multithreading - JavaFX-8: Can I read (not write) scene graph properties from background thread? -

-

i'd write background thread automatically saves position of window preferences after waiting 1 second. understand cannot manipulate scene graph background , need call platform.runlater(), accessing property unsafe? i.e. call mywindow.xproperty.get() or mywindow.getx(). have inside platform.runlater()?

thanks
