For any descendants:
See my answer to peter, there's no such thing as a 'table API' in Qt's itemviews. There's only a generic model API and thats what all views from Qt itself rely upon. > BTW, this model reveals another issue: the focus can be set to all table > items by clicking with the mouse, but only to the left column items by > keyboard. Is that to be expected? Given, above is enough to implement a > read only table, shouldn't it handle keyboard navigation properly, too? Do you mean the focus rectangle (on linux this is a small dotted line around the current item) or the normal selection? Both things are not dependent upon the actual model, only the view.
