[PyQt] Call a window from other parent window

[Sergio Jovani Guzmán]

Hi all!

I am learning PyQt and I have a question.

I have two classes, one for each widget:

==================
class Main(QMainWindow):
	def __init__(self):
		QMainWindow.__init__(self)
		loadUi("frmmain.ui", self)
				
class Conectar(QDialog):
	
	def __init__(self):
		QDialog.__init__(self)
		loadUi("frmconectar.ui", self)
=====================

My question is, how can I call and show a widget from other with parent?

For example, open Conectar() window from Main() window?

Many thanks!
