示例

public class ClassA { private Region region; public void makeRegion( Device device ) { region = new Region( device ); if ( !region.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.Region 都调用 dispose()。 注意：此规则适用于所有形式的 Region 构造函数。

public class ClassA { private Region region; public void makeRegion( Device device ) { region = new Region( device ); if ( !region.isDisposed() ) { //do something... } region.dispose(); } }
