Google Maps and Adobe Flash

[iUm]

Hi,

i'm developing a standalone Flash player for Linux based on
libflashplayer.so and it's almost finished, but i've encountered an
interesting problem with Google Maps Street View drawing in windowed
mode (via XEMBED). Actually, i call NPP_SetWindow with right width and
height (i.e. the width and height of GtkWindow above which the GtkSocket
is situated) like for any other flash movie, but on Google Maps i can
see the world bihind a gray rectangle which usually serves as a border
(see http://imageshare.web.id/images/4cxzto3lqyotmloy7o.png ). That
rectangle is always 800x500 and never changes its size. But when i
change the GtkWindow's size i just can observe other parts of the world
behing the static rectangle. On a native browser that gray rectangle
changes its size accordingly to NPP_SetWindow call (i.e. size given with
that call).

What did i forget? Should i make some gtk_* command with my
GtkWindow\GtkSocket with NPP_SetWindow or there's some other secret of
proper rendering?

While i can't say what exactly is needed i recommend looking at the
plugin handlers in the chrome source if you are out guesses.
I recall seeing some workarounds related to flash drawing in there and
its mostly readable.

Regards,
Georg

Seems, there's a bug in the Adobe Flash plug-in: it depends on
arguments' order, passed to NPP_New.
E.g. to fix that problem with Google Maps i just put "scale"
argument-value pair before "salign" one in NPP_New arguments' list. So,
if "salign" comes before "scale" Street View will be displayed
incorrectly... Nothing similar with Adobe Flash ActiveX, which really
doesn't depends on arguments' order.

To Mike:
Flash plug-in can get a scriptable object from your application via
NPN_GetValue(... , NPNVWindowNPObject, ...). You should return a real
(maybe you have a javascript engine in your app), or just a virtual
(your own simple implementation) scriptable object. Then the plug-in
will call NPN_Invoke with method name "_DoFSCommand" and exactly 2
arguments of NPVariantType_String. Those arguments will be the actual
command and its argument.

I had that set up. After several hours (over a week's worth of
searching). It turns out that it's a permissions thing. Even with
allowscriptaccess set to always it wouldn't send invoke commands to a
locally started file. I had to create a dummy URL to return for
top.location. I'm sure there is another way around it, but I couldn't
find it (doesn't mean it isn't on the internet, just that I used the
wrong keywords or didn't read well enough.)

Thanks!
