SwingでMVCアーキテクチャの限界に触れようとしていますが、試したところ、すべて（からSwingWorkerまたはRunnable#Thread）はEDTで実行されます
私の質問：
SwingWorkerいくつかの制限がありますか、または実装の順序（またはにラップされていますRunnable#Thread）によって厳密に依存していますか？JComponent＃methodがスレッドセーフかどうかは制限されていますか？
SwingのMVCアーキテクチャの本質的な特徴は？
株式会社 コンテナの再レイアウト？
注：私の場合、SSCCE私は素晴らしい例の1つを取り上げます。HFOEおそらく、この原則を厳密に保持することによって、EDTの欠如やGUIのフリーズを作成することはできません。
