fade in and out of bunch of label inside QVBoxLayout with animation

[saeid0034]

Hi, I have a QVBoxLayout that I have a bunch of label inside it
I need to be able to fade in and out all of the label inside it in same time with an animation
so I wonder how can I get all of the labels inside a QVBoxLayout and fade in or out them?
thanks in advance.

Make a new widget, put your VBoxLayout with your labels inside and fade-out or fade-in the whole widget using QGraphicsOpacityEffect and QPropertyAnimation.

@Pl45m4 no I can't do this, because there is other things inside layout that I don't want to fade
I want only labels

See qFindChildren(). Or put all pointers to your desired labels in a container when you create them.
