Use Qt Designer to create a .ui file. #. Create a python class of the same type as the widget you created in the .ui file. #. When initializing the python class, use uic to dynamically load the .ui file onto the class. Here is an example from this code: .. code-block:: python :linenos: from PyQt4 import QtGui import resources UI_FILE = 'plainTextEdit.ui' class TextWindow(QtGui.QDialog, form_class): def __init__(self, title, text): QtGui.QDialog.__init__(self, parent) resources.loadUi(UI_FILE, baseinstance=self) self.setWindowTitle(title) self.plainTextEdit.setPlainText(text) import sys app = QtGui.QApplication(sys.argv) win = TextWindow('the title', __doc__) win.show() sys.exit(app.exec_()) '''
