Samples unix-basic BasicPlugin not working #12

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
The unix basic plugin compiles fine shows up in firefox and chrome. 

When runing a page with the plugin it doesnt show anything but it doesnt crash 
either.

Through the command line chrome is giving this

(exe:1334): Gdk-CRITICAL **: IA__gdk_gc_new: assertion `drawable != NULL' failed

(exe:1334): Gdk-CRITICAL **: IA__gdk_gc_set_rgb_fg_color: assertion `GDK_IS_GC

I got the problem narrowed down I dont know the solution but the problem is 
happening on this line at least from what I can tell

GdkDrawable* gdkWindow = GDK_DRAWABLE(gdk_window_foreign_new(nativeWinId));

gdk_window_foreign_new seems to be returning null

This patch mostly fixes it. The issue was that the Drawable could be either a 
Pixmap or a Window. Newer browsers do out-of-process stuff and pass a Pixmap, 
but Firefox <4 in in-process plugin mode just passes in the Window.

This works for me in Firefox and WebKitGtk. Unfortunately, this doesn't work 
for me in Chrome for some reason. It renders, but most of the plugin ends up 
being transparent. I poked at it a bit Chrome-side but haven't figured out 
what's wrong.

(There is also another issue with QtWebKit, but it probably deserves its own 
bug. The plugin doesn't link to libgdk-x11-2.0.so.0, so QtWebKit can't load it. 
Once that's there, QtWebKit only calls gtk_init for Flash and nspluginwrapper. 
If you have one of those installed, it all works. If not, gtk_init never gets 
called. Not sure whose bug that should be considered.)
