JTabbedPane 选项卡高度与 nimbus
我想更改高度选项卡的选项卡窗格，为此我尝试了多种方法但没有成功。首先，我尝试使用间隔图标，高度很好，但选项卡的文本不再居中。然后我尝试更改 Nimbus L&F 属性、TabbedPane.tabInsets、TabbedPane:TabbedPaneTab.contentMargins 和 TabbedPane:TabbedPaneTabArea.contentMargins 没有任何变化。最后我尝试扩展BasicTabbedPaneUI并覆盖calculateTabHeight，但选项卡的背景不再绘制。
I would like the change the height tab's tabbedpane, and to do so I tried several method without any success. First I tried with a spacer icon, the height is good, but the text of the tab is not center anymore. Then I tried to change Nimbus L&F properties, TabbedPane.tabInsets, TabbedPane:TabbedPaneTab.contentMargins, and TabbedPane:TabbedPaneTabArea.contentMargins nothing change. Finally I tried to extend BasicTabbedPaneUI and overide calculateTabHeight, but the background of the tab is not painted anymore.

只需使用
setTabComponentAt在选项卡上设置自定义组件即可。您可以设置任何您想要的组件。如果您只想要一个更大高度的标签，请为setComponentAt提供一个带边框的 JLabel，或者设置其 PreferredSize。Just use
setTabComponentAtto set a custom component on the tab. You can set any component you want. If you just want a label with a bigger height, givesetComponentAta JLabel with a border, or with its preferredSize set.
