Hello,
I'm using QPainterPath to draw my text so I can get nice outlined text that gets displayed over video. I'm using the addText(...) function and then the QPainter::drawPath.
Some of my text I would like to have right justified instead of left justified. Is this possible? Any other suggestions?
I want it to be outlined or stroked text so it has a 1 pixel black board around the white text otherwise I would just use the QPainter::drawText(...) function.
Did you try the alignment flags?

No, what I'm saying is, from my web searching is that the only way I can get pixel stroked text is by using a QPainterPath and using addText and NOT drawText...
addText does not have the alignment flags.
oops sorry, reading to fast.
Hmm... since you are not using drawText() you probably will have to justify your self.
But that should be rather easy - you have your paths bounding rect, so all you have to do is translate to "widget right edge" - "path_bounding_rect".
Ahhh, very good idea.
I just have one more question. It doesn't seem like there is a way to clear the elements from the QPainterPath.
For example I have like 10 lines of text I would like to right justify. I would like to addText(...) get the bounding rect for that text and then translate the Painter path for each line. However there is no QPainterPath::clear() function. Does that mean I really need to construct a new QPainterPath object for each line? Seems kind of silly. What am I missing :)
Thanks
Currently from what I see in the docs you have to go the "long way".
But I don't think constructing a new path for each string is really more expensive than adding text to existing path, as addText() creates sub paths.
You think "text" but in reality this is just a bunch of paths - and you usually construct your path and draw it (fire and forget sort of), and not (re)use it like you (want to) do.
