The mouse wheel events are not getting eaten by the browser before they get to your swf, are they? Perhaps due to some difference in the html embed code? (I've not seen this happen, but what you describe sounds odd) I'm wondering what happens if you were to try publishing your test file as AIR, or perhaps try a different browser ? It might at least help eliminate the possibility? -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of fotis.chatzinikos Sent: 23 October 2008 12:45 To: [email protected] Subject: [flexcoders] Re: mouse wheel behaviour mxml and actionscript based components This is driving me nuts!
Go here: http://examples.adobe.com/flex3/componentexplorer/explorer.html <http://examples.adobe.com/flex3/componentexplorer/explorer.html> open visual components->general controls->Tree mouse wheel works! copy paste the code in a new flex (3) project, run the project, NO MOUSE WHEEL functionality... Any ideas? Can somebody (Mike are you there? :-) have a look at the previous post code and see if there is something wrong with my mouse_wheel handler?
