Description

16 years ago
Procedure: View <http://www.gadgetscope.com/tests/trans.html>.

Expected: "Trans" is floating over background image, no white box is present.

Actual: "Trans" is drawn over a box of the animation's background color.

This might be a limitation within Macromedia's Netscape plug-in, but it's
probably a good idea for a bug on this to exist anyway, to find out whether the
browser is able to handle effects like this.

Build: 2001080508 Win98
Macromedia Flash MX is about to be released, I think that MM guys should correct
this in the new version of his plugin. 
Testing the testcase with the Flash Player 6 Beta the problem still occurs.
Anyone know some MM people email to include on the CC?

The URL to download the Flash6 beta player is:
http://www.macromedia.com/shockwave/download/beta/flashplayer6/
and the feedback form to bug report about this beta player is:
http://www.macromedia.com/bin/fp6betafeedback.cgi

I've already reported a bug about this in their form, but if more people report
this bug maybe Macromedia make something about this old and annoing issue.
Adding Arun and Marcio to CC, they may have other ways to help us with it.

Ok, in a a discussion on a Macromedia newsgroup, I've been informed from MM
people that it has nothing to do with the Flash plugin, they say the browser
that must support wmode.
Anyone knows if there's a specific bug for this wmode problem, I know the bug
99974 and bug 64090 but they were marked INVALID... should we reopen those bugs?

BTW, the people that told me that this problem has nothing to do with the player
was Petter Hall
(http://www.macromedia.com/support/forums/team_macromedia/team_flash.html) and
Clint Critchlow (Macromedia Technical Support)
No longer blocks: 64090, 99974

Flash does not support wmode in 4.x either. The ball is currently in
Macromedia's court to implement this. If there are bugs in Mozilla, we can fix
them if we know what they are.

Mozilla now supports the windowless API for plugins. In this mode, plugins are
not confined to a widget and can render anywhere on the page. During
compositing, the plugin gets a device context from us to render into. We've been
working with Viewpoint (http://www.viewpoint.com/) on their windowless plugin
and it has features similar to Flash's wmode plus is scriptable. It may be a
possible workaround.

One interesting thing is that the Macromedia people hasn't bothered filing a bug
if they don't manage to get a wmode implementation working. Couldn't someone
(Fabricio?) who has been in contact with them ask them to do so, or ask them to
comment in this bug. Mozilla and plugin authors obviously need to work together
to get things going, it can't be fixed on one side only.
Hi Jonas, I've asked for it in both Macromedia newsgroup and in the Flashcoders
mailing list. Below is the feedback by Branden Hall and Clint Critchlow:

Branden Hall:
"It actually has nothing to do with MM until Mozilla settles on a plugin
format. The netscape plugin format is old and quite funky and it doesn't
support windowless plugins very easily. Until the Mozilla project settles on
a new format there's nothing that MM can do about it.

-Branden"

Clint Critchlow:
"I already posted my comment on this problem with the Netscape browsers.  You
can see it at <http://bugzilla.mozilla.org/show_bug.cgi?id=93959>.

You can make feature requests at,
<http://www.macromedia.com/support/email/wishform/?6213=9>"

simple sample showing how to create a plugin for Gecko with transparency and z-index (sample.zip)

Okay, after spending the day with chrisd working on this problem, I have
created a simplified testcase showing an example of how easy it is to use both
transparency and z-index layering in Gecko as long as the plugin supports it.
It contains the Win32 source of the windowless sample from the mozilla tree,
the compiled binary (npwinless.dll) and a testcase using absolute positioning.
Notice in the testcase the plugin can be layered underneath even a transparent
DIV like you would create menus with.

Perhaps someone from Macromedia would like to look at this sample?

Since Mozilla already theoretically supports everything Macromedia will need to
make their Flash plugin support windowless mode with Mozilla, this is an
evangelism issue.

Is it really? The Platform and OS for this bug are both set to All, but isn't
this only working under Windows?

Comment 17

15 years ago
See bug 137189 for the RFE for winless support on Linux. 

This bug is set to ALL but implies just platforms that it's possible. Since Mac
does not use native widgets at all, it's possible to have a
winless/transparent-effect on Mac platforms.

Well, doesn't Flash only support windowless mode on Windows anyway? In that case
adding support for it to other OS's ought to be put in another bug.

Yes it is true that "wmode" (windowless mode) support is still not there in the
Flash plugin available for Netscape and Mozilla browsers (Win32/OSX in
particular).  I'm working with MM to see that this happens.  Here's peterl's
brain dump on what the plugin ought to do via ye olde 4.x Netscape Plugin API :-) :

"You can refer to the 4.x API doc, specially this section:
http://developer.netscape.com/docs/manuals/communicator/plugin/draw.htm#1005641

You can also check out a simple Win32 sample windowless plugin I attached in bug
93959.

Basically, windowless plugins on Windows are similar to regular plugins on Mac
in that the browser provides the plugin with a drawing surface (hdc/port) to
render into and passes all events (as opposed to getting them from the OS). By
setting setting some flags through the NPAPI, you can make the plugin area
opaque and by using CSS z-index, you can control what order the plugin is asked
to paint. Let me know if you have any questions."

