TreeView::set_cursor() should do this. There are three versions of that
method, depending on how precise you want to be:

This should be possible, and I guess someone has achieved it. I might like
the same feature in Glom.

But do remember that this might interfer with the standard keyboard
navigation used for acccessibility.

I use the signal_key_pressed() method to detect the tab key. I have an
example app written which demonstrates this. If you'd like to see it,
I can make it available.

Do you mean set_cursor()?

Heh. Sorry my bad. I did mean set_cursor().

...and it does not work, sadly. When I specify set_cursor( Path,
Column, true ), it does not force the cell into editing mode, so I
guess I must have just discovered a bug...?
