我想添加一個背景圖像到我的frame.But當我添加一個圖像到我的框架它已成功添加,但其他東西,如j標籤和按鈕添加到框架afterwords不會出現在框架上。我在桌面上保留了圖像。下面是我的代碼JFrame背景圖背景圖像設置時,其他按鈕不顯示在圖像上的圖像?

EditTeamInterface的構造,可以設置使用setContentPane(contentPane);框架中的內容窗格中,但在static void main,你

frame.setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("C:/Users/Abdullah/Desktop/cricketBackGround1.jpg"))))); 

更換這會放棄你做的一切之前對於這個新的內容...

而不是EditTeamInterfaceJFrame延伸,改變它,使它從JPanel

創建JFrame的新實例,將內容窗格設置爲您的標籤,然後將EditTeamInterface添加到框架。

因爲JLabel沒有默認的佈局管理器,你應該叫setLayout(new BorderLayout())在框架上後,你設置它的內容窗格標籤

雖然使用JLabel,這樣一來將工作,JLabel將不計算它的首選大小是基於其內容的需求,而是基於icontext的屬性。這並不能真正適合這項任務。

更好的解決方案是使用自定義JPanel並覆蓋它的paintComponent來渲染所需的圖像。如果你聰明,你會做到這一點,以便這個班級可以重複使用。
