我正在創建一個程序來跟蹤DVD的列表。在主頁上我設置了2個JButton。當用戶點擊一個新的DVD時,一個來自另一個類的新JFrame會出現字段以輸入有關新DVD的信息。我試圖在第二個框架上做一個取消按鈕,這樣當你點擊取消按鈕時,它將恢復主GUI並關閉新的條目GUI。代碼如下,我不知道如何去做。如何在不關閉主程序的情況下關閉jframe

好吧,我改變了在框架SETT但現在我根本無法關閉窗戶。我可以使用哪些編碼,以便取消按鈕關閉窗口。 SUDO if actionperformed ==取消按鈕 Jframe.createEntry.Close 或類似的東西 – Jon 2010-11-24 16:11:04
frame.setVisible(false); frame.dispose() – dacwe 2010-11-25 12:21:47
