我正在创建一个类似于gedit的文本编辑器。在工具栏中，我使用了10个带图标的按钮。我正在使用JFrame和BorderLayout。工具栏位于北部。但问题是，按钮变得太大，工具栏几乎覆盖了一半的框架。所有的图标大小为512x512px。我尝试调整图标大小，但它没有奏效。如果图像的图标被删除，它会正常工作。跨越JFrame的一半的JToolBar

你有什么，所以任何适当的大小远吗？ – Anptk 2014-11-08 09:42:34
我有一个菜单栏，一个作为状态栏的标签在南方，jtabbedpane在中心。 tabbedpane有jscrollpane作为每个选项卡，其中包含一个jtextarea。 – SanketB 2014-11-08 09:44:30
