How to stop an animation when a new one starts c++

MEsc

Hello, I have a problem. I have a progressbar connected with timeline animation. Always when I press enter the timeline should restart, but instead the old animation is running until its finished. And the new animation, which was created when i pressed enter is also running from start. I want that everytime I press enter the timeline starts new and the old one should stop. Is that possible? I try to solve this for days...

@MEsc Why do you create new animation every time you press enter? Just reuse the existing animation: stop it if it is running (https://doc.qt.io/qt-5/qabstractanimation.html#stop) and start it again (https://doc.qt.io/qt-5/qabstractanimation.html#start).

@jsulm that was an shortened version of my problem I have also a QLineEdit and I only want to stop the animation when QLineEdit is not empty.

Then do so, what is the problem?

@jsulm when I press enter the function stops either if the QLineEdit is empty or not. It should first check if QLineEdit is empty and if not then stop the animation(here: QTimeLine).

So change the order - I mean you're the programmer who programmed it so first checking for the QLineEdit and then doing something other shouldn't be that hard to add.
