Dear Enlightenment Users,
I've made some progress, but seem to have hit a wall and would appreciate some
help.
I'm using the genlist_example_02 program from Elementary as a starting point
(no particular reason, I just had it open in an editor).
I was able to use software buffer engine, by adding the following changes:
ee = ecore_evas_new("buffer", 0, 0, WIDTH, HEIGHT, NULL);
win = elm_win_fake_add(ee);
// win = elm_win_util_standard_add("genlist", "Genlist - simple");
// elm_policy_set(ELM_POLICY_QUIT, ELM_POLICY_QUIT_LAST_WINDOW_CLOSED);
// elm_win_autodel_set(win, EINA_TRUE);
(Is this even the right way to do it??)
I can save a PPM format image from the ee canvas contents. The
genlist_example_02 output appears in the image.
Next, with some custom code, I'm reading key down/up events from Linux
/dev/input/* devices, converting them to Ecore_Event_Key objects, and then
sending them using:
ecore_event_add(ECORE_EVENT_KEY_DOWN, e, NULL, NULL);
and
ecore_event_add(ECORE_EVENT_KEY_UP, e, NULL, NULL);
However, the key strokes do not have any effect on the GUI widgets in the
genlist_example_02 program.
If I revert to the original code (not use buffer engine) then the key strokes
work fine.
To verify the keycodes were correct, I added some callbacks like this:
ecore_event_handler_add(ECORE_EVENT_KEY_DOWN, keyEventHandlerCb, &ctx);
ecore_event_handler_add(ECORE_EVENT_KEY_UP, keyEventHandlerCb, &ctx);
Everything matches, except the window, event_window and root_window fields of
the Ecore_Event_Key object are different from my generated events.
Using efl-1.17.2 and elementary-1.17.1
What am I doing wrong??
Basically, I want to manipulate the GUI widgets with the keyboard as usual, but
have the graphics rendered in a memory buffer.
Any help appreciated.
Thank you,
Markus

Subject: [e-users] Elementary program / generating keyboard input events
Dear Enlightenment Users,
Is it possible to manually generate keyboard input events?
In my case, keyboard events are received via a pipe from an external
application. The standard Linux input events are not available. Instead I would
like to take the keyboard events and feed them into the Elementary event loop
somehow.
I am new to Elementary and Enlightenment. Any guidance would be much
appreciated.
Thank you and best wishes,
Markus
