Java - 將JFrame傳輸到JPanel

我有擴展JFrame的視頻播放器類，因爲我需要在舞臺（使用SwingNode的Jafafx）中運行此幀，所以我需要將此類傳遞給JPanel。這可能嗎？我試圖改變，但在EventHangler類中創建問題，而「visualComponent」不在面板中顯示，只有controlsComponent。Java - 將JFrame傳輸到JPanel

要關閉的JFrame變成一個JPanel做到以下幾點：

更改「公共類MediaPlayerDemo擴展JFrame的」到「公共類MediaPlayerDemo擴展JPanel」
刪除秀（）,setSize（..） and app.addWindowListener（..）
替換「的getContentPane（）」與「這個」

編輯：你也應該更換超（「展示了Java媒體播放器」）;與super（新的BorderLayout（））;- 埃裏克Leibenguth

而且顯示（在JFrame中）已被棄用，這意味着你不應該使用它。使用setVisible（true）;

您還可以用框架替換您的窗口關閉事件。 setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）;

祝您的視頻播放器順利！

這還不夠，仍然有錯誤... – Ramz

有什麼錯誤？（我不熟悉你正在使用的庫） – ArgonBird18

你也應該用'super（new BorderLayout（））'替換'super（「演示Java媒體播放器」）;'' –
