eclipse 플러그인 확장하기 : 메뉴를 활성화하고 비활성화하는 방법?

Question

첫 번째 메뉴에 대한 프로세스가 완료되면 두 번째 및 일곱 번째 메뉴를 활성화하고 싶습니다. 두 번째 메뉴에 대한 프로세스가 완료되면 내 3, 7 번째 메뉴를 활성화하고 싶습니다. 나는 7 개의 메뉴를 가지고있다. 처음에는 첫 번째 메뉴 만 활성화되어 있어야하고 나머지는 비활성화되어야하며 첫 번째 프로세스가 완료되면 두 번째로 첫 번째 메뉴, 두 번째 메뉴 및 일곱 번째 메뉴 만 활성화해야합니다.

내가 예상 한대로 작동하려면 내 plugin.xml을 어떻게 변경해야하는지 알지 못합니다. 내 plugin.xml 코드입니다. 도와 주시고 미리 감사드립니다.

Answer 1

각 명령에 대한 handler에 enabledWhen 표현으로이 작업을 수행 할 것입니다. enabled when 표현식에 대한 사용자 정의 테스트를 정의하기 위해 속성 테스터를 사용해야하는 것 같습니다.

<extension point="org.eclipse.core.expressions.propertyTesters"> 
    <propertyTester 
    id="documentation.propertytester" 
    type="java.lang.Object" 
    namespace="documentation" 
    properties="handler1enabled,handler2enabled,handler3enabled.. and so on ..." 
    class="documentation.PropertyTester"> 
    </propertyTester> 
</extension> 

당신은 다음 속성 테스트를 할 수있는 documention.PropertyTester 클래스를 코드 :

사용 org.eclipse.core.expressions.propertyTesters는 특성 시험기, 같은 것을 정의합니다.

당신은 다음에서 사용할 수있는이 같은 표현이 때 사용 : ". 프로세스가 첫 번째 메뉴에 대한 완료"로 무엇을 의미합니까

<handler 
     class="documentation.handlers.SampleHandler5" 
     commandId="documentation.handlers.SampleHandler5"> 
    <enabledWhen> 
     <test 
       property="namespace.handler5enabled"> 
     </test> 
    </enabledWhen> 
</handler>
