Text wrapping depends on the OS/DE, AFAIK. There was an issue on Qt-

nicely with your strings)
If you want to force a line break, \n comes in handy. But I suggest to
not mess with the OS/DE algorithms.
At least for Windows and the gen VCL plugin on Linux, this uses the
LO-internal logic in HelpTextWindow::SetHelpText.
From what I can see, the help text for the Sort dialog case Regina
mentions has 146 characters, while HELPTEXTMAXLEN used in there is
currently 150, i.e. the current implementation considers that "short
enough" to fit into one line.
If that's considered too long, that would probably be the place to
adjust, e.g. it wraps when I set HELPTEXTMAXLEN to 140 locally for a
quick test with the gen VCL plugin.
I confirm, that a smaller HELPTEXTMAXLEN will introduce a line break.
But that is done by using the else case (HelpWinStyle::Ballon). And that
introduces a timer. And the timer is so, that the text disappears before
you can read it completely. The HelpWinStyle::Quick case repeats the
tooltip rendering until the mouse leaves the text. so that is time
enough to read it.
I had hoped, that there was a setting in gtk+ itself for forcing wrap of
the text.
Kind regards,
Regina
