我无法找到访问
Windows字体或预定义字体和大小的东西.所以对于我的java程序,我有一个JComboBox的字体,大小和颜色.问题是我需要预先输入字体,大小和颜色.我将如何获得预定义的字体,颜色和大小？到目前为止,这是我的这种字体,但它不是正确的方式.
if (font.equals("Arial")) {
if (size.equals("8")) {
setSize = 8;
} else if (size.equals("10")) {
setSize = 10;
} else if (size.equals("12")) {
setSize = 12;
}
if (color.equals("Black")) {
setColor = Color.BLACK;
} else if (color.equals("Blue")) {
setColor = Color.BLUE;
} else if (color.equals("Red")) {
setColor = Color.red;
}
Font font = new Font("Arial",setAttribute,setSize);
Writer.setFont(font);
Writer.setForeground(setColor);
解决方法
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); String[] fonts = ge.getAvailableFontFamilyNames();
可以在运行时设置大小和样式.
例如.
import java.awt.*;
import javax.swing.*;
class ShowFonts {
public static void main(String[] args) {
SwingUtilities.invokeLater( new Runnable() {
public void run() {
GraphicsEnvironment ge = GraphicsEnvironment.
getLocalGraphicsEnvironment();
String[] fonts = ge.getAvailableFontFamilyNames();
JComboBox fontChooser = new JComboBox(fonts);
fontChooser.setRenderer(new FontCellRenderer());
JOptionPane.showMessageDialog(null,fontChooser);
}
});
}
}
class FontCellRenderer extends DefaultListCellRenderer {
public Component getListCellRendererComponent(
JList list,Object value,int index,boolean isSelected,boolean cellHasFocus) {
JLabel label = (JLabel)super.getListCellRendererComponent(
list,value,index,isSelected,cellHasFocus);
Font font = new Font((String)value,Font.PLAIN,20);
label.setFont(font);
return label;
}
}
的JavaDoc
GraphicsEnvironment.getAvailableFontFamilyNames()的JDoc部分状态
Returns an array containing the names of all font families in this
GraphicsEnvironmentlocalized for the default locale,as returned byLocale.getDefault()..See also:
