SWT 컴포지트가 창에서 최대화되지 않음

Question

Neon Eclipse의 windowbuilder에서 SWT Jface Java 프로젝트로 작업합니다. 이벤트 핸들러에 대해 표시되는 셸에 2 개의 Composite가 있습니다.

컴포지트

이벤트 핸들러에 의해 표시되어 있지만, 이벤트 핸들러가 다시 설정되는 것을 제외하고 창을 최대화하면서 복합 더이상 보이지 않는다.

창가에서 합성물을 볼 수있게하려면 어떻게해야합니까?

Answer 1

StackLayout을 쉘의 레이아웃으로 지정했습니다. 이렇게하면 한 번에 하나의 하위 컨트롤 만 표시 될 것이므로 topControl 필드를 표시 할 컨트롤로 설정해야합니다. StackLayout을 혼동 할 것이다이 같은 복합의에 setVisible를 호출하지 마십시오

StackLayout layout = new StackLayout(); 
shellSistemaInvestimentos.setLayout(layout); 

... 

layout.topControl = compositeAcoesCompra; // whichever control you want to show

그래서 당신이 뭔가를 할 필요가있다.
