[Qt-interest] How to animate the color of a QLabel

[Malyushytsky, Alex]

Sent first version too soon, so fixed some logic below:

I have not tested it, but you can change text color using html tags:
pLabel->setText("<font color="red">Labeltext</font>")

and text is defines with Q_PROPERTY

So I don't see why you would not be able to use QPropertyAnimation.
Just change tags around text?

If you don't want to subclass QLabel, you could use a stylesheet on the label, and just use that to set a new color for each step in the animation.
