Re: [Fxruby-users] FXMenuCommands as options

[Sander J. <sa...@kn...>]

Although they don't use datatargets its a similar concept. The MenuCommand 
sends a SEL_UPDATE to its target, in this case the table and the table 
responds by sending a message back to the sender (the menucommand) to either 
check or uncheck himself.
