560964 - Mousewheel problems when an embedded swf wmode is set to opaque or transparent

Status: RESOLVED DUPLICATE of bug 376679

(Core Graveyard :: Plug-ins, defect)

Description

[Dave]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3

If you embed a SWF in an html page (method seems unimportant) and set the wmode property to "opaque" or "transparent" Flash does not receive MouseWheel events.  

Behaves as expected in IE6,7,8.

Reproducible: Always

Steps to Reproduce:
1. Create a new HTML page
2. Embed a swf in the page
3. set the wmode parameter to opaque or transparent
4. Load page, use mousewheel over a region where behaviour is expected
Actual Results:  
Flash does not receive MouseWheel events, eliminating any potential scrolling/zooming/etc...

Expected Results:  
Flash should receieve MouseWheel events exactly the same as if it were in wmode=window (for example).

Workaround: Have javascript listen for the Mousewheel event and then have Flex/Flash listen for a callback from the External Interface and then redispatch the MouseEvent.

Currently, we don't send native mouse wheel messages to plug-ins, it's going to be fixed by bug 483136. However, Flash Player doesn't handle the messages probably.

Dave, would you attach a simple testcase to this bug?

One is a swf which reactions to mouse wheel event simply (I hope counting up/down the delta value of the events). When you attach the swf to this bug, the URI is fixed. So, you can write a HTML file which uses the swf by the URI. Then, we can load the testcase without downloading.

Does it still exist with Firefox 11+ and Flash Player 11.2.202.233+ ?

Hi,

I have tested this issue on the latest Firefox (44.0.1) release and the latest Nightly (47.0a1) build and I could not reproduce it. I have opened the provided test case and I was able to scroll and zoom in "wmode". It seams that the issue was probably fixed along the way.

Firefox: 44.0.1, Build ID: 20160205155049
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0
Firefox: 47.0a1, Build ID: 20160210071115
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0

Considering that Firefox changed a lot from v3.6.3. and also the flash plugin received numerous updates, I will mark this issue as Resolved - WFM. Reporter, please feel free to reopen it if you are still having this issue. 

Thanks,
Cosmin.

Thank you for your test. This was a dup of bug 376679 which was fixed in 44.
