Difference between JScrollPane.getViewportBorderBounds() and JScrollPane.getViewport()

What is the difference between 

JScrollPane.getViewportBorderBounds()

and 

JScrollPane.getViewport()

and 

JscrollPane.getVisibleRect()

First two are returning same dimension.

Solution

  • getViewportBorderBounds() returns Rectangle which represents the bounds of the viewport border

    getViewport() returns current JViewport.

    getVisibleRect() returns visible rectangle of the JScrollPane (including borders and scroll bars), which is inherited from JComponent.

    I don't see any comparability among these three methods. They are telling you different things. Read for more details on http://docs.oracle.com/javase/7/docs/api/javax/swing/JScrollPane.html
