Simulate a key press event?

[Yu Feng <rainwoodman gmail com>]

Dear list,

Could anyone help me to redirect a key press event from another
application's window to a GtkWidget?

My current solution (which works with a lot of warnings) is

1 Create a Gdk Foreign Window on the XID of the to be grabbed window.
2 Add a gdk filter on the foreign gdk window,
3 Grab the key with XGrabKey
4 in the filter, switch-case on the KeyPress event,
5 change the target window of XEventKey to the GtkWidget's window's xid
event->window = xwin
6 XSendEvent(display, xwin, false, 0, event)

For each redirected key press, the warning is

(lt-GlobalMenu.PanelApplet:19592): Gdk-WARNING **:
gdk_window_set_user_time called on non-toplevel

It is thrown by the set_user_time line immediate after
gtk_key_translate.

How can I avoid them?

Regards,

Yu
