GUI from newLISP.dll

HPW · Post by **HPW** » Sat Jun 09, 2007 6:38 am

When I try a:

(load "c:/Programme/newlisp/widgets-demo.lsp")

from newLISP.DLL

I get a console window with title: C:\Windows\system32\java.exe

server listening on 47011
server accepted from 0.0.0.0
server connecting to 0.0.0.0:47012
server connected

and the GUI shows up as expected.
But when I close the Java-GUI it also close the main-calling process.

Questions:

Can I launch the GUI without the visible java-console window?

Can I avoid the complete closing, so that newLISP.dll simply returns from the call to the calling app?
(Maybe (gs:listen) should get a parameter if complete closing is wanted.)

try one of the methods shown here: http://newlisp.org/index.cgi?page=Code_Snippets. Pjot is also distributing an app to start a Windows app, w/o the shell windows.

Can I avoid the complete closing

I will add a parameter to to gs:listen suppress the default closing behaviour.

This neobook script allow me to start java without the console window:
(I remove the similar start code gs:init)

Code: Select all

Run "java" "-jar [#34]C:\\Programme/newlisp/guiserver.jar[#34] 47011" "Hidden" "" ""

I will add a parameter to to gs:listen suppress the default closing behaviour.

Thanks, that will help to use it in this situation.
Of cource this can be used for kind of modal sub dialogs, because the newLISP call will not return until the GUI is closed.

Anyway, another powerfull option to use the new GUI stuff!
Keep it getting better!

Don't remove anything in gs:init (not sure if I understood you well).

There are already two methods existent to start a guiserver application:

(1) start the newLISP code and it will call gs:init which starts the guiserver.jar. This method in described in the modules helpfile.

Code: Select all

newlisp mypapp.lsp
; on Mac OS X, Unix
./myapp.lsp

(2) start guiserver.jar with Java and supply portnummber and newLISP code as a parameter:

Code: Select all

Java -jar c:\Program Files\newisp\guiserver.jar 47011 c:\home\myapp.lsp

The second method is best for packageing guiserver apps. On windows desktop an icon-link can be configured this way (similar to the existing Win32 icon for newLISP-tk)

On MacOS X the /Developer/Applications/Java Tools/Jar Bundder.app and the /Applications/Utilities/Disk Utility.app can be used to packaged and distributed a Guiserver application with Icon and located in the Applications folder.

One of the next development releases will have installers which install applictions icons on both platforms this way.

When I try 2 then I get:

Don't remove anything in gs:init (not sure if I understood you well).

I do it because I start the GUIserver hidden from my main neobook app, and then I load the widgets-demo by the newLISP.dll and there I will avoid a second java start with the console window.

I think you mean it this way:

Code: Select all

Java -jar c:\Programme\newlisp\guiserver.jar 47011 "c:\Programme\newlisp\newlisp.exe widgets-demo.lsp"

That works for as it start the GUI-Server and newLISP.EXE

But since I was using the DLL it would not work for me.
But it would be no problem to adapt guiserver.lsp for that.
Or you add another parameter for (gs:init) to disable the java start.
