如何设置JTabbedPane选项卡背景和前景,高度和宽度(选中和未选中选项卡)

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) );

这是一个密钥列表

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,还有一些其他的Nimbus默认值,如:

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