[tcljava-user] tclblend java::bind with own event

[Klara W. <kl...@sp...>]

Hi,
I tried to use my own event with java::bind but it didn't work.
Has anyone tried this?
When I run(I'm on windows2000) the script on it's own it said "Error in
startup script" and referred to the java::bind line. When I run in wish, it
just won't work. I tell the java-class to invoke the event, but nothing
happens, I think the event is performed, but tcl won't react to it.
I tried the exact same thing with java.awt.ActionEvent and that worked. So
either tclblend won't work with you own events, or I wrote my event wrong
somehow...

Hi Klara.

I can't think of any reason why your own events would not work with the
java::bind command. Could you check to make sure that your class
is exposing events using the java::info command? Here is an example
of events exposed by a java.awt.Button from the java::bind man page:

http://tcl.activestate.com/man/java1.2.6/TclJava/JavaBindCmd.html

% java::info events $b
java.beans.PropertyChangeListener java.awt.event.ComponentListener
java.awt.event.MouseMotionListener java.awt.event.MouseListener
java.awt.event.HierarchyListener java.awt.event.KeyListener
java.awt.event.ActionListener java.awt.event.FocusListener
java.awt.event.HierarchyBoundsListener java.awt.event.InputMethodListener

If you can see the listener but you can't bind events to it, then could you
trim your example down to one .java file and a few Tcl commands and
post it to the list?

I was just about to cut and paste all my classes into one file when i
noticed that I had forgotten public in front of interface MyListener...
*big sigh*
Now it works.
java::info said MyListener, but I guess that just looks for
add/removeMyListener..
