What is the difference between
JScrollPane.getViewportBorderBounds()and
JScrollPane.getViewport()and
JscrollPane.getVisibleRect()
First two are returning same dimension.
getViewportBorderBounds()returns Rectangle which represents the bounds of the viewport bordergetViewport()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
