Hi
Im running a program with a graphical interface in wxHaskell.
My program have one button that starts a sometimes very long computation
that even could get cyclic in some cases. I created a Stop button that when
pressed changes the State of the application (type State = Var MyRecordType
from http://wxhaskell.sourceforge.net/doc/Graphics.UI.WX.Types.html#t%3AVar
). Then my very long computation, before calling the recursive call, checks
if the State is saying to continue or stop.
In theory this seems the solution but when I tested it I find out that it
doesnt. The very long computation gets the attention of the processor and
blocks the graphical interface; clicking the Stop button dont fire the
actions.
Im not sure but is this running sequencially? Which ways have I to overcome
this block?
Best
Miguel
