Do you mean an animation? Check this: https://doc.qt.io/qt-5/animation.html

@jsulm
I didn't know about this class. I have widgets (FWIW, QSpinBoxes) which I want to flash for a few seconds, when their value changes, and then stop. Sometimes many of them flash simultaneously. I implemented this via my own QTimer (just one instance of that) code.

Am I missing out on anything? I like to keep the application "lightweight", so don't have any need to call QAnimation stuff.

@satyanarayana143
Why do you want example code? It would be quite a bit. I maintain a list of all widgets I wish to flash, to which I add & remove. I have a single QTimer. On elapsation I go through the list toggling the flash state, or removing items if they have flashed enough times. Flashing color is achieved by toggling the alpha state on widget->setPalette().

Oh, maybe you mean you example code of mine to give to you? Wait until @jsulm answers me. But if you are writing from scratch, unlike me, you should probably follow the link he gave you and do yours via animation instead.

@JonB Nothing wrong with your approach. But I think these animation classes can be quite handy.

I answered this previously, with an examlple for QFrame as base class here:

You should be able to adjust it for QPushButton.
