私はJListでサイズ変更の問題を抱えています...以下は私のコードです...私の要件は、固定サイズのJListをパネルに追加することであり、フレームを最大化/最小化すると、JListはそれに応じて増減する必要があります.助けてください..これを達成する方法は？
以下はデザインです。
こんにちはカール、単純なケースでは機能しますが、上記のケースでは機能しません。だから私は今、上記のコードを説明しています..
GBレイアウトの「TestListControl」というフレームがあります。GB レイアウトの selectDevicesPanel を追加します。selectDevicesPanel で: GB レイアウトで selectNamesInnerPanel を追加する selectNamesInnerPanel で: GB レイアウトで selectNameAddPanel を追加する フロー レイアウトで selectTeamPanel を追加する selectNameAddPanel で: chooseDeviceScrollPane clickToAddDeletePanel selectedNameScrollPane
