Question

java Jlist 的字体怎么没法设置？ 代码如下，怎么没效果？

class MyCellRenderer extends JLabel implements ListCellRenderer {
// final static ImageIcon longIcon = new ImageIcon("long.gif");
// final static ImageIcon shortIcon = new ImageIcon("short.gif");

// This is the only method defined by ListCellRenderer.
// We just reconfigure the JLabel each time we're called.

public Component getListCellRendererComponent(
JList list, // the list
Object value, // value to display
int index, // cell index
boolean isSelected, // is the cell selected
boolean cellHasFocus) // does the cell have focus

{

String s = value.toString();

setText(s);

//this.setFont(new Font("华文行楷",1,12));
setFont(new Font("华文行楷",1,12));

// setIcon((s.length() > 10) ? longIcon : shortIcon);

if(cellHasFocus){

setForeground(Color.red);

}

if (isSelected) {
setBackground(list.getSelectionBackground());
setForeground(list.getSelectionForeground());
} else {
setBackground(list.getBackground());
setForeground(list.getForeground());
}

setEnabled(list.isEnabled());
setFont(list.getFont());
setOpaque(true);

return this;

}

我现在做一个界面代码，其中就用到了JList；但是就是不能自由设置JList的{"特瑞 ", "bbb" }; JList t = new JList(s); t.setVisibleRowCount

追问

我 那个 问题 我知道了，setFont(list.getFont());
又 给改回去了！！
