Threading issue in swing GUI with type()

Asked by Liam WHite

My code runs fine when executing just this method

http://pastebin.com/XPhZc0Zc

but when I try and call it from within a gui it falls over on s.type(...)

Any help would be appreciated!

Sikuli's keyboard and mouse actions are internally implemented using java.awt.Robot and the used functions per definition cannot be run in code, that is dispatched from the Java Swing GUI dispatcher (EDT).

... which means it cannot be used in any methods that are added to GUI elements as event listeners.

The only solution is to delegate the call of the stuff containing the above Sikuli features to your own listener thread, that is triggered using notify() from the GUI element action function.
