Preferences sharing across all workspaces - Handling programatically

To share preferences across all workspaces in eclipse, you need to save preferences via ConfigurationScope.

What is configuration scope ?

Preferences stored in this scope are shared by all workspaces that are launched using a particular configuration of Eclipse plug-ins. On a single-user installation, this serves to capture preferences that are common to all workspaces launched by that user. On a multi-user installation, these preferences are shared by all users of the configuration.

How to save ?

IEclipsePreferences store = ConfigurationScope.INSTANCE.getNode(MyUIPlugin.PLUGIN_ID);

if (store != null)

{

store.putBoolean(MyFLAG_PREF, true);

try

{

store.flush();

}

catch (BackingStoreException e)

{

//Log exception

}

}

How to retrieve the saved preference value?

boolean isSet = Platform.getPreferencesService().getBoolean(MyUIPlugin.PLUGIN_ID,

MyFLAG_PREF, false, new IScopeContext[] { ConfigurationScope.INSTANCE });
