There is a difference between the row size of a fresh created table and the one after applying resizeRowsToContents () so I guess resizeRowsToContents is not used as default. But you are right, there is still too much wasted space. I therefore pushed your patch with cset .
Thanks for the patch.

Using resizeRowToContents() is about 20% less height than pre-changeset, but it still has pretty much whitespace. (One would think that resizeRowToContents() is what is being used by default. I guess not.)

If that amount of whitespace is alright with others, it's fine by me. But a little less would be nice. [I also think that a little too much space is taken up by the editor menu items and icons. Maybe that isn't the case for a monitor bigger than I have or of higher resolution.]

The spacing within resizeRowToContents can be changed via the delegate size hint:

But that would require creating a class that inherits the QTableView. Not a difficult thing to do. Probably the proper thing to do. But ultimately the row height scaling is tied to font height somehow.

Should we look a little further at what the code (link below) is doing?

It looks to me that every column in the row is checked for the height it requires and then I assume the row is chosen as the maximum. To get the required size, the QItemDelegate is inquired for the given index. I'm guessing that an item delegate is something that specifies the height of an object without having to render that object.

So, maybe we'd have to go back to the items within the table and change their delegate somehow.

I slighty modified the patch. Using resizeRowToContents (), we do not have to take care of font metrics. What do you think?

Try the new changeset. Kind of scrunched together, but I don't mind it. Can add 10% if users complain.

Probably is. I garnered that is what you were aiming for with the resize feature. But that resize feature must be set up to have a lot of margin. I'll search around in the Qt documentation if there is some way of adjusting that. As a last resort there is probably a font model which will provide the height of an 'h' or something.

Is there some way to make the height dependent on the font size?

This patch will adjust the appearance of any new rows in the workspace view after a change in the workspace data model.
