[vtkusers] vtkBalloonWidget-like class

[John Norris]

Hi,

I've created a class based on vtkBallonWidget, but instead of strings 
based on which prop the cursor is over, it builds and displays a string 
based on field data from the dataset and cell its hovering over.  This 
works fine, except that sometimes the balloon pops up when it shouldn't, 
i.e. when the cursor is not over prop.  This even happens when the 
cursor leaves the VTK window entirely.  It only behaves this way about 
half the time, though, and performs the way I expect the rest of the time.

Has anyone experienced similar behavior with vtkBalloonWidget?

I'm using the latest VTK from CVS.  I'm compiling on an XP box with 
Visual Studio 8.

Thanks,
John
