GtkWindow XID

Rate this Message:
Hi,
I'm trying to use gstreamer in a simple java-gnome app by using gstreamer-java. But to be able to embed a video into a Window I've to get back its native xid. So, I modified Java-gnome to implement this: in GtkWindow.java I added: static public final long getWindowXID (Window w){ return pointerOf(w); } and in Window.java I added: public long getWindowXID (){ return GtkWindow.getWindowXID(this); } But when I use this id to embed the video X says BadWindow. Am I getting the xid the right way ? Thanks in advance ------------------------------------------------------------------------------ Come build with us!

Without that accesor you will not be able to take the XID of a window. Here's an example on how to embed Gstreamer in a custom Gtk2 application: http://github.com/potyl/perl-GStreamer-Interfaces/blob/master/examples/gst-video-sample.pl The code in Perl, but you should be able to understand easily what's going on.

Check with ldd if the java-gnome .so is linked with gdk-x11 If ldd doesn't show the file then it isn't linked. Try to link it your self by hand: rm tmp/libgtkjni-*.so LDFLAGS=`pkg-config --libs gdk-x11-2.0` build/faster If ldd shows the file in the dependency list then there's something strange going on. -- Emmanuel Rodriguez ------------------------------------------------------------------------------ Come build with us!
