Question

我试图在PySide中创建一个复选框列表。这些复选框将驻留在框架内的网格中。

因为我需要超过一百个复选框，我认为最好将这些复选框存储在列表中。在class Ui_MainWindow(object):内def setupUi(self, MainWindow):，我可以使用myChanges调用我的方法self.myChanges(MainWindow, self.customCheckBoxes, self.frame, self.gridLayout)。在我的上方，我创建一个空列表，尝试使用self.customCheckBoxes = []

存储对象

在Ui_MainWindow类之外，我有一个名为CreateCheckbox的单独类，它尝试在框架下创建一个复选框，设置对象的名称，将其添加到网格并设置它的文本。从我所知道的，它可以完美地执行前两个，问题由行self.grid.addWidget(self.checkBox, gridPlace, 1, 1, 1)引起。更具体地说，它在grid时出现问题并引发此错误：AttributeError: 'CreateCheckbox' object has no attribute 'grid'

我的问题是：

我是以错误的方式使用网格吗？
我通过时不允许在网格周围使用点？
如何解决此问题，以便所有复选框都沿网格向下单个文件行？
我的CreateCheckbox课程或我的myChanges方法是在错误的地方/我会把它们放在哪里？

编辑：我想我发现了我做错了什么。在class CreateCheckbox中，self.中应该没有self.grid.addWidget(self.checkBox, gridPlace, 1, 1, 1)，因为网格不是CreateCheckbox类的实例

编辑2：万一有人想让文字正常工作，请在MainWindow周围加上引号 self.checkBox.setText(QtGui.QApplication.translate(MainWindow, text, None, QtGui.QApplication.UnicodeUTF8))所以你有 self.checkBox.setText(QtGui.QApplication.translate("MainWindow", text, None, QtGui.QApplication.UnicodeUTF8))

这里是完整的代码：

from PySide import QtCore, QtGui


class Ui_MainWindow(object):
    def myChanges(self, MainWindow, checkboxes, frame, grid):
        for j in range(100):
            checkboxes.append(CreateCheckbox(MainWindow, frame, grid, "Test", j))

    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtGui.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.frame = QtGui.QFrame(self.centralwidget)
        self.frame.setGeometry(QtCore.QRect(180, 90, 371, 311))
        self.frame.setFrameShape(QtGui.QFrame.StyledPanel)
        self.frame.setFrameShadow(QtGui.QFrame.Raised)
        self.frame.setObjectName("frame")
        self.gridLayout_2 = QtGui.QGridLayout(self.frame)
        self.gridLayout_2.setObjectName("gridLayout_2")
        self.gridLayout = QtGui.QGridLayout()
        self.gridLayout.setObjectName("gridLayout")
        self.gridLayout_2.addLayout(self.gridLayout, 0, 0, 1, 1)
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtGui.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtGui.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

        # Create list holding checkbox objects
        self.customCheckBoxes = []
        self.myChanges(MainWindow, self.customCheckBoxes, self.frame, self.gridLayout)

    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow", "MainWindow", None, QtGui.QApplication.UnicodeUTF8))


class CreateCheckbox(object):
    def __init__(self, MainWindow, frame, grid, text, gridPlace):
        # 1. Create under appropriate frame
        self.checkBox = QtGui.QCheckBox(frame)
        # 2. Set its name
        #    Although the designer does this, pretty sure this is unneccesary
        self.checkBox.setObjectName(chr(gridPlace))
        # 3. Add it to the appropriate spot in the grid
        self.grid.addWidget(self.checkBox, gridPlace, 1, 1, 1)
        # 4. Set text that user sees
        # For now, I'm just sending 'Test'
        self.checkBox.setText(QtGui.QApplication.translate(MainWindow, text, None, QtGui.QApplication.UnicodeUTF8))

if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    MainWindow = QtGui.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

错误告诉您CreateCheckbox没有名为grid的成员。

我认为您的意思是引用传递给类构造函数的grid变量（__init__）

class CreateCheckbox(object):
    def __init__(self, MainWindow, frame, grid, text, gridPlace):
        #################
        self.grid = grid
        #################

        # 1. Create under appropriate frame
        self.checkBox = QtGui.QCheckBox(frame)
        # 2. Set its name
        #    Although the designer does this, pretty sure this is unneccesary
        self.checkBox.setObjectName(chr(gridPlace))
        # 3. Add it to the appropriate spot in the grid
        self.grid.addWidget(self.checkBox, gridPlace, 1, 1, 1)
        # 4. Set text that user sees
        # For now, I'm just sending 'Test'
        self.checkBox.setText(QtGui.QApplication.translate(MainWindow, text, None, QtGui.QApplication.UnicodeUTF8))

此代码让我相信您希望CreateCheckBox返回QCheckBox个对象，但这不是您正在做的事情。

def myChanges(self, MainWindow, checkboxes, frame, grid):
    for j in range(100):
        checkboxes.append(CreateCheckbox(MainWindow, frame, grid, "Test", j))

CreateCheckbox应该是一个返回QCheckBox对象的函数或一个派生自QCheckBox的类。

def CreateCheckbox(MainWindow, frame, grid, text, gridPlace):
        # 1. Create under appropriate frame
        checkBox = QtGui.QCheckBox(frame)
        # 2. Set its name
        #    Although the designer does this, pretty sure this is unneccesary
        checkBox.setObjectName(chr(gridPlace))
        # 3. Add it to the appropriate spot in the grid
        grid.addWidget(checkBox, gridPlace, 1, 1, 1)
        # 4. Set text that user sees
        # For now, I'm just sending 'Test'
        checkBox.setText(QtGui.QApplication.translate(MainWindow, text, None, QtGui.QApplication.UnicodeUTF8))
        return checkBox

或者您可以将CreateCheckbox设为方法：

class Ui_MainWindow(object):
    def CreateCheckbox(self, MainWindow, frame, grid, text, gridPlace):
        # 1. Create under appropriate frame
        checkBox = QtGui.QCheckBox(frame)
        # 2. Set its name
        #    Although the designer does this, pretty sure this is unneccesary
        checkBox.setObjectName(chr(gridPlace))
        # 3. Add it to the appropriate spot in the grid
        grid.addWidget(checkBox, gridPlace, 1, 1, 1)
        # 4. Set text that user sees
        # For now, I'm just sending 'Test'
        checkBox.setText(QtGui.QApplication.translate(MainWindow, text, None, QtGui.QApplication.UnicodeUTF8))
        return checkBox
