我正在創建一個類似於gedit的文本編輯器。在工具欄中，我使用了10個帶圖標的按鈕。我正在使用JFrame和BorderLayout。工具欄位於北部。但問題是，按鈕變得太大，工具欄幾乎覆蓋了一半的框架。所有的圖標大小爲512x512px。我嘗試調整圖標大小，但它沒有奏效。如果圖像的圖標被刪除，它會正常工作。跨越JFrame的一半的JToolBar

你有什麼，所以任何適當的大小遠嗎？ – Anptk 2014-11-08 09:42:34
我有一個菜單欄，一個作爲狀態欄的標籤在南方，jtabbedpane在中心。 tabbedpane有jscrollpane作爲每個選項卡，其中包含一個jtextarea。 – SanketB 2014-11-08 09:44:30
