import sys
class Web_Browser(QtGui.QDialog):
def __init__(self,parent=None):
QtGui.QWidget.__init__(self)
self.resize(550,400)
open=QtGui.QPushButton('OPEN')
self.connect(open,QtCore.SIGNAL('clicked()'),self.ok)
grid=QtGui.QGridLayout()
grid.addWidget(open,1,0,1,1)
self.setLayout(grid)
self.setWindowTitle('main windows')
def ok(self):
web=Web_Browser()
web.setModal(False)
web.setWindowTitle('sub window')
web.exec_()
app=QtGui.QApplication(sys.argv)
app.setFont(QtGui.QFont("Helvetica", 16))
main=Web_Browser()
main.show()
sys.exit(app.exec_())
