Re: A short guide on how to use NetBeans to create GUI and then use this GUI from clojure available
Vlad, thanks for updating the guide. I've saved the new version. Tim, thanks for the ideas. I've tried both and both work well. It did get me thinking that it would be great to have a way to interrogate an open gui app from the command line, or perhaps, from a separate area in the app itself (say, a special debugging tab in the main window). Having a standard way to alter the app while it's running would be some kind of wonderful. If anyone has any ideas on that I'd love to hear them.

Indeed you can do all those things using a REPL.You can interactively do pretty much anything. You could even embed a REPL into your application with a socket back-door, connect to it and really have fun with your users.

Re: A short guide on how to use NetBeans to create GUI and then use this GUI from clojure available
Michael, Timothy, Thanks much to both of you. 2) The current directory (parent of gui2) is in the class-path -cp option when launching Clojure The problem was that I had used the gui directory in the classpath, rather than its parent. (The real problem is that I'm a Java noobie.) The frame opens now and I can cancel it correctly. However, when I click OK (using either the original app.clj or Timothy's version) I get: C:\Users\Mike\Documents\test-projectc:\clojure\clj.bat app.clj Exception in thread AWT-EventQueue-0 java.io.IOException: Stream closed at sun.nio.cs.StreamEncoder.ensureOpen(Unknown Source) at sun.nio.cs.StreamEncoder.write(Unknown Source) at sun.nio.cs.StreamEncoder.write(Unknown Source) at java.io.OutputStreamWriter.write(Unknown Source) at java.io.Writer.write(Unknown Source) at clojure.lang.RT.print(RT.java:1186) at clojure.pr__788.invoke(boot.clj:1516) at clojure.lang.AFn.applyToHelper(AFn.java:184) at clojure.lang.RestFn.applyTo(RestFn.java:137) at clojure.apply__135.doInvoke(boot.clj:364) at clojure.lang.RestFn.invoke(RestFn.java:428) at clojure.prn__799.doInvoke(boot.clj:1540) at clojure.lang.RestFn.applyTo(RestFn.java:142) at clojure.apply__135.doInvoke(boot.clj:364) at clojure.lang.RestFn.invoke(RestFn.java:428) at clojure.println__805.doInvoke(boot.clj:1556) at clojure.lang.RestFn.invoke(RestFn.java:413) at clojure.eval__2299$fn__2301.invoke(app.clj:12) at clojure.lang.Proxy__2305.actionPerformed(Unknown Source) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased (Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) The problem is in the println function, as it works fine when I comment them out. I assume this is some sort of problem sending text to the DOS/Vista command shell that doesn't happen under *nix. Also, no text appears in the command shell when I enter some into the boxes and click OK. This isn't critical to running the app, of course, though having print capability back to the command shell makes an excellent debugging tool. It seems clear it will be an issue for anyone on Windows, and for a broad range of apps. As this is well beyond my modest Java powers, any ideas would be appreciated.

Re: A short guide on how to use NetBeans to create GUI and then use this GUI from clojure available
C:\Users\Mike\Documents\test-projectc:\clojure\clj.bat app.clj Exception in thread AWT-EventQueue-0 java.io.IOException: Stream closed The reason you are seeing this is that stdout has closed when the main clj program reaches the end, but the Swing thread is still running. I remember having this problem with an older build of Clojure but it doesn't happen for me anymore, so either something changed or the .bat file launching the script affects this behavior (I'm running on XP). If you put (read) at the end of your .clj file it will keep stdout open (until you enter some text at the consol). Here is a version which avoids the issue altogether by using a Dialog instead of stdout: http://groups.google.com/group/clojure/web/app.clj Regards, Tim. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.

Re: A short guide on how to use NetBeans to create GUI and then use this GUI from clojure available
Hello Tim, Thanks for pointing the mistakes in code and the quote thing. Will be fixed in the next version of the guide... You can call main very easily: (MainFrame/main nil) however seeing the default implementation does not return the created object, you can't add the action listeners, so it isn't much use. I thought of using it as the start function to make the GUI visible (instead of .setVisible). Cheers for showing me how to call the function. http://groups.google.com/group/clojure/web/app.clj Options are good :-). Any objections on including your variant in the guide?

It can be called as above but I do not know if/how to call that after the MainFrame has being created (i.e calling it on resulting object).

So calling MainFrame.main() runs the static method, but you cannot do m = new MainFrame(); m.main(); The generated main creates a new instance of MainFrame and makes it visible. There is no way for you to provide the object to main or get the object from main without modifying the java code.

Hi Vlad, A very useful guide. PS: Comments welcome... Ok great, let me nitpick! :) The java class you posted doesn't compile (unless name is renamed person_name, and location renamed person_location). The quote symbol rendered is not copy+paste friendly. You can call main very easily: (MainFrame/main nil) however seeing the default implementation does not return the created object, you can't add the action listeners, so it isn't much use.
