Close window ( Doubt )

Hi Guys!

I'm hours trying to solve this code .... how do I close the first by window the X title bar button...popup and close together?

Obs: (I'm using PyQt4)

Code:

---

#!/usr/bin/env python
#-*- coding: utf-8 -*-
 
import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
 
 
class Mainw(object):
	def __init__(self, MainWindow):
		super(Mainw, self).__init__()
 
		self.cw = QWidget(MainWindow)
 
		self.btn1 = QPushButton("Popup", self.cw)
		MainWindow.setCentralWidget(self.cw)
 
		self.btn1.setGeometry(QRect(0, 0, 100, 30))
 
 
		QObject.connect(self.btn1, SIGNAL("clicked()"), self.openpopup)
 
	def openpopup(self):
		self.pop = QWidget()
		self.pop.setGeometry(QRect(100, 100, 400, 200))
		self.pop.show()
 
 
 
if __name__ == "__main__":
	app = QApplication(sys.argv)
	MainWindow = QMainWindow()
	main = Mainw(MainWindow)
	MainWindow.show()
	sys.exit(app.exec_())

Reimplement the main window closeEvent() and close it explicitly.... at least you could if your code was taking a traditional approach to subclassing QMainWindow.

Solved.

The function closeEvent() is inappropriate for this case.
I just created a kinship between the windows to make this possible. The closeEvent () now comes as a complement.

class popup(QMainWindow):
	def __init__(self,parent=None): # Parentesco
		super(popup,self).__init__(parent)
 
 
		self.setWindowTitle("Janela Popup")
 
 
		self.setMinimumSize(400 , 400)
 
 
 
class Mainw(QMainWindow):
	def __init__(self, parent=None):
		super(Mainw, self).__init__(parent)
 
 
		self.setMinimumSize(400 , 400)
 
 
		self.setWindowTitle("Janela Principal")
 
		self.btn1 = QPushButton("Popup", self)
 
		self.btn1.setGeometry(QRect(100, 50, 200, 200))
 
		QObject.connect(self.btn1, SIGNAL("clicked()"), self.openpopup)
 
	def openpopup(self):
		pop = popup(self)
		pop.show()
 
 
 
if __name__ == "__main__":
	app = QApplication(sys.argv)
	main = Mainw()
	main.show()
	sys.exit(app.exec_())
