Simple event test(mouse down/focus) using Evas

[목차로 이동] Enlightenment Foundation Language

focus 테스트를 위해 [EFL] 3. Simple Application using Evas. 를 가지고 간단한 이벤트 테스트를 해보기로 했습니다

컴파일은 아래와 같이 하면 됩니다.
gcc -c simple simple.c `pkg-config --cflags --libs evas ecore-evas`

결론:

  - evas_object에서는 focus를 수동으로 옮겨주어야 한다.

    (elementary는 아님)
