RE: [flexcoders] dynamic context menu problem
The solution I put in place for a similar problem... Add some javascript to eat the right click event (so the default menu isn't shown), and have it dispatch an event to the application. The application then dispatches a RIGHT_CLICK event having it bubble. Any UI component listening for that event captures is and prevents it from bubbling further (You want to let it get to the topmost point in the display list, and catch it on the way back down). That UI component opens up the menu you've set up for it. Gk.

The menu contains different items depending on whether various objects are selected. Ideally, I'd like to re-generate the menu options right when the user right-clicks, but I haven't found a reasonable way to do this. So instead I'm re-generating the menus every time the user (left) clicks, which is kind of expensive and is having unwanted side-effects. Unfortunately, MouseEvent.RIGHT_CLICK is AIR-only.

Re: [flexcoders] dynamic context menu problem
Thanks Gregor! This is slightly more elegant than the solution I've come up with. I *think* I follow you up to the last sentence. How do you force the UI component to display its context menu? The display() method is AIR-only... right? Is this an actual ContextMenu instance or a UI component masquerading as a ContextMenu? - Michael From: Gregor Kiddie gkid...@inpses.co.uk To: flexcoders@yahoogroups.com Sent: Friday, January 30, 2009 5:22:20 AM Subject: RE: [flexcoders] dynamic context menu problem The solution I put in place for a similar problem… Add some javascript to eat the right click event (so the default menu isn’t shown), and have it dispatch an event to the application.

RE: [flexcoders] dynamic context menu problem
I wrote a routine that all my UIComponents can link into which uses the standard Flex Menu in place of throwing up the context menu. Gk.
