How can I resize the main window depending on screen resolution using PyQt

I have a main window with three frames.The top frame consists of the header and the bottom frame consists of the footer. I designed it using the `PyQt4` designer.The window looks fine when I run it on my laptop with a screen resolution of `1920*1080`. But when I check the same on other resolutions like `1600*900` the footer gets cut off. I wanted to know if there is a way to resize the window according to screen resolution in the runtime so that all the three frames are shown. I tried to check online if there are any solutions for this but could not find any. I tried using `window.setGeometry` and `window.setFixedSize` functions,but it did not work. The code for the window is: ``` import sys import os import threading import smtplib from PyQt4 import QtCore, QtGui, uic import sched import time form_class = uic.loadUiType("FirstTest.ui")[0] # Load the UI try: _fromUtf8 = QtCore.QString.fromUtf8 except AttributeError: _fromUtf8 = lambda s: s class MyWindowClass(QtGui.QMainWindow, form_class): def __init__(self, parent=None): QtGui.QMainWindow.__init__(self, parent) self.setupUi(self) #has some code for the field values to be shown app = QtGui.QApplication(sys.argv) myWindow = MyWindowClass(None) #myWindow.setFixedSize(500,500) myWindow.showMaximized() palette = QtGui.QPalette() palette.setColor(QtGui.QPalette.Background,QtCore.Qt.white) myWindow.setPalette(palette) myWindow.show() app.exec_() ```
