示例

public class ClassA { private GC gc; public void makeGC( Drawable drawable ) { gc = new GC( drawable ); if ( !gc.isDisposed() ) { //do something... } } }

解决方案

为了避免资源泄漏，请确保对每个 org.eclipse.swt.graphics.GC 都调用 dispose()。 注意：此规则适用于所有形式的 GC 构造函数。

public class ClassA { private GC gc; public void makeGC( Drawable drawable ) { gc = new GC( drawable ); if ( !gc.isDisposed() ) { //do something... } gc.dispose(); } }
