ScalarBarActorQuestion in vtk23

[Gala'Vi and Liss @ Mainframe Country]

The scalarbaractor turns black and the range goes from 0 to 1 also if you
render with a texture. Which is really annoying, because I'm doing texture
thresholding and the bar comes up black. If you resize the window however,
it comes up normal and stays normal.

I would suggest trying to resize the window and if that doesn't help,
issue another renWin->Render() call. This makes the bar update itself and
then it works. So where you say renWin->Render(), just duplicate that
line. I can't use that method myself, because I'm using FLTK to handle my
interfaces, but if you use TCL/TK you should be able to get away with
that. I'm really beginning to hate that scalar bar though.

Good luck.
