java - JavaFX: How to set you scrollbars of a ScrollPane in the center? -

i have class extends scrollpane. have put pane of 4000 x 4000 (h x w) in scrollpane. , want scrollbars centered in center, on 2000 x 2000. if run gui, see whatever have placed on 2000 x 2000 possible?

thanks in advance!

you can set scrollpositions with:

scrollpane.setvvalue(2000); scrollpane.sethvalue(2000); 

look here: https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/scrollpane.html#setvvalue-double-

you can calculate actual position, want scroll to, of viewport bounds:

bounds bounds = scrollpane.getviewportbounds(); scrollpane.sethvalue(2000 - bounds.getwidth()/2); scrollpane.setvvalue(2000 - bounds.getheight()/2);
