Question

How can i find out if there is already a transition running on the node – for example a FadeTransition ?

Answer 1

Thank you for your help. I want to share the solution that i’ve choosen finally for my specific problem. Its the following: I wanted to fade a node on mouse click. When a lot of clicks appear, a new FadeTransition should only start when the current one is finished to prevent flickering or other phenomena.

My approach can be seen in the first line of the function:

@FXML
public void chartMouseClicked(MouseEvent event){
    if (ft.getCurrentRate()!=0.0d) return;      
    ft.play();
}

In this case, ft is a private field of the type FadeTransition which is instantiated once within an “init” function. According to the JavaFX docs, getCurrentRate() returns 0.0 when the transition is paused or stopped. I don’t need to pause the transition, so this is the way to go for me – i’m just checking the value and let my transition play again when it’s stopped.