From the Flash 6 beta release notes
(http://www.macromedia.com/software/flashplayer/special/beta/release_notes/):

What's New in this Version
  Windowless Mode now implemented for Netscape Windows & Mac OS X
     Windowless mode allows you to take advantage of the transparent movie,
     absolute positioning, and layering capabilities available in the browser
   . Windowless mode is controlled with the wmode parameter in the object tag.

     The following browsers are supported:
        Windows Netscape 7.0
        Windows AOL
        Windows Mozilla 1.0
        Windows CompuServe
        Mac OS X Netscape 7.0
        Mac OS X AOL
        Mac OS X Mozilla 1.0
        Mac OS X CompuServe

Which would be all stable Windows/OSX gecko based browsers, to my knowledge...

Now all we need is Linux support.  ;)

Simple testcase reusing the macromedia sample: 

http://taboca.com/worlds/gek/testcases/wmode/wmode-macromedia.html

At Macromedia documentation, the link
(http://www.macromedia.com/support/flash/ts/documents/wmode.htm) that is located
from the release notes document is not updated corretly with the wmode attribute
for the EMBED element (EVANGELISM ISSUE :) The above URL is the version with the
EMBED element and wmode="transparent" attribute. Just works!!! :) Tested with W2K ;)
there are some focus issues in that testcase, I can't seem to press the play button.

Comment 30

Implementation of Windowless mode on Linux appears to be blocked by 137189.  I 
have the framework in place, it seems to work, but I can't complete it unless I 
have the hooks to copy the pixels from the browser window into our offscreen 
buffer at the start of our refresh cycle.  After a little thought this would 
pretty much require Mozilla to render to an offscreen XImage and ping Flash 
when the browser has rendered its image so we can pickup the buffer and do our 
render pass. 
 
Alternately the browser needs to query the plugin so we give you our XImage, 
you render in to it and return it when done so we can do our render pass and 
then either the browser or the plugin copies it to the display.

If this is going to make it in to the Flash 6 Linux player there will beed to 
be a working API to get an off screen image of the browser window by November 
4th.  Once an API is roughed out I will supply a player that is using it for 
testing. 
A new beta just went out, and on windows, wmode/events seem to be fixed

Comment 33

I'm afraid the window is closing to get wmode in the Flash 6 Linux player.  I'm still waiting for the hooks in Mozilla to implement this in X11.

a better test case is available at:
http://www.macromedia.com/support/flash/ts/documents/wmode.htm

where it can be seen that "Flash 6.0r61" which is the latest beta doesn't
support WMODE in latest nightly build 20021202 on WindowsXP

Comment 41

15 years ago
It doesn't look like a good example to me as wmode="transparent" isn't set for
the embed tag. So, it won't be windowless.
new flash has been released with wmode for windows, testing linux right now!

Comment 43

15 years ago
http://www.teledanmark.dk/html/forsider/forsiden.html is a good example.
using "Shockwave Flash 6.0 r65" I cant click any of the links since the flash
plugin seems to take over.

The flash on the site is written in:
http://www.teledanmark.dk/js/flashWrite.js
which has "wmode=transparent" on the embed tag.

Comment 44

Henrik - the problem you are referring to is covered by bug 182299 as you know.
This bug is about evangelising Macromedia to support windowless mode. With the
latest release of Flash they have done that. It is debatable how the problem in
bug 182299 should be fixed, but it is probably a Mozilla problem not a Flash
problem.

Doron - You don't need to test the Unix version, it won't work. Windowless mode
is not supported under Unix by Mozilla. See bug 137189.
I mean macosx :)

Comment 46

I would like to point out one behavior with Z-inde, I belive is a bug, please
input. I found this case in one of the many wmode bugs on the Tech evangelism
court. I simplified the testecase and it's online: 

http://taboca.com/worlds/gek/testcases/wmode/wmode-globo.html

What happens: 

1) Table elelement with FLash using wmode. 
2) After the table, DIV element with the GLOBE icon (GIF) and position:absolute;

Expected behavior: the globe icon appearing on top of the flash. Note that if
you embed the table+flash inside a DIV with position:absolute, then it works as
expected.

I have a question regarding this flash issue.

Do I understand it correctly, in that flash images/movies should always appear
above other page contents (such as an asbsolute div tag) UNLESS, the
wmode="transparent" attribute is added?
correct, flash movies without the wmode="transparent" will be above everything,
IE have the highest z-index.

What should the behaviour be when the plugin is not installed?

If I visit some of these test pages with Konqueror 3.1 (no Flash plugin) on Red
Hat 9, ie:

http://www.gadgetscope.com/tests/trans.html
http://taboca.com/worlds/gek/testcases/wmode/wmode-globo.html

...the blank area occupied by the embedded object *is* transparent.

Viewing these same sites using Firefox (also without the Flash plugin) shows a
blank rectangle containing the plugin icon, obscuring the background.
