或许,你是在一种像功能一样的工具之后。 如果是,研究提供诸如“JLabel”等清单CellRenderer部件,并确定“JLabel”的工具。
E.G. of using HTML rendering in a tool tip.
import javax.swing.*;
class LabelWithHtmlTooltip {
public static void main(String[] args) {
Runnable r = new Runnable() {
public void run() {
String html = "<html><body>" +
"<h1>Header</h1>" +
"<img src= http://pscode.org/media/starzoom-thumb.gif " +
"width= 160 height= 120 >";
JLabel label = new JLabel("Point at me!");
label.setToolTipText(html);
JOptionPane.showMessageDialog(null, label);
}
};
SwingUtilities.invokeLater(r);
}
}
在这方面,我将努力执行:
添加一名MouseListener和MouseMotionListener给你的JList。 当用户进入名单上时,就开始等待某种拖延(第二段)。 当 mo改或拖拉时,重新开始等待拖延。 当摩擦离开前线时,穿透线。 利用这些听众来追踪模拟立场。
拖延一旦解决(因此,这应意味着 mo留在清单中,而不会全部拖延),那么就使用公共事业。 援引 稍后将显示信息箱。 你们可以利用JList的所在地ToIndex来确定哪一行是 mo。
