내가 만든 사용자 정의 구성 요소를 클릭하면 Dialog이 표시됩니다. 해당 클래스 이름을 ListBox으로 지정했습니다. 빈 영역을 허용 할 사용자 정의 구성 요소로 LWUIT ComboBox을 시뮬레이트하고 싶습니다. 왜냐하면 LWUIT ComboBox은 빈 영역을 허용하지 않기 때문입니다.이 상황에서 왜 대화 상자가 표시되지 않습니까?
내 ListBox 좌표가 그 아래에 더 이상 공간이 없어서 Dialog을 표시 할 때 Dialog은 표시되지 않습니다. 아래에 더 많은 공간이 있으면 Dialog이 표시됩니다. 여기
Dialog 도시되지 않을 때 상기 캡쳐 된 이미지이다 : 사용자가
ListBox 정의 촬영 한 화상에
Button S 위의 성분이다. 당신이 만약 내가 두 경우를 고려했다고 볼

ListBox 구성 요소를 추가
Form의 코드입니다 :
그리고 여기에는 코드입니다 공간 또는 ListBox 클래스의 pointerPressed 메서드의 ListBox 아래에 있지 않습니다.
내가 컨테이너에 대한 addComponent가 cz5 통해 CZ1 호출 Form의 코드를 작성하지
Dialog 아주 잘
ListBox 구성 요소 아래에 표시됩니다.
하단에 공간이 없는데 왜 Dialog이 표시되지 않습니까?
아래에 공간이없는 경우 맨 아래 변수를 설정할 때 실수를했습니다 : 'bottom = preferredHeight + espaceVertRestant;'로 바꾸고 작동합니다! 감사 –
