QPropertyAnimation how to lock button slot to avoid reset of animation

[Andre4e]

i have this code:

void myclass::on_btn_slot()
{
         QPropertyAnimation *a = new QPropertyAnimation( ui->btn , "geometry" );
         a->setStart.....
         a->setEnd....
         a->setDuration...
         a->setLoopCount....
         a->start(QAbstractAnimation::Delete....);
}

void myclass::on_btn_slot()
{
         QPropertyAnimation *a = new QPropertyAnimation( ui->btn , "geometry" );
         a->setStart.....
         a->setEnd....
         a->setDuration...
         a->setLoopCount....
         a->start(QAbstractAnimation::Delete....);
}

To copy to clipboard, switch view to plain text mode 

Once that animation is playing, how can I disable the call of the slot?
Because then if I click during animation, this resets.

I do not want to disable the button and I seek a solution that allows me
handle everything in this method / slot


i thinked to use a boolean but i should to connect the finish signal of animation with a method
