[Jython-users] swing in Jython

[syKim <re...@ne...>]

Hi  :)

I'm trying swing programming in jython 2.0

I made simple text editor with InternalFrame

however, when I executed it opens another applet window under appletviewer
or netscape..

(It works on it but, not well)

main applet window in appletviewer or netscape is just empty.

what's problem on it?

Source code :
----------------------------------------------------------------------------
------------------------
import java
from java.awt import *
from java.awt.event import *
from javax.swing import *
from javax.swing.text import *

class SmallEdit(JFrame):

        def exit(e) : java.lang.System.exit(0)
        frame=JFrame('test',visible=1,size=(400,300))
        frame.getContentPane().setLayout(BorderLayout())
        editor=JTextArea()
        editor.requestFocus()
        inner=JInternalFrame('newfile',1,1,1,1,visible=1)
        inner.setSize(200,150)
        scroll=JScrollPane(autoscrolls=1,preferredSize=(200,150))
        port=self.scroll.getViewport()
        port.add(editor)
        inner.getContentPane().add('Center',scroll)
        desktop=JDesktopPane(preferredSize=(400,300))
        desktop.add(inner)
        button = JButton('Exit',actionPerformed=exit)
        frame.getContentPane().add(desktop)
        frame.getContentPane().add('West',button)
        frame.pack()

You created a /new/ JFrame instead of using the frame the applet gives
you.

JFrame, JDialog, JWindow (and maybe one other widget) all have
heavyweight native peers.  If you create one, you get a new native
window.  Instead try using the frame the applet already has.  (I'm not
sure where to find it, but try the Applet class's documentation)

[Jython-users] distribution of Jython-based apps, jythonc, etc.

[William D. <wdd...@ma...>]

Hi,

I've been working on a project that I want to distribute as open source and,
now that I am about to the alpha stage, I am trying to determine how to do
that. I am sure that there is ample guidance at the Sun and Python/Jython
websites about the legal aspects, but I am a bit stymied at the technical
ones. The source (right now) is all Jython; my long-range plan is to port
most of the code to Java and just leave the highest-level stuff in Jython
and use Jython for a macro/scripting language for the app.

I have done most of the development on a Windoze 2000 laptop (I work on this
while I am commuting to work on a train) but, though I want the final
product to be as platform-independent as possible, my main user base will be
Mac users.

My first guess at the easiest way to distribute this code was to use jythonc
to build a single jar that would hold all the Jython classes. That way the
users would only have to install a jre and Swing. However, I have not had
any success in getting jythonc (I get a very long list of compiler errors)
to complete this task and the documentation for it seems to be useful more
as a reference for experienced users than a tutorial for new ones. It would
be helpful to me if someone would post a detailed how-to for the complete
task of using jythonc to prepare a jar suitable for distribution to users
that will not have Jython installed.

If I don't use jythonc, what other ways do you all find to work well? Can I
take the .class files built by Jython and use another tool (like
ClassWrangler on the Mac) to build a jar that I could distribute with
jython.jar?

Thanks!
Bill

Hmm,  when I tried jythonc I had no trouble at all.  I simply gave it
the --jar and --deep (or --all) options and it built a jar file
containing java bytecodes for my python source and the jython
interpreter bundled together.  Could you post the errors you are
getting?

AFAIK jythonc merely takes the .class files it outputs and the .class
files necessary from the jython.jar file and puts it into a new jar
file.  (Ok, a simplification since it first generates Java source and
also figures out dependencies)  If you want to do that by hand, the
'jar' part of the JDK should be able to handle it.  jar is run very
similarly to tar except it produces a .jar file instead of a .tar
file.

HTH,
