overlay xul elements over mozilla plugin

[luca]

Hello all. I'm working on a media player application. The GUI is written in XUL with JavaScript. At the moment I'm developing it as a Firefox extension on windows, although the eventual goal is to run it as a multi-platform XULRunner application.

I'd like to display XUL boxes on top of the VLC plugin element (to create an OSD with controls). I thought I'd be able to do so with a <stack> element, so I tried

Code: Select all

<stack id="player_stack" > <html:embed type="application/x-vlc-plugin" pluginspage="http://www.videolan.org" version="VideoLAN.VLCPlugin.2" width="640" height="480" id="vlc"/> <hbox id="menu" pack="center"> <vbox pack="center"> <description>top</description> </vbox> </hbox> </stack>

However, the VLC plugin covers the menu, even though the stack should place it below. I've tried the same code but replacing the html:embed with a normal XUL box and the stack worked as expected.

Any ideas about how I could get the XUL elements to display on top of the VLC plugin? (or why it's impossible, if that's the case)

Thanks in advance.

this is unfortunately a limitation of the mozilla plugin architecture (especially on windows).
