I am using a Table Viewer with check boxes as following:

final TableViewer legendViewer = new TableViewer(parent, SWT.CHECK);

What is THE solution to listen to check boxes selection/unselection in this viewer ?

Thanks in advance, Manu

Take a look at class CheckboxTableViewer derived from TableViewer which simplifies the use of a TableViewer with the SWT.CHECK style.

Add an implementaion of ICheckStateListener to your CheckboxTableViewer via addCheckStateListener(). The only method you have to implement is checkStateChanged(CheckStateChangedEvent event) where event contains all necessary information about the state change.

If you need only one column you can create a CheckboxTableViewer like this:

CheckboxTableViewer myTableViewer = CheckboxTableViewer.newCheckList(parent, style);
