如何在Java中为JTextPane设置样式？

How to set style for JTextPane in Java?

要为JTextPane中的文本设置样式，请使用setItalic()或setBold()分别为字体设置斜体或粗体样式。

以下是我们的JTextPane组件-

1	JTextPane pane = new JTextPane();

现在，使用StyleConstants类为上面创建的JTextPane设置样式。我们还设置了背景和前景色-

SimpleAttributeSet attributeSet = new SimpleAttributeSet();
StyleConstants.setItalic(attributeSet, true);
StyleConstants.setForeground(attributeSet, Color.black);
StyleConstants.setBackground(attributeSet, Color.orange);
pane.setCharacterAttributes(attributeSet, true);
