I have a NSOutlineView which I want to make several columns hidden in response to a user action. I have set up the outlineColumn to resize with table and the rest have fixed size, so that when one or more columns are hidden, the outlineColumn widens accordingly. In normal conditions everything goes as expected.

However, if the user is editing a row of the outlineColumn and then decides to hide a different column, the focus ring of the resized outlineColumn is not changed and the result is a mess of several columns in that row.

I just need a way to tell the outlineView that update the size of the cell being edited (and its focus ring), or simply a way to programatically commit and accept the user changes on the cell. I can not use commitEditing because the outlineView is not bound to any controller, and I use the data source methods instead.

Any help will be appreciated
