如何改变Nimbus Look and Feel的边距 [英] How can you alter the margins in Nimbus Look and Feel

问题描述

我正在尝试使用Nimbus外观和感觉，我不能简单地将其插入以替换其他外观，因为它在每个组件周围添加了一些外部填充。

所以，我想删除这个填充。这是可以更改的默认值的列表，但以下代码不会更改任何内容。

  UIManager.put（Button.contentMargins，new Insets（0,0,0,0））; 
  

其他值正在按预期工作。

如何删除此填充？

编辑

我相信内容利润率是指内部填充。

查看源代码外部填充似乎是硬编码的。我相信它已添加到允许焦点选择属性。

这应该被视为错误吗？没有其他L& F这样做，并且使用这个额外的填充，不可能重复使用相同的布局（因为之前的布局都假定没有填充）。

解决方案

我发现您必须在设置外观后立即设置这些默认值（即，在开始创建任何UI组件之前）：

 
尝试{
 UIManager.setLookAndFeel（com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel）; 
 UIManager.getLookAndFeelDefaults（）。put（Table.cellNoFocusBorder，new Insets（0,0,0,0））; 
 UIManager.getLookAndFeelDefaults（）。put（Table.focusCellHighlightBorder，new Insets（0,0,0,0））; 
 Insets buttonInsets = new Insets（3,6,3,6）; 
 UIManager.getLookAndFeelDefaults（）。put（Button.contentMargins，buttonInsets）; 
} 
 catch（例外e）{
 e.printStackTrace（）; 
} 
 

另请注意，您需要在LookAndFeelDefaults上设置它们而不是开发者默认值。

I'm trying to use Nimbus Look and Feel and I can't simply plug it in to replace other Look and feel because it adds some external padding around each component.

So, I would like to remove this padding. This is the list of defaults that can be changed, however the following code changes nothing.

UIManager.put("Button.contentMargins", new Insets(0, 0, 0, 0));

Other values are working as expected.

How can I remove this padding?

EDIT

I believe content margins is referring to the internal padding.

EDIT

Looking at the source code the external padding seems to be hard-coded. I believe it's added to allow for the focus selection property.

Should this be considered a bug? No other L&F does this, and with this extra padding it's not possible to reuse the same layout (as previous layouts all will be assuming no padding).

解决方案

I found that you have to set those defaults right after you set the look and feel (i.e., before you start creating any UI components):

try {
    UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
    UIManager.getLookAndFeelDefaults().put("Table.cellNoFocusBorder", new Insets(0,0,0,0));
    UIManager.getLookAndFeelDefaults().put("Table.focusCellHighlightBorder", new Insets(0,0,0,0));
    Insets buttonInsets = new Insets(3, 6, 3, 6);
    UIManager.getLookAndFeelDefaults().put("Button.contentMargins", buttonInsets);
}
catch (Exception e) {
    e.printStackTrace();
}

Also note that you need to set them on the "LookAndFeelDefaults" not the "developer" defaults.
