launching animated window from already open window

[krystosan]

I managed to animate open a window on startup, but I want to open a different window from already open window by pressing the button, in my case already open window is open in fullscreen mode with window.raise_()

Not sure but is this why the window I am trying to animate open by pressing a button is not opening

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

I am not a Python programmer but I expect that the local variable "main" in goes out of scope at the end of the function taking the table widget with it. Same for the "animation" object. Try "self.main" and "self.animation"

[krystosan]

yes, thats it. thanks. however why does the window that has button stays on top , when i have self.main.raise_() for new animating window ?

[ChrisW67]

Take a look at QWidget::activateWindow() and the notes about Windows

[krystosan]

I have got things working but animation doesn't seems to be smooth, is it because the new window is accessing the same QAbstractListModel or something else I need to add to QPropertyAnimation ?
