synchronize scrolling of N number of jtables in java swing

Question

I have a requirement of having N number of tables arranged in a grid pane side by side provided height of the scrollpanes of all the jtables remains same. Now i want to synchronize scroll of all the jtables means if i scroll the first jtable then rest of the jtables should scroll automatically by the same amount.

Anyone has any idea about this ?

Answer 1

Try sharing the model of the scrollbar. Something like:

JScrollPane scrollPane1 = new JScrollPane(...);
JScrollPane scrollPane2 = new JScrollPane(...);
BoundedRangeModel model scrollPane1.getVerticalScrollBar().getModel();
scrollPane2.getVerticalScrollBar().setModel( model );

Answer 2

Get the scrollbars of your scrollpanes (getHorizontalScrollBar() or getVerticalScrollBar()). Then catch events from these. When an event occurs, modify the viewports (getViewport()) associated to the scrollpanes with setViewPosition() (from getViewPosition()).
