如何改变 Nimbus 外观和感觉中的边距

发布于 2024-07-16 14:52:07 字数 673 浏览 8 评论 0原文

我正在尝试使用 Nimbus 外观和感觉，但我不能简单地将其插入以替换其他外观和感觉，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，但是以下代码不会更改任何内容。

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

其他值按预期工作。

我怎样才能删除这个填充？

我相信内容边距是指内部填充。

查看源代码外部填充似乎是硬编码的。我相信添加它是为了允许焦点选择属性。

这应该被视为一个错误吗？没有其他 L&F 可以做到这一点，并且有了这个额外的填充，就不可能重用相同的布局（因为以前的布局都假设没有填充）。

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).

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）：

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();
}

另请注意，您需要将它们设置为“LookAndFeelDefaults”而不是“开发人员”默认值。

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.

通过调用 getDefaults() 强制 nimbus 首先创建默认值：

NimbusLookAndFeel laf = new NimbusLookAndFeel();
UIManager.setLookAndFeel(laf);
UIDefaults def = laf.getDefaults();
def.put("Button.contentMargins", new Insets(0,0,0,0));
def.put("DesktopIcon.contentMargins", new Insets(0,0,0,0));
def.put("Label.contentMargins", new Insets(0,0,0,0));

如果未首先初始化默认值，UIManager.put() 不会将设置存储在 nimbus 默认值中。

Force nimbus to create the defaults first by calling getDefaults():

NimbusLookAndFeel laf = new NimbusLookAndFeel();
UIManager.setLookAndFeel(laf);
UIDefaults def = laf.getDefaults();
def.put("Button.contentMargins", new Insets(0,0,0,0));
def.put("DesktopIcon.contentMargins", new Insets(0,0,0,0));
def.put("Label.contentMargins", new Insets(0,0,0,0));

UIManager.put() won't store the settings in the nimbus defaults if the defaults was not initialized first.
