Access the Global Preferences of Eclipse [message #330720]

Hi All,

I'm developing an plug-in for Eclipse and at some point of it I want to
read some peace of the Eclipse Preferences. In particular I want to know
if the user wants a external or internal browser.

On the other hand I wouldn't need to do this if there was a programmatic
way to open a internal browser in Eclipse in a new editor or view but side
by side with the editors. My big goal was to have a browser launched side
by side with editors but couldn't achieve this so I created my own view
and i nest the browser inside it.

Any help of advice would be appreciated.

You'll have to find the plugin that owns that particular preference and
investigate its preferences store and the right key to look up. Plug-in
Spy can help you in that investigation:

Ganyemde)

The Web Tools Project does this when you right-click on a JSP and choose
Run on server... so if you can find where in their code they are doing
that you might be able to adapt it to your needs. Perhaps asking about
that on the eclipse.webtools newsgroup would yield some guidance.

Hope this helps,
Eric

Thank you for the help Eric.

So on the browser preferences... I found the plug-in that contributes them:

<code>org.eclipse.ui.browser</code>

I also found the source of it's preference page:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.ui.brow ser/src/org/eclipse/ui/internal/browser/WebBrowserPreference .java?view=markup

I see that they have there this really good public method.
<code>public static int getBrowserChoice()</code>
but the class that provides this is internal... Is there a way for me to
call this method from my code? I thought may be not so i tried the
following code:
<code>
int b = PreferencesService.getDefault().getInt("org.eclipse.ui.browser ",
"browser-choice", -7, null);
System.out.println(b);
</code>
When i choose external browser b is 1.
When i choose internal browser b is -7.... A little strange.

I don't know what to do now... Is what I'm doing right? Is there a better
way?

Thanks Nikola
