public class InterruptDialog
extends javax.swing.JDialog
implements java.awt.event.ActionListener, PacketListener
This is an "interrupt computation" dialog similar to the one you see in the notebook front end when you select Kernel/Interrupt Evaluation. The dialog that appears has choices for aborting, quitting the kernel, etc., depending on what the kernel is doing at the time.

This class is a standard PacketListener, and you use it like any other. For example:

     ml.addPacketListener(new InterruptDialog(myParentFrame));
After this, whenever you interrupt a computation (by sending an MLINTERRUPTMESSAGE or, more commonly, by calling the KernelLink.interruptEvaluation() method), a modal dialog box will apppear with choices for how to proceed.

You must provide a Frame or Dialog object in the constructor. This will be the parent window of the modal interrupt dialog.

    • packetArrived

      public boolean packetArrived​(PacketArrivedEvent evt) throws MathLinkException
      Description copied from interface: PacketListener
      Called when a packet arrives.

      Your implementation can read some or all of the packet contents, or ignore it completely, without affecting the internal packet loop. In other words, you do not need to make sure that you fully read the contents.

      Return true in normal circumstances. Programmers with special knowledge of the internal workings of the packet loop can choose to return false to indicate that this packet should not be seen by any additional PacketListeners or J/Link's internal packet handling.

      Specified by:
      packetArrived in interface PacketListener
      Parameters:
      evt - the PacketArrivedEvent
      Returns:
      true
      Throws:
      MathLinkException
    • actionPerformed

      public void actionPerformed​(java.awt.event.ActionEvent evt)
      Specified by:
