java - 删除 Substance LAF 中 JTabbedPane 上的内容填充

Question

我正在使用 Substance LAF 进行一些实验，并尝试删除选项卡之间的填充。我使用的默认用户界面:

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值。如何用 Substance 达到同样的效果。

Answer 1

• 无法使用 JTabbedPane 的 UIManager 覆盖此值，

• 这是一个很常见的问题，大多数方法都受到保护(如果它们在 UIManager 中作为键发布并不重要)，而不覆盖自己的 BasicTabbedPaneUI

• 物质

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

• 金属(跨平台)

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

• 雨云

null
null

系统(Java6 上的 win8)

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

• 键值的格式是否为 Instets(0,0,0,0) 或 InsetsUIResource(0,0,0,0) 并不重要
