Hi Andrew, Effectively you can place the mouseEnter handler in the card or the stack script instead of each object script you want to document. Events in Runrev follows the object hierarchy presented in this excellent article from Richard Gaskin: http://www.fourthworld.com/embassy/articles/revolution_message_path.html -> If you want that an object display the help message, remove the mouseEnter from its script. In this case, the mouseEnter will be intercepted by the next object in the hierarchy (the group -> the card -> the bg -> the substack -> the stack, in this order) In your case, place the mouseEnter handler in your card or stack. -> If you want that a special object performs an action on mouseEnter, then displays its help message, use the pass command in your control, like this: on mouseEnter doSomethingWithTheCtrl pass mouseEnter -- pass the mouseEnter to the next object in the hierarchy end mouseEnter -> If you want that your mouseEnter handler follows all the hierarchy place a mouseEnter event in each level of the hierarchy, with the pass mouseEnter command. -> You can also pass the handler directly to an object without follow the hierarchy. For this, use the send, dispatch or call commands (this commands was recently discussed in this thread http://www.mail-archive.com/[email protected]/msg131598.html), like this: on mouseEnter send "mouseEnter" to anotherObject end mouseEnter -> At last you can stop the event with the exit command: on mouseEnter if (the helpText of the target is empty) then exit mouseEnter displayHelpMessage the helpText of the target pass mouseEnter end mouseEnter HTH, -- -Zryip TheSlug- wish you the best! 8) http://www.aslugontheroad.co.cc _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
