如何设置JTabbedPane标签背景和前景，高度和宽度（选中和未选中标签）

Answer 1

您可以为UIDefaults设置新值：

        UIDefaults def = UIManager.getLookAndFeelDefaults();
        def.put( "TabbedPane.foreground", Color.RED );
        def.put( "TabbedPane.textIconGap", new Integer(16) );
        def.put( "TabbedPane.background", Color.BLUE );
        def.put( "TabbedPane.tabInsets", new Insets(10,10,10,10) );
        def.put( "TabbedPane.selectedTabPadInsets", new Insets(10,20,10,20) );

这是一个键列表

TabbedPane.textIconGap
TabbedPane.contentOpaque
TabbedPane.focus
TabbedPane.foreground
TabbedPane.tabRunOverlay
TabbedPane.shadow
TabbedPane.darkShadow
TabbedPane.background
TabbedPane.ancestorInputMap
TabbedPane.focusInputMap
TabbedPane.tabInsets
TabbedPane.light
TabbedPane.contentBorderInsets
TabbedPane.tabsOverlapBorder
TabbedPane.tabsOpaque
TabbedPane.tabAreaInsets
TabbedPane.highlight
TabbedPane.font
TabbedPane.selectedTabPadInsets

对于Nimbus LookAndFeel，还有其他一些Nimbus Defaults喜欢：

      TabbedPane:TabbedPaneTabArea.contentMargins
      TabbedPane:TabbedPaneTabArea[Enabled].backgroundPainter
      TabbedPane:TabbedPaneTab[Selected].backgroundPainter
      TabbedPane:TabbedPaneTabArea[Enabled].backgroundPainter
      TabbedPane:TabbedPaneTab.contentMargins
      TabbedPane.tabOverlap

Answer 2

更改标签高度和宽度的一种方法是在标签的标签中使用HTML和/或CSS。为此，您可以在HTML“span”或“p”元素中使用CSS填充属性。

Answer 3

您可以按如下方式控制高度：

JTabbedPane tabs = new JTabbedPane();
tabs.setUI(new BasicTabbedPaneUI() {
    @Override
    protected int calculateTabHeight(int tabPlacement, int tabIndex, int fontHeight) {
        return 45; // manipulate this number however you please.
    }
});

如果每个标签需要不同的高度，这个答案也可能有用：How to handle the height of the tab title in JTabbedPane
