範例

public class ClassA { private TextLayout textLayout; public void makeTextLayout( Device device ) { textLayout = new TextLayout( device ); if ( !textLayout.isDisposed() ) { //執行某種動作... } } }

解決方案

若要避免資源洩漏，請確定在每個 org.eclipse.swt.graphics.TextLayout 上都呼叫了 dispose()。

public class ClassA { private TextLayout textLayout; public void makeTextLayout( Device device ) { textLayout = new TextLayout( device ); if ( !textLayout.isDisposed() ) { //執行某種動作... } textLayout.dispose(); } }
