![]() ![]() Doing that would allow you to open several popups. The equivalent in the example could be changing to self.w = in constructor and then doing self.w.append(MyPopup(.)). This also means that if you need to create several popups you have for example to put them in a python list and you should remove them from this list once the popups are closed by the user. This can be seen clearly because if you press again the button you'll see that as the second popup appears the first one is closed. The reason is that when the local variable w goes out of scope as no one is explicitly referencing the widget the widget gets deleted. ![]() ![]() by using w = MyPopup(.) instead of self.w = MyPopup(.) the window apparently doesn't appear (actually it's created and it's immediately destroyed). This software is part of the Qt framework, the platform independent GUI framework that is also used to run itom itself. What I think can be surprising for Python users and may be is the problem you are facing is the fact that if you don't store a reference to the new widget in the main e.g. The Qt Designer is used to create a custom user interface, that can be displayed within itom and interact with itom and Python code. nnect(self, SIGNAL("lastWindowClosed()"), ebye ) In this tutorial, were going to cover how to create a pop up window for messages like warnings to the user in PyQT. nnect(self.btn1, SIGNAL("clicked()"), self.doit) Self.btn1 = QPushButton("Click me", self.cw) The following is a simple program that creates a main window with a button where pressing the button opens a popup #!/usr/bin/env python A common error that can drive you crazy is forgetting to store the handle of the popup window you create in some python variable that will remain alive (e.g. ![]()
