How to load default preferences ? [message #308875]

Hi,

I want my plugin to load the default preferences given in the Preference
page. I have overridden initializeDefaultPluginPreferences() method in my
plugin class and have set the default values in the preference store. But
this API is not getting called and so my default values are not getting
loaded. If I call this API explicity, I can see the default values.

Am I missing something that calls the API mentioned which I might not have
overridden?
Here my default values are used to decorate the text in Package explorer.

One way is to use the extension point
"org.eclipse.core.runtime.preferences" to specify an initializer class
that extends AbstractPreferenceInitializer.

But that only runs when the user opens the "Prefs" dialog (Window -> Prefs -> MyPage), right?

What if one wants to ensure that the default values are set when the app starts so that client code
can use the preferences before the user goes and checks the values?

thanks,
Paul

Believe that it runs when the Plugin loads -- it is a core runtime
extension.

If use of the extension point is not desired for some reason, the
AbstractUIPlugin#start() method (overridden from the plugin activator
class) is available.

There's also a way to specify an initializer when you create your
preference. It's only loaded if something needs to read your preference.

Could you tell that way of specifying the initializer?
My problem got resolved when I used the extension
"org.eclipse.core.runtime.preferences"

It's part of org.eclipse.core.runtime.preferences :-)

In the PDE editor, which you are adding the extension select it and
"Open extension point description" That will take you to the page that
explains how to specify an initializer class and what you must subclass.

Rest assured - the preferences get initialized as soon as they are
accessed for the first time, so any time you might want to access them,
they are there...
