How do I get the default font for Swing JTabbedPane labels?
提问by Paul Reiners
Does the text in Swing components have a default font? In particular, what about tab labels on JTabbedPanes?
Swing 组件中的文本是否具有默认字体？特别是，JTabbedPanes上的标签标签呢？
I'm working on a mock-up of a GUI made with Swing and want it to blend it with a screen image I grabbed of a Swing app.
我正在制作一个用 Swing 制作的 GUI 模型，并希望它与我从 Swing 应用程序中抓取的屏幕图像混合。

It depends on the Look and Feel. If it's an application you've written, get the values from UIManager.getDefaults().getFont("TabbedPane.font")
这取决于外观和感觉。如果它是您编写的应用程序，请从UIManager.getDefaults().getFont("TabbedPane.font")

It looks like it's Arial. That's what Identifonttells me and it looks right.
好像是阿里的。这就是Identifont告诉我的，它看起来是对的。

The UIManager Defaultsshows what the values are for all properties for all components (including "TabbedPane.font").
该UIManager的默认显示什么值是所有组件（包括“TabbedPane.font”）的所有属性。

Based on the answer of Reverend Gonzo, this piece of code lets you know what keys are in the UIDefaults. As the keys are self-explanatory, you know what key you can use. I had to know the key for the JTextField font, for example, and could only find it this way.
根据 Reverend Gonzo 的回答，这段代码让您知道 UIDefaults 中有哪些键。由于键是不言自明的，因此您知道可以使用什么键。例如，我必须知道 JTextField 字体的键，并且只能通过这种方式找到它。
Set<Object> keys = UIManager.getDefaults().keySet();
for (Object key : keys) {
if (key instanceof String && ((String) key).contains("font")) {
System.out.println(key + "=" + UIManager.getDefaults().get(key));
}
}
If you're looking for a font, in your case, just cast the key to a String and check whether it contains the word "font". This way you narrow the set of keys you have potential interest for.
如果您正在寻找一种字体，就您而言，只需将键转换为字符串并检查它是否包含“字体”一词。通过这种方式，您可以缩小您可能感兴趣的密钥集。
I got a list
我有一份清单
- Menu.font=...

- Menu.font=...
- TextField.font=...
- RadioButtonMenuItem.font=...
- 工具提示.font=...
- TitledBorder.font=...
- ...
- TabbedPane.font=...
- ...
And thus you would need to pick TabbedPane.font.
因此，您需要选择 TabbedPane.font。
