How to import mainwindow (.ui file) using PySide

I'm doing a python project and design its interface using PySide. The problem is how can I import mainwindow (.ui file) from Qt Designer using PySide. My class is inherited from QtGui.QMainWindow.

Thank you for your answer. ^^

Solution

Let's say the top-level object in Qt Designer is named MainWindow.

When you use pyside-uic to generate the GUI module, it will create a class called Ui_MainWindow. It is this class that you need to import into your main application. The imported class has a setupUi method, which is used to inject the GUI into an instance of the top-level class from Qt Designer. So the basic code to do this should look something like this:

from PySide import QtCore, QtGui
from mainwindow import Ui_MainWindow

class MainWindow(QtGui.QMainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self)
        self.ui = Ui_MainWindow.setupUi(self)

With that in place, you can access the widgets from Qt Designer like this:

       # connect a button to its handler
       self.ui.pushButton.clicked.connect(self.handleButtonClicked)

To run the application, you can do:

if __name__ == '__main__':

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