Auto Scrolling QListWidgetItem

[ChrisW67]

The problem I see is that when you are not editing the cell in the QTableView there is no widget that you can do this with. When you are editing the cell you want a standard QLineEdit rather than trying to edit a bouncing message

You could render the text with a (sometimes) variable offset in the delegate paint() routine, but the delegate paint routine would only be called when it is required to repaint a particular cell (value changes or scrolls into view). The trick would be how to get this to fire periodically without forcing the redraw (update() or repaint()) of the whole QTableView. Not obvious to me.

Ah, yes, very true. With my solution it would be like editing karaoke. And you certainly wouldn't want every cell to be continuously scrolling back and forth, only the selected one.

Never mind - anything that I can envision would be hideous.

It's not a big deal. One calls update() on the view's viewport using QAbstractItemView::visualRect(). Provided one uses Qt4 despite that his profile says otherwise (yeah, I know there is no QListWidgetItem in Qt3).

The epilepsy-warning issue still remains, though. I can't even think what it would look like if the text was spinning in multiple cells at once.

Ahh, you live and you learn.
