How to use windowkeypressfcn

I have written a 5code that draws a graph. I want that each time the user clicks on escape the graph comes back to its original state. This is my code:
Figure('windowkeypressfcn',@keyP)
Function keyP(source, event)
KeyPressed=eventData.key;
If strcmp(KeyPressed,'escape')
View (3)
end
end
When I run it shows errors. It says The class "eventdata" is undefined. Perhaps java is not running

end
It's as the error says. You never defined a variable eventData. Your input is 'event'
