实现系统托盘图标(不依赖于平台)
在网上看了很多实现系统托盘图标的帖子,但都大同小异:借用dll动态链接库,用JAVA JNI实现。
我想的是有没有用纯JAVA实现的系统图标?它应该不依赖于OS的,能在Windows下实现,在Linux下也可以运行实现的?!
对不起,只有这么点分了!有了可以再加。
------解决方案--------------------public class DesktopTray {
private static Desktop desktop;
private static SystemTray st;
private static PopupMenu pm;
public static void main(String[] args) {
if(Desktop.isDesktopSupported()){//判斷目前平台是否支援Desktop類
desktop = Desktop.getDesktop();
}
if(SystemTray.isSupported()){//判斷目前平台是否支援系統托盤
st = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage( "netbeans.png ");//定義托盤圖示的圖片
createPopupMenu();
TrayIcon ti = new TrayIcon(image, "Desktop Demo Tray ", pm);
try {
st.add(ti);
} catch (AWTException ex) {
ex.printStackTrace();
}
}
}
public static void sendMail(String mail){
if(desktop!=null && desktop.isSupported(Desktop.Action.MAIL)){
try {
desktop.mail(new URI(mail));
} catch (
IOException ex) {
ex.printStackTrace();
} catch (URISyntaxException ex) {
ex.printStackTrace();
}
}
}
public static void openBrowser(String url){

public static void edit(){
if(desktop!=null && desktop.isSupported(Desktop.Action.EDIT)){
try {
File txtFile = new File( "test.txt ");
if(!txtFile.exists()){
txtFile.createNewFile();
}
desktop.edit(txtFile);
} catch (IOException ex) {

}
}
}
public static void createPopupMenu(){
pm = new PopupMenu();
MenuItem openBrowser = new MenuItem( "Open My Blog ");
openBrowser.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
openBrowser( "http://blog.csdn.net/chinajash ");
}
});
MenuItem sendMail = new MenuItem( "Send Mail to me ");
sendMail.addActionListener(new ActionListener() {

}
});
MenuItem edit = new MenuItem( "Edit Text File ");
sendMail.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
edit();
}
});
MenuItem exitMenu = new MenuItem( "&Exit ");
exitMenu.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
pm.add(openBrowser);
pm.add(sendMail);
pm.add(edit);
pm.addSeparator();
pm.add(exitMenu);
}
}
------解决方案--------------------JDK6.0的系统托盘的雏形其实是个开源的JDIC,其实现原理就是不同的系统调用不同的JNI
不是象LZ那样想的,可以在任何平台上跑,所以也是分支持不支持的,LZ可以用JDK1.6或JDIC
