How to save a form from Qt Designer as a standalone app?

Question

I have created a mock-up of a form in Qt Designer, and now I would like to save the form as a (exe?) file so that it can be run on the computer.

Would I use \'Python

To create a standalone app with PyInstaller follow these steps:

1. Save this code as your MyWidget.ui file:

   
   
    MainWindow
    
     
      
       0
       0
       147
       125
      
     
     
      MainWindow
     
     
      
       
        
       
       
        
         
          Click Me
         
        
       
      
     
     
      
       
        0
        0
        147
        25
       
      
      
       
        Menu
       
      
      
     
     
    
    
    
   
   

2. Compile your MyWidget.ui file into Ui_MyWidget.py using pyuic4 with this command from your OS shell command-line:

   pyuic4 "/path/to/MyWidget.ui" -o "Ui_MyWidget.py"
   

   This command will create a Ui_MyWidget.py file in your current directory with this contents:

   # -*- coding: utf-8 -*-
   
   # Form implementation generated from reading ui file 'MyWidget.ui'
   #
   # Created: Fri Dec 28 03:45:13 2012
   #      by: PyQt4 UI code generator 4.7.3
   #
   # WARNING! All changes made in this file will be lost!
   
   from PyQt4 import QtCore, QtGui
   
   class Ui_MainWindow(object):
       def setupUi(self, MainWindow):
           MainWindow.setObjectName("MainWindow")
           MainWindow.resize(147, 125)
           self.centralwidget = QtGui.QWidget(MainWindow)
           self.centralwidget.setObjectName("centralwidget")
           self.verticalLayout = QtGui.QVBoxLayout(self.centralwidget)
           self.verticalLayout.setObjectName("verticalLayout")
           self.lineEdit = QtGui.QLineEdit(self.centralwidget)
           self.lineEdit.setObjectName("lineEdit")
           self.verticalLayout.addWidget(self.lineEdit)
           self.pushButton = QtGui.QPushButton(self.centralwidget)
           self.pushButton.setObjectName("pushButton")
           self.verticalLayout.addWidget(self.pushButton)
           MainWindow.setCentralWidget(self.centralwidget)
           self.menubar = QtGui.QMenuBar(MainWindow)
           self.menubar.setGeometry(QtCore.QRect(0, 0, 147, 25))
           self.menubar.setObjectName("menubar")
           self.menuMenu = QtGui.QMenu(self.menubar)
           self.menuMenu.setObjectName("menuMenu")
           MainWindow.setMenuBar(self.menubar)
           self.statusbar = QtGui.QStatusBar(MainWindow)
           self.statusbar.setObjectName("statusbar")
           MainWindow.setStatusBar(self.statusbar)
           self.menubar.addAction(self.menuMenu.menuAction())
   
           self.retranslateUi(MainWindow)
           QtCore.QMetaObject.connectSlotsByName(MainWindow)
   
       def retranslateUi(self, MainWindow):
           MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow", "MainWindow", None, QtGui.QApplication.UnicodeUTF8))
           self.pushButton.setText(QtGui.QApplication.translate("MainWindow", "Click Me", None, QtGui.QApplication.UnicodeUTF8))
           self.menuMenu.setTitle(QtGui.QApplication.translate("MainWindow", "Menu", None, QtGui.QApplication.UnicodeUTF8))
   

3. Save this code as your MyWidget.py file:

   #!/usr/bin/env python
   #-*- coding:utf-8 -*-
   
   from PyQt4 import QtCore, QtGui
   from Ui_MyWidget import Ui_MainWindow
   
   class MyWidget(QtGui.QMainWindow, Ui_MainWindow):
       def __init__(self, parent=None):
          super(MyWidget, self).__init__(parent)
   
          self.setupUi(self)
   
       @QtCore.pyqtSlot()
       def on_pushButton_clicked(self):
           self.lineEdit.setText("A Qt standalone app!")
   
   if __name__ == '__main__':
       import sys
   
       app = QtGui.QApplication(sys.argv)
       window = MyWidget()
       window.resize(300, 30)
       window.show()
       sys.exit(app.exec_())
   

4. Check that you can run MyWidget.py without errors (MyWidget.py and Ui_MyWidget.py need to be in the same folder), and once done configuring PyInstaller (checkout the README file) from your OS shell command-line cd into the pyinstaller directory and run this command:

   python pyinstaller.py --onefile '/path/to/MyWidget.py'
   

5. Look for a folder called MyWidget in the pyinstaller folder, inside the dist folder is your standalone Qt app.
