我正在尝试在我的主窗口上连接一个按钮以在我单击它时打开一个新的小部件。但是每次我运行程序时都会出现这个错误：

AttributeError：“dataAcquisition”对象没有属性“gpioButton”

如果有人可以提供帮助，我将不胜感激。

这是我的代码：

from PyQt4 import QtCore, QtGui
from mainwindow import Ui_MainWindow
from gpiodialog import Ui_GPIODialog
import sys

class gpioDialog(QtGui.QDialog, Ui_GPIODialog):
    def __init__(self, parent=None):
        QtGui.QDialog.__init__(self, parent)
        flags = QtCore.Qt.Drawer | QtCore.Qt.WindowStaysOnTopHint
        self.setWidowFlags(flags)
        self.ui = Ui_GPIODialog
        self.ui.setupUi(self)

        self.gpioOKButton.clicked.connect(self.acceptOKButtonClicked)
    def acceptOKButtonClicked(self):
        self.close()        


class dataAcquisition(QtGui.QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        QtGui.QMainWindow.__init__(self, parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

        self.gpioButton.clicked.connect(self.gpioButton_clicked)
        self.popGPIO = gpioDialog()

    def gpioButton_clicked(self):
        self.popGPIO.show()

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    MainWindow = dataAcquisition()
    MainWindow.show()
    sys.exit(app.exec_())

您为 ui 创建了一个单独的命名空间，因此您需要像这样访问按钮：

    self.ui.gpioButton.clicked.connect(self.gpioButton_clicked)

但是，如果您希望将所有小部件作为窗口的属性，请执行以下操作：

class gpioDialog(QtGui.QDialog, Ui_GPIODialog):
    def __init__(self, parent=None):
        super(gpioDialog, self).__init__(parent)
        flags = QtCore.Qt.Drawer | QtCore.Qt.WindowStaysOnTopHint
        self.setWindowFlags(flags)
        self.setupUi(self)
        self.gpioOKButton.clicked.connect(self.acceptOKButtonClicked)


class dataAcquisition(QtGui.QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(dataAcquisition, self).__init__(parent)
        self.setupUi(self)
        self.gpioButton.clicked.connect(self.gpioButton_clicked)
        self.popGPIO = gpioDialog()
