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

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...

?? 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.

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

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?

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);
}
