Hi Bharathwaaj, I'm a developer of gtk2hs (Haskell binding to gtk+). I have fix same problem (WebKit widget and GdkEvent) at Haskell side. (https://patch-tag.com/r/AndyStewart/gtk-serialized-event/snapshot/current/content/pretty/Graphics/UI/Gtk/Gdk/SerializedEvent.hsc) This is screenshot : http://farm5.static.flickr.com/4080/4758242386_5230d3d54d_b.jpg Though i use Haskell, but i can explain how to pass GdkEvent from one process to another. Below are step: 1) Serialize GdkEvent at *server* process. 2) Then send SerializeEvent over the network 3) When *client* process receive SerializeEvent from network, re-build GdkEvent. 4) Then you can use gtk_main_do_event propagate same event on current focus widget, or use gtk_widget_event propagate event on specify widget. Only trick is you need use idle_add_full wrap gtk_main_do_event to make sure gtk_main_do_event running in *main thread* and not *listen event thread*. Hope above will help you. :) Cheers, -- Andy Bharathwaaj Srinivasan <bharathwaaj.s@xxxxxxxxx> writes: > Hi, > > Is it possible to send GdkEvents to a GtkWidget from the application? > > Currently I've a GIOChannel which is listening to a socket and the GSource is attached to the Glib > main loop. > > g_type_init(); > g_thread_init(NULL); > gdk_threads_init(); > gdk_threads_enter(); > gtk_init(NULL, NULL); > > channel = g_io_channel_unix_new (fd); > g_io_channel_set_encoding (channel, NULL, NULL); > g_io_channel_set_buffered (channel, FALSE); > > source = g_io_create_watch (channel, G_IO_IN); > g_source_set_priority (source, G_PRIORITY_DEFAULT); > g_source_set_can_recurse (source, TRUE); > g_source_set_callback (source, (GSourceFunc) event_handler, NULL, NULL); > g_source_attach (source, NULL); > > g_source_unref (source); > g_io_channel_unref(channel); > > gtk_main(); > gdk_threads_leave(); > > GdkEvents (Keyboard events) are passed from say another process by writing to the socket fd. > > Glib calls the callback "event_handler" for data available to read.
