问题 I have been having issues trying to move nodes in JavaFX within a 3D Scene. The issue is that I want the mouse to stay at the position within the node I've clicked, i.e., center. With a PerspectiveCamera it will alter the position.

I am wondering if this a bug that should be

问题 I am new to Java programming and opted for developing my tool UI in JavaFX8. I need to have a Spinner (new in JavaFX8u40!) for which the user can specify a integer value from 0 to 120 seconds (the easy part) but also a button which allows the user to set the spinner value directly to the given pre-set button value (here, 0).
