launching animated window from already open window

[krystosan]

What are the values of sw and sh at lines 17 and 18? What screen is an unshown widget on?

Looking at that I updated my code but still it seems doesn't work, I just see a flickr

from PyQt4 import QtCore,QtGui
from functools import partial
import sys
 
class MyTableView(QtGui.QTableView):
	"""docstring for MyTableView"""
	def __init__(self, parent=None):
		super(MyTableView, self).__init__(parent)
		self.showFullScreen()
		sw = QtGui.QDesktopWidget().screenGeometry(self).width()
		sh = QtGui.QDesktopWidget().screenGeometry(self).height()
		self.setGeometry(QtCore.QRect(0, -(sh), sw, sh))
 
class WindLauncher(QtGui.QMainWindow):
	"""	docstring for WindLauncher
	"""
	def __init__(self):
		super(WindLauncher, self).__init__()
		self.btn = QtGui.QPushButton("Launch")
		sw = QtGui.QDesktopWidget().screenGeometry(self).width()
		sh = QtGui.QDesktopWidget().screenGeometry(self).height()
		callLaunch = partial(self.launchWin, sw, sh)
		self.btn.clicked.connect(callLaunch)
		self.setCentralWidget(self.btn)
 
	def launchWin(self, sw, sh):
		main = MyTableView()
		animation = QtCore.QPropertyAnimation(main, "geometry")
		animation.setDuration(500);
		animation.setStartValue(QtCore.QRect(0, -(sh), sw, sh));
		animation.setEndValue(QtCore.QRect(0, 0, sw, sh));
		animation.start();
		main.show()
		main.raise_()
 
if __name__ == "__main__":
	application = QtGui.QApplication(sys.argv)
	main = WindLauncher()
	main.show()
	main.raise_()
	sys.exit(application.exec_())
