How to readout value from PreferenceStore [message #459271]

Hello all,

what's the common way to get the values of my workspace preference store?
I tried it like this:

IPreferenceStore store = Activator.getDefault().getPreferenceStore();
String string = store.getString("P_PATH");
System.out.println(string);

But this meant to be not correct, because I allways get an empty string.
May I dind't understand the way how to use the preference store?

Thx
Florian

No problems with that code, that I can see, so it must be that you have never *set* a value for the
key "P_PATH" (btw, Eclipse convention seems to be to use fully-qualified keys, like this
"de.spamfighter.wendland.P_PATH").

To set a value, call like this:

<code>store.setDefault(key, def_value); </code>

and also probably (if you want a value that can be varied by the user) like this:

<code>store.setValue(key, new_value); </code>

HTH,
Paul

I found the problem.
In fact, I tried to get like this

String string = store.getString("P_PATH");

but i had to do it like this.

String string = store.getString(PreferenceConstants.P_PATH);

Thanks :)
