A round trip is sufficient here. We need to make sure that the server
has received the wl_test request and that we've received the event
that the request triggers. The wl_display_roundtrip() helper does
exactly that: it sends a wl_display.sync request, which will hit the
server after the wl_test requests and thus the wl_callback.done event
will come back after the server has seen all the previous requests and
after we've handled all preceeding event.
wl_test_send_button(client->test->wl_test, BTN_LEFT,
WL_POINTER_BUTTON_STATE_PRESSED);
- yield(client);
+ wl_display_roundtrip(client->wl_display);
assert(pointer->button == BTN_LEFT);
assert(pointer->state == WL_POINTER_BUTTON_STATE_PRESSED);
wl_test_send_button(client->test->wl_test, BTN_LEFT,
WL_POINTER_BUTTON_STATE_RELEASED);
- yield(client);
+ wl_display_roundtrip(client->wl_display);
assert(pointer->button == BTN_LEFT);
assert(pointer->state == WL_POINTER_BUTTON_STATE_RELEASED);
}
