Java: How to display a multi-line ToolTip with AWT?
I wrote an application and now I'm making a tray-icon. Now I want to set a multi开发者_Go百科-line tooltiptext to the tray-icon. But I don't know how. I know how to do this with Swing:
component.setToolTipText("<html>Line 1<br>Line2</html>");
But this doesn't work with AWT. Also serarating lines by \n doesn't work.
I'm running on linux:
Ubuntu 10.04
Kernel Linux 2.6.32-22-generic
GNOME 2.30.0
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)
OpenJDK Server VM (build 14.0-b16, mixed mode)
Any help would be very appreciated.
ThanksThe following code produced a perfectly fine multi line tooltip for me:
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
public class AWTScratch {
public static void main(String[] args) {
BufferedImage im = new BufferedImage(32, 32, BufferedImage.TYPE_INT_RGB);
TrayIcon ti = new TrayIcon(im, "Multiline\nmulti");
ti.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
ti.setImageAutoSize(true);
if (SystemTray.isSupported()){
SystemTray st=SystemTray.getSystemTray();
try {
st.add(ti);
} catch (AWTException e1) {
e1.printStackTrace();
}
}
}
}
Maybe its a platform issue. Could you give us your OS and jvm version? Seems to be a bug, see inside suns bug database.
JToolTip derives from JComponent, but you can simulate the effect yourself using Graphics-only methods, as shown in the AlphaView class of this example.
