Class UnsupportedJDetachCallCmd

java.lang.Object
  tcl.pkg.java.UnsupportedJDetachCallCmd

All Implemented Interfaces:

Runnable, Command

public class UnsupportedJDetachCallCmd
extends Object
implements Command, Runnable

This command is the only means to safely call a blocking Java method like a modal AWT dialog box. If you used java::call directly the entire application would hang because the AWT blocks the calling thread in an AWT modal dialos show() method. You would use this command in place of the java::call method or a java instance method. It will invoke a static or instance Java method using another thread so that the calling thread will not block. This command is unsupported and undocumented so you should only need to use it if you run into this problem.
