[Bug 115798] Re: Firefox menus don't hold the "Menu" window class

[LordFarquaad]

I made a little mistake: it's the "window type" and not the "window
class" that is incorrect.

I don't know how to check this outside beryl...  I suppose this is a
property that might affect the behaviour of the window manager (but not
necessarily) and I don't know how Metacity is affected by it...

I don't know exactly how the "window class" property works (I suppose
the software chooses it so it is independent of beryl, isn't it ?) and
how to retrieve it without the beryl settings manager. With that tool,
go in "window management", "Set Window Attribs by various criteria" then
choose "Window Opacity", click on the [+] button, select  "Window Type"
in the select box, type "DropDownMenu" in the text field and choose some
value for the opacity. Do the same for "Menu" and "PopupMenu" window
types. Now open some Gnome software (gnome-terminal for example) and
open a menu (for example the "File" menu or the right-click one): it's
transparent. You can also check that the "Applications" menu in the
gnome-panel is also transparent, as any other menu in the system
(including those in Windows softwares running under Wine I think !). But
Firefox's menus are not ! Now if you set some transparency for "Unknown"
window type (in Beryl Settings Manager), Firefox's menus will become
transparent too...

For the screenshot you ask, I don't know how to open 2 menus at the same
time so that it would be possible to show both on the same screenshot...
Is it really useful ?

I'm under Ubuntu Feisty so I use Firefox 2.0.0.4.
