ScrollPane is a scrollable component used to display a large content in a limited space. It contains horizontal and vertical sroll bars.

ScrollBar Policy

You can set up display policy for scroll bar:

NEVER - Never display
ALWAYS - Always display
AS_NEEDED - Display if needed.

** ScrollBarPolicy **


// Setting a horizontal scroll bar is always display
scrollPane.setHbarPolicy(ScrollBarPolicy.ALWAYS);

// Setting vertical scroll bar is never displayed.
scrollPane.setVbarPolicy(ScrollBarPolicy.NEVER);
