Pyqt How To Get A Widget's Dimensions

I am currently developing an application in which i cannot use modal windows (due to some application constraints). However, in some cases i would like to simulate a popup window.

Solution 1:

For getting Qt Widget size:

import sys
from PyQt4 import QtGui, QtCore

app = QtGui.QApplication(sys.argv)

mainWindow = QtGui.QWidget()
width = mainWindow.frameGeometry().width()
height = mainWindow.frameGeometry().height()

Solution 2:

For gettting screen size

import sys
from PyQt4 import QtGui, QtCore

app = QtGui.QApplication(sys.argv)

mainWindow = QtGui.QWidget()
screenShape = QtGui.QDesktopWidget().screenGeometry()
mainWindow.resize(self.screenShape.width(), self.screenShape.height())
mainWindow.show()

Solution 3:

You can use frameGeometry or geometry depending on your needs.
