[Insight-users] FltkImageViewer Keyboard shortcut

[Stephen R. Aylward]

Hi,

Are you still having trouble with these?   It seems like an FLTK/ASCII 
issue.   There is just one big switch statement to see if the key 
pressed matches a letter (be it an upper-case or a lower-case letter).

Could you put a cout statement in the handle method of the GLSliceViewer 
and see if a keystroke event is occuring and what letter it thinks your 
are hitting?   FLTK must handle caps on your keyboard differently - are 
you using windows or linux or ???

I'm glad you like the viewer.

Thanks,
Stephen
