I am looking for a solution to add node\'s with fade-in or flipping or any animation. Thanks for any help.
I found the same question but without any further help here: A
You can use the built-in Transitions or a 3rd party library such as FXExperience Canned Animations.
For an example of integrating an animation with a standard layout pane see this LayoutAnimator code used in the example solution to: Animation upon layout changes. The LayoutAnimator is very generic and will work with other Panes than the FlowPane sample it is provided with (it just looks a bit cooler with the FlowPane).
