我的问题是,我可以更改我的JOptionPane的字体大小和样式,使我的列表字体更大,非常感谢任何提示。 Thanks.
谢谢。
If you want all JOptionPane
s to have the same font style and size, you can change the property of the UIManager
with: 如果您希望所有
JOptionPane
具有相同的字体样式和大小,您可以使用以下命令更改UIManager
的属性:
javax.swing.UIManager.put("OptionPane.font", new Font("yourFontName", Font.BOLD, 30));
To get a list of the available font names, use the following snippet: 要获取可用字体名称的列表,请使用以下代码段:
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fontNames = ge.getAvailableFontFamilyNames();
for (int index = 0; index < fontNames.length; index++)
{
System.out.println(fontNames[index]);
}
One of the easiest ways is to use HTML directly in the String literal. 最简单的方法之一是直接在String文字中使用HTML。 For example:
例如:
"MINES AND GEOSCIENCES BUREAU - REGION XI, DAVAO CITY\\n"
Can easily become: 很容易变成:
"<html><span style='font-size:2em'>MINES AND GEOSCIENCES BUREAU - REGION XI, DAVAO CITY"
Note that when you use HTML, you can no longer use \\n
for new lines. 请注意,使用HTML时,您不能再使用
\\n
表示新行。 Use <br>
instead. 用
<br>
来代替。
