[vtkusers] Adding a text widget into qvtk

[Rodrigo Lovera]

Hello all,

I was wondering if any of you know of a way to idk add a button at a gui
developed with qt that allows me adding a text widget in which I could
write on an image at a position of my selection. I don't mean a presaved
text but a text I'd like to write at the moment of the display. Any idea 'd
be useful.

Other thing, does anyone know of a way for calculate the area of a region.
I mean I got a volume or an image but I want to calculate the value of the
area of some specific region, maybe a region delimited by vtkcontourwidget,
any Idea for that 'd be much appreciated.

Thx in advance
