Question

我正在使用Substance LAF进行一些实验，我正在尝试删除标签之间的填充。使用默认的ui：

UIManager.getDefaults().put("TabbedPane.contentBorderInsets", new Insets(0,0,0,0));
UIManager.getDefaults().put("TabbedPane.tabsOverlapBorder", true);

，但这不适用于Substance，它似乎提供了自己的价值。如何与Substance达到同样的效果。

Answer 1

使用UIManager for JTabbedPane无法覆盖此值，
这是一个非常普遍的问题，大多数方法都受到保护（如果它们作为UIManager中的键发布并不重要）而不覆盖自己的BasicTabbedPaneUI

物质

enter image description here

javax.swing.plaf.InsetsUIResource[top=4,left=4,bottom=4,right=4]
false

金属（跨平台）

enter image description here

java.awt.Insets[top=4,left=2,bottom=3,right=3] 
false

雨云

enter image description here

null
null

系统（Java6上的win8）

enter image description here

javax.swing.plaf.InsetsUIResource[top=2,left=2,bottom=3,right=3]
true

Instets(0,0,0,0)

无关紧要

Answer 2

感谢@mKorbel提供的信息，我发现通过使用可以达到同样的效果将SubstanceLookAndFeel.TABBED_PANE_CONTENT_BORDER_KIND设置为SubstanceConstants.TabContentPaneBorderKind.SINGLE_PLACEMENT
