ArcMap add-ins JOptionPane

[LeoDonahue]

ArcMap 10.0 SP2
ArcObjects Java SDK SP2
Eclipse Helios 3.6.2
Java sdk 1.6.0_24

Following this example: http://help.arcgis.com/en/sdk/10.0/java_ao_adf/conceptualhelp/engine/0001/00010000041v000000.htm

I'm finding that using JOptionPane.showMessageDialog's do not always execute right away when you click a tool and sometimes the message dialog opens up behind ArcMap.  And don't click on anything else until you've dismissed the dialog or ArcMap hangs.

Anyone using Java add-ins?  If so, what are you using for notifying the client of certain actions?  JOptionPane messages?

I think we have to use SwingUtilities.invokelater in this type of situations. An example code is as below :-

public void mousePressed(MouseEvent mouseEvent) {

     try {

          // your other code

          SwingUtilities.invokeLater(new Runnable() {

          @Override

          public void run() {

          try {

               JOptionPane.showMessageDialog(null, message2, "Map Coordinates from Screen Coordinates", JOptionPane.INFORMATION_MESSAGE); 

               JOptionPane.showMessageDialog(null, message3, "Screen Coordinates from Map Coordi

          } catch (Exception ex) {}

          }

     });

     } catch (Exception e) {

          e.printStackTrace();

     }

}

Okay, this fixed the problem of ArcMap stalling if the MXD window is clicked while the JOptionPane is visible. But what about making sure that the JOptionPane stays in front of the current ArcMap Session/MXD?

Thank you so much for the help!
