PDE: Preferences: default values not available [message #148504]

Hi!

myplugin.getPreferenceStore().getInt(Preferences.P_BLAH);

returns 0, i.e. the default value for an int.

This is because I did not change the default of P_BLAH which is 5000. So, if
I change the value of P_BLAH on the preference page the above call will
return 5000. Or: If I open the preference page prior to the above call it
will also return 5000.

Well, how am I going to do this correctly?

Thanks
Timo

If I understand what you are trying to do shouldn't you be using
IPreferenceStrore.getDefaultInt(Preferences.P_BLAH)?

This returns the default value of P_BLAH, doesn't it?

Of course I want to get the value the user entered. But if the user didn't
change it I want the dafault value, of course...

Sounds like you want to set the default value for your preference.
IPreferenceStore.setDefault(Preferences.P_BLAH, int)

?? No.

I want to get it. The default values are automatically set when the
preference page is once opened:

public Preferences() {
super(GRID);
setPreferenceStore(Plugin.getDefault().getPreferenceStore()) ;
setDescription("A demonstration of a preference page implementation");
initializeDefaults();
}

private void initializeDefaults() {
IPreferenceStore store = getPreferenceStore();
store.setDefault(P_BLAH, 5000);

}

But initializeDefaults() is only called when I open the preferenc page,
right? So, I don't know how eclipse does handle this internally or how it
does make changes to the preferences persistent, but the sense of a
preference page is to change the values, not to be called each time I want
to know them in order to use them...

I just need the value of P_BLAH in order for the plugin to work.

You need to move your initialization out of being tied to opening the
preference page.

We initialize our preferences (as all plugins should) using
AbstractUIPlugin.initializeDefaultPreferences(IPreferenceSto re) or
Plugin.initializeDefaultPluginPreferences depending on which type hierarchy
your plugin is involved with.

public Plugin(IPluginDescriptor descriptor)
{
super(descriptor);
plugin = this;
// neither this
initializeDefaultPluginPreferences();
// nor that
initializeDefaultPreferences(getPreferenceStore());
// does help :-(

You do not need to call these methods...part of the plugin lifecycle.
What does your implementation of these methods look like?

Now I'm completely confused :-) You mean, I need to implement
initializeDefaultPluginPreferences() myself?? And what shall I do within
it? I canno call the initialize method of the Preference class...

Can you post a simple example snippet?

Thanks.

It's somewhat strange code that's being generated by eclipse' wizard.

And how besides newbies does use wizards??

Anyway...

Here's a snippet. In your plugin class:

protected void initializeDefaultPreferences(IPreferenceStore store) {
PreferenceConverter.setDefault(store, Constants.ID_COMMENT,
Constants.COMMENT_RGB);
//...
store.setDefault(Constants.ID_TAB_WIDTH, 2);
}
