Hi,
I'm using a CheckboxCellEditor within a tableViewer.
The problem is that it displays strings "true" and "false" instead of a
checkbox.
Any suggestions?
Thanks
Charlie

Hi Wayne,
I'm using a TableViewer and an ICellModifier; I don't want to implement
a custom control.
I'm posting a solution here that might help other people.
I create a CellEditor[] with instantiation of CheckboxCellEditor and
pass it to the TableViewer
I cache the TableViewer instance in the the constructor of the class
that implements ICellModifier, and toggle the field in the modify (...)
method.
Calling tableViewer.refresh() forces the LabelProvider to update a
String representation of the field in the table.

return;
DownloadableObjectInfo downloadableObjectInfo =
(DownloadableObjectInfo) object;
