Hi tonikitoo,
Thanks for your hint. It seems that WebKit doesn't support the windowless
plugin in X11.
Is their other way to implement feature? We can get some infomation of the
native windows now.
Can we do it with raw Xlib functions?
I found a topic in MDC that claims the support of windowless plugins in X11.
