キーボードの入力に問題があります。私はKeyActionListenerを書きましたが、マウスでいくつかのボタンをクリックした後にしか動作しません。たとえば、マウス5で押してからキーボードを押すと、記号がキーボードで押されますが、プログラムが起動した後、私は何も手に入れません。ここでkeybordで押されたシンボルをjavaのラベルに入力する方法は？
は私のコードです：

はまた、どのように私は、彼らが同じ大きさになることを、ので、私の左と右のボタンをレイアウトすることができますか？私の操作は私に良い結果を得ることができた、私はまだ別のサイズと右のボタンをメモリボタンがあります。ここではイメージがある：あなたのコード内
* *回のカップルをタブ移動してください「それは私がマウスでいくつかのボタンをクリックした後にのみ機能します」。フォーカスは、GUIの上部にある「タブのような」ものに焦点を当てているかもしれません。 –
Andrew Thompson、ありがとう、はい、私はこれについて知っていますが、どうやってタブビングなしにこれを行うことができますか？ – DPS
