Adding to TTV rewrite umbrella. Unfortunately, we won't get a new TTV for 4.0 - but soon
after (we'll get a new output window and GTK support instead in 4.0).
BTW, this is filed as a P2 defect, but it's unclear to me what *should* be used for the title
of the first column, if not the root node's display name.
Closing as INVALID since as far as I know this is as designed; if you'd like to follow up and
suggest what should be used instead of the root node's display name, feel free to reopen.
there must be a method setColumnTitle or something similar to set the
title for the first column
Okay. I see no such property on TreeTableView, so will treat this as an enhancement
request. Out of curiosity, what is the problem with simply setting the root node's display
name to whatever you want?
