私は(あなたの最後の3つの質問から)本当に迷ってしまいました、
をすることができ、我々はあなたが3本の場合には、1つのGUIのためModels
を離れてしまっていることを想像しますが、変更する場合は重要ではないんGUIの要素数、または1 JComponent
のプロパティを変更、
PropertyChangeListener
からの出力はかなり出力が確認してくださいEDT

してくださいあなたの最後の3つの質問は約1です)JComponentの、またはモデルについて、2)問題とモデルからJComponentの通知、3)あなたの現在の状況は、モデル要素の別の番号が含まれていることですGUIとの比較で – mKorbel
