我已經創建了我的黑莓應用程序GridFieldManager，我想設置一個邊界的每個細胞，使電網看起來像一個Excel網格。黑莓GridFieldManager邊境
我使用：
gridFieldManager.setBorder（BorderFactory.createSimpleBorder（新XYEdges（0，0，0，0），Border.STYLE_DASHED））;
但是這只是設置邊界周圍的經理，而不是每個單元格。
感謝您的幫助。
只是設置邊框的每個Field添加到GridFieldManager。
創建第一邊框添加集到正在添加到管理器Field的方法，然後將它傳遞給加（）。或從GridFieldManager子類並覆蓋add(Field f)邊境設置爲正在添加一個Field（f），然後調用super.add(f)。
我用下面的代碼來創建UI進行了填字遊戲... 我定製電網 它仍然有一些問題（滾動的問題），但它應該ATLEAST給你什麼做的一些想法：
