Flex mouse wheel event not triggered on VBox?

Your problem--you may have guessed- is that the MouseEvents aren't firing. I suspect is the same issue with that exists with FocusEvents. Containers do not dispatch these events on their own; they only get events bubbled up from their children; which do accept mouse and focus events As one workaround, you may try adding a transparent Image as the first child to your component.

The background will still show through, but the image should pick up the relevant events and bubble them up to the container.

– takteek May 24 at 21:47 @takteek I think you mean; can a container be modified to dispatch MouseEvents. My suspicion is yes; but I don't know what that would entail. You'd have to pop open the framework code and see what you can figure out.

– URL1 May 24 at 22:14 I looked at the Container source code for a while but didn't get anywhere. It's frustrating when I can't figure out how something is working in flex but at this point I don't think it's worth the effort. I ended up using setStyle("backgroundColor", 0xFFFFFF); to force it to create a background which then allowed scrolling to work.

Thanks. – takteek May 24 at 23:01.

Year ago we had similar problem, that mouse wheel scroll did not work on TabNavigator. Found workaround here: https://bugs.adobe. Com/jira/browse/FP-289 and https://bugzilla.mozilla.Org/show_bug.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
