如何在 Java 中为 JTextPane 文本设置字体、样式、大小和颜色
对于 JTextPane 的背景色和前景色,请使用以下代码——
JTextPane textPane = new JTextPane(); textPane.setBackground(Color.blue); textPane.setBackground(Color.green);
对于字体、样式和大小,请使用 Font 类并设置字体——
Font font = new Font("Serif", Font.ITALIC, 18); textPane.setFont(font);
以下是在 JTextPane 中为文本设置字体、样式和颜色的示例——
示例
package my; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Container; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTextPane; import javax.swing.text.BadLocationException; import javax.swing.text.SimpleAttributeSet; import javax.swing.text.Style; import javax.swing.text.StyleConstants; import javax.swing.text.StyledDocument; public class SwingDemo { public static void main(String args[]) throws BadLocationException { JFrame frame = new JFrame("Demo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Container container = frame.getContentPane(); JTextPane textPane = new JTextPane(); textPane.setBackground(Color.blue); textPane.setBackground(Color.green); SimpleAttributeSet attributeSet = new SimpleAttributeSet(); StyleConstants.setItalic(attributeSet, true); textPane.setCharacterAttributes(attributeSet, true); textPane.setText("World Cup Cricket begins from "); Font font = new Font("Serif", Font.ITALIC, 18); textPane.setFont(font); StyledDocument doc = textPane.getStyledDocument(); Style style = textPane.addStyle("", null); StyleConstants.setForeground(style, Color.red); StyleConstants.setBackground(style, Color.white); doc.insertString(doc.getLength(), "30th May ", style); StyleConstants.setForeground(style, Color.yellow); StyleConstants.setBackground(style, Color.gray); doc.insertString(doc.getLength(), "2019", style); JScrollPane scrollPane = new JScrollPane(textPane); container.add(scrollPane, BorderLayout.CENTER); frame.setSize(550, 300); frame.setVisible(true); } }
