Localization of JFace MessageDialog [message #1580382]

Hi,

I'm trying to translate the buttons of a JFace MessageDialog. In English they are shown with "OK" and "Cancel". But in German they still are shown with "OK" and "Cancel".

I created the RAP Hello World example.

Added this to
BasicEntryPoint#createContents

MessageDialog.openConfirm(button.getShell(), "Title", "Buttons should be translated");

BasicApplication

public void configure(Application application ) {
    ...
    application.setOperationMode( OperationMode.SWT_COMPATIBILITY );

}

Copied the messages.properties from the org.eclipse.rap.jface... plugin to my plugin under src.org.eclipse.jface and renamed it to messages_de.properties. And did change the strings to

ok=OK
cancel=Abbrechen

build.properties looks like

bin.includes = META-INF/,\
               OSGI-INF/,\
               .,\
               src/org/eclipse/jface/messages_de.properties

PS:
RWT.getLocale() is de_DE

The Cancel Button still has the text "Cancel". What am i missing?

First of all, the Eclipse Babel project [1] provides community-managed language packs for various languages, and I invested some time to add the necessary German translations for RAP bundles. You can download the language packs from their website [2].

Depending on your build and runtime enviroment you'll need to update your target definition and make sure that the required fragments with the translations are part of your launch configuration.

Fragments? Bundles? I think here's the error in your setup. If I understand you correctly you were copying property files into your own bundle and translated them there. Unfortunately this is not how Eclipse searches for translations. You'll need to create a fragment that has the corresponding RAP bundle as host and put the language specific property files into this fragment.

But... as I wrote above... the easiest solution is to use the already available language packs from Babel.

Tanks a lot for your quick reply.

A Fragment was the key for the solution.

I created a fragment with org.eclipse.rap.jface as host and added the messages_de.properties there.

I also added this fragment in the launch configuration. And all is done.

Thanks again!

I will look at Babel the next days.

It's really worth looking at it because nearly all RAP strings are translated into German.

Have a nice weekend,

In my case it is exactly the opposite. My own strings are translated correctly in english, when i switch the language.
But the MessageDialog Buttons are always shown in german (my default system language).
Anyone an idea?

Are you using Babel?

Yes, I imported the package BabelLanguagePack-rt.rap-de_4.2.0.v20130724060447.
Is there a default package or something like this?

You might want try to import the rt.rap language pack into your target through the software site: http://download.eclipse.org/technology/babel/update-site/R0.12.1/luna.

You will have to include these features to your launcher.

I imported the features ending with nl_en_AA, nl_en_AU and nl_en_CA. But the buttons are still shown in german.
Is there a nl_en feature? I think thats whats missing. Because my .properties files are not used until i created the _en.properties files.

I set the locale using RWT.setLocale(Locale.ENGLISH). Maybe there is the mistake?

The only way changing the buttons text is the argument -nl en in the Run Configurations. I thought this would be dynamically, too.
So i solved it, but it is maybe not really fine.

By the way I understand it and made it work is that the -nl argument defines what is the default Locale of your Application. You don't need that. Once you added the *nl_* fragments from Babel to your launch config, you can change the language by changing the language of your browser. I believe nothing else is necessary. Unfortunately, I never tried to change the Locale on the run through a widget.
