TrayIcon: AWT or Swing
Greetings,
I played a bit with the SystemTray and the TrayIcon this morning and I
noticed something strange. Have a look at an early document that
describes this new feature:
http://java.sun.com/developer/technicalArticles/J2SE/Desktop/javase6/systemtray/
... and have a close look at those MenuItems: they're definitely Swing
JMenuItems (AWT MenuItems can't display Icons nor Images), but
when I read the API for the TrayIcon, it only manages a PopupMenu
which is an AWT component and can't handle JMenuItems.
IOW that entire tray facility is AWT based. Or am I missing something?
kind regards,
Jos

Sad but true.
There are some ways to show JPopupMenu in tray:
1) using org.jdesktop.jdic.tray.TrayIcon
2) http://jeans.studentenweb.org/java/trayicon/trayicon.html
3) http://systray.sourceforge.net
4) my ;-)
class JTrayIcon extends TrayIcon {
static AWTEventListener globalEventListener = null;
private JPopupMenu popupMenu = null;
public JTrayIcon(ImageIcon icon, String hint, JPopupMenu apopupMenu) {
super(icon.getImage(), hint);
initPopupMenu();
setPopupMenu(apopupMenu);
}
private Window getParentWindow(Container c) {
while (c != null) {
c = c.getParent();
if (c instanceof Window)
return (Window) c;
}
return null;
}
private void initPopupMenu() {
if (globalEventListener == null) {
globalEventListener = new AWTEventListener() {
public void eventDispatched(AWTEvent event) {
if (event.getSource() instanceof TrayIcon) {}
event.setSource(null); // needs to make happy BasicPopupMenuIU's AWTEventListener
}
};
Toolkit.getDefaultToolkit().addAWTEventListener(globalEventListener,
AWTEvent.MOUSE_EVENT_MASK);
}
addMouseListener(new MouseListener() {
public void mouseClicked(MouseEvent e) {
e.setSource(null);
if (popupMenu == null)
return;
switch (e.getButton()) {
case MouseEvent.BUTTON1:
if (e.getClickCount() > 1) {
Component c = popupMenu.getComponent(0);
if (c instanceof AbstractButton)
((AbstractButton)c).doClick();
}
break;
case MouseEvent.BUTTON3:
popupMenu.show(null, e.getX(), e.getY());
Window w = getParentWindow(popupMenu);
w.setAlwaysOnTop(true);
}
}
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mouseEntered(MouseEvent e) {}
});
}
public void setPopupMenu(JPopupMenu apopupMenu) {
popupMenu = apopupMenu;
}
}

Am not! I've hardly been around here the last couple of days (too busy).
First of all @vk(64K-1): thank you for your reply. For the moment I just
don't use Sun's crappy implementation of that system tray; I'll have a
look at your links and suggestions; thank you very much. My plans were
to just wait a bit 'till Sun comes up with something decent. Their current
implementation is just too limited (just AWT, no Swing, that's a nono)
and I've put any system tray usage quite low on my TODO list.
Second, @kelvarnson: :-P
kind regards,
Jos ;-)

Fair enough. It's just that I noticed the thread mysteriously creeping to the top of the heap about 3 or 4 times yesterday* without any new replies, and then again today. Perhaps vk was re-re-re-editing his post.
* - almost spelled this as "yeasterday", which begs the question: could this word be used legitimately next Monday?

't wasn't me Your Honour; 't must've been vk: he was posting all that
code; I didn't do nothin' squire!

It could, but it's already officially named "Happy Hangover Day!"
kind regards,
Jos ;-)
