pyside，Qt Designer，封装的代码和AttributeError：“ MainWindow”对象没有属性“ QtGui”

Question

I used Qt Designer to create a .ui file then pyside-uic to convert to a .py file (ui_mainWindow.py with class Ui_MainWindow ). I'm heeding the warning not to edit the .ui or .py because any changes there will be overwritten when saving updates in Qt Designer. So I have my own separate code that should be inheriting from it using the python's super functionality.

class MainWindow(QMainWindow, Ui_MainWindow):
  def __init__(self):
    super(MainWindow, self).__init__()
    self.setupUi(self)
    self.assignWidgets()
    self.show()

I'm able to update labels and respond to buttons and such but I'm not able to use the localization translation stuff. Part of the above class is this function:

def connecetSerialPushed(self):
  self.label_connected.setText(self.QtGui.QApplication.translate(self, "Connected: Yes", None, self.QtGui.QApplication.UnicodeUTF8))

If I just do a pure setText and the "Connected: Yes" string, I get no error. But doing that translation results in an error: AttributeError: 'MainWindow' object has no attribute 'QtGui'. I don't get it.. I thought I inherited everything from Ui_MainWindow including it's import of QtGui . What am I missing?

Answer 1

Inside my separate code, I did

from PySide import QtGui

and then changed the translation line to

self.label_connected.setText(QtGui.QApplication.translate("MainWindow", "Connected: Yes", None, QtGui.QApplication.UnicodeUTF8))

Thanks ray for clearing up my confusion.
