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 ?

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 );

Create and add an new BoundedRangeModel to the scrollbar. – camickr Aug 25 '13 at 17:34
camickr - BoundedRangeModel is an interface. How can i create the object of BoundedRangeModel and add it into scrollbar ? – Sanket Pipariya Aug 25 '13 at 17:58
Read the API and find a class that implements the interface. All models have a default implementation. – camickr Aug 25 '13 at 18:03
I found the solution by adding new scrollbars: scrollPane.setHorizontalScrollBar(new JScrollBar(JScrollBar.HORIZONTAL)); – Sanket Pipariya Aug 25 '13 at 19:11

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()).
