How to resist Flex ListBase components scrolling on mouseWheel if html page also scrolls   1 comment

Posted at 4:42 pm in Flash/Flex

Senario:

A Flex app is part of an html page that has a scrollBar. The Mouse is over a List component and the mouseWheel is used,  browsers (PC firefox) will sometimes scroll both the html page and the List. As far as I know there isn’t any easy way to disable Flex ListBase Classes interacting with mouseWheel? I’ve seen a few posts on forums asking how to overcome this problem.

A Solution:

For anyone that wants a fix here you go (click Button under List to change options):

  1. Here’s a solution that I’ve used. It involves using JavaScript to cancel the mouse wheel event when it occurs on the Flex app:

    This way the Flex app can scroll when it has focus, and the HTML page can scroll when it has focus.
