terminator cannot receive compose key events with input method in Wayland
Terminator can have multiple panes in the window and it can forward key events on the active pane (input focus) to other panes (input focuses).
The source tarball is available at https://launchpad.net/terminator/gtk3/
Terminator connects the 'key-press-event' signal on
VTE and receives the key events before
GtkIMModule receives the key events and forward the key events:
mutter clutter receives key events before VTE receives them in Wayland so Terminator cannot receive compose key events.
terminatorin GNOME Wayland
Ctrl-Shift-oto split the window with two panes.
Alt-aand to forward key events on the active pane to another.
And terminator cannot receive the compose key events.
E.g. Multi_key-'-a outputs "á".
TRUE in the compose key sequences and
clutter_input_method_notify_key_event() does not forward the compose key events.
IBus GTK IM module (ibus/client/gtk3/ibusimcontext.c) calls
gtk_key_snooper_install() by default and input method engines always receive the key events before terminator does.
But when users set
IBUS_DISABLE_SNOOPER=1 environment variable, IBus GTK IM module uses
GtkIMContextClass.flter_keypress() instead of the snooper and terminator can receives the key events before input methods do.
Do you have any ideas that terminator can receives the key events before ClutterInputMethod does?
