Non editable ListGridField that not starts editor

[thiebal]

Hi,

I have a ListGrid with editable rows (edit by row, not by cell). The editor is started by a single click.
One of my field (non editable) is an icon field used to show a window. But when this field is clicked, it shows the window AND it starts the editor...
Is there a way to not start the editor from a specific field.

Thanks

Cedric
