How to stylize (make bold) text in a JTextArea?

问题

JTextArea txt = new JTextArea();
    StringBuffer sb = new StringBuffer();
    sb.append("Employee Information");
    sb.append("\n");
    sb.append("Name:");
    txt.setText(sb.toString());

Here I need to set "Employee Information" to BOLD format..How to do that.. I tried like this

 sb.append("<html><b>Employee Information</b></html>");

But its printing the text normally... how to make bold?

回答1:

The JText Area is a plain text area, for styled text areas you need something like JEditorPane or JTextPane, take a look at the Documentation

回答2:

You can use the setFont method. For your example try :

Font font = txt.getFont();  
txt.setFont(font.deriveFont(Font.BOLD));

(Keep in mind that txt is the JTextArea, not your actual text.)
