[Insight-users] fltkImageViewer and updates to surrounding controls

[Luis Ibanez]

Hi Jan,

You will have to call the

             slider->value( x )

method from the event handler that manages
the key events in this application.


The elegant way of doing this would be to use
events...


but if you are in a hurry, a slider pointer passed
to the handler will do the trick.  (just don't tell
anybody that I suggested such abomination)   :-)



    Regards,


        Luis
