Question

How do I force the CheckboxTreeViewer class to allow for only one checked element? I could not find a style that enforces this behavior.

The only other alternative I have to so capture the check event and uncheck the other elements

Was it helpful?

Solution

SWT.SINGLE AND SWT.MULTI style bits are related to single or multiple selection in list, tree and tables.

But AFAIK you have to use addCheckStateListener and deselect all elements first and then toggle the check state of current element.
