButton.setObjectName(_fromUtf8("pushButton"))

        self.retranslateUi(Form)

    def retranslateUi(self, Form):
        Form.setWindowTitle(_translate("Form", "Form", None))
        self.pushButton.setText(_translate("Form", "PushButton", None))

导入它的主文件如下所示：

import sys
from PyQt4 import QtCore, QtGui
from stacko import Ui_Form

class test(Ui_Form):
    self.pushButton.connect.clicked(self.onClick)
    def onClick(self):
        print "clicked!"

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    Form = QtGui.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

我想要点击按钮时会打印出“点击！”。出于某种原因，它不适合我。我在类/子类和OOP上阅读了很多内容，但我仍然无法使其正常工作。

它引发了错误：NameError: name 'self' is not defined

以下是您的主要模块应该是什么样的：

import sys
from PyQt4 import QtCore, QtGui
from stacko import Ui_Form

class Test(QtGui.QWidget, Ui_Form):
    def __init__(self):
        super(Test, self).__init__()
        self.setupUi(self)
        self.pushButton.clicked.connect(self.onClick)

    def onClick(self):
        print "clicked!"

if __name__ == "__main__":

    app = QtGui.QApplication(sys.argv)
    window = Test()
    window.show()
    sys.exit(app.exec_())
