示例

public class ClassA { private Pattern pattern; public void makePattern( Device device, Image image ) { pattern = new Pattern( device, image ); if ( !pattern.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.Pattern 都调用 dispose()。 注意：此规则适用于所有形式的 Pattern 构造函数。

public class ClassA { private Pattern pattern; public void makePattern( Device device, Image image ) { pattern = new Pattern( device, image ); if ( !pattern.isDisposed() ) { //do something... } pattern.dispose(); } }
