PySide: creating a checklist

I am trying to create a checklist in PySide. These flags will be inside the grid, which is inside the frame.

Since I need more than a hundred flags, I thought it was best to keep these flags in a list. There class Ui_MainWindow(object):is def setupUi(self, MainWindow):inside, and inside this I call my method myChangeswith self.myChanges(MainWindow, self.customCheckBoxes, self.frame, self.gridLayout). Right above this, I am creating an empty list to try to save objects withself.customCheckBoxes = []

Outside the class Ui_MainWindow, I have a separate class with a name CreateCheckboxthat tries to check the box under the frame, set the name of the object, add it to the spot in the grid and set its text. From what I can say, he can perform the first two perfectly, a problem arises with the line self.grid.addWidget(self.checkBox, gridPlace, 1, 1, 1). In particular, the problem with gridand causes this error:AttributeError: 'CreateCheckbox' object has no attribute 'grid'

My questions:

  • Do I use the grid in any other way?
  • Am I not allowed to use the dots around the grid when I pass it?
  • How to fix this problem so that all the flags go down one line of the file on the grid?
  • Is my class CreateCheckboxor my myChangesmethod in the wrong place / where would I put them?

Edit: I think I found what I did wrong. in class CreateCheckboxshould not be self.in self.grid.addWidget(self.checkBox, gridPlace, 1, 1, 1), because the grid is not an instance of the classCreateCheckbox

Edit 2: just in case someone wants the text to work put quotation marks around MainWindowin self.checkBox.setText(QtGui.QApplication.translate(MainWindow, text, None, QtGui.QApplication.UnicodeUTF8))so you self.checkBox.setText(QtGui.QApplication.translate("MainWindow", text, None, QtGui.QApplication.UnicodeUTF8))

Here is the full code:

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))

        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_())
