I learned some examples of RCP development, vogella.com-articles/EclipsePreferences/article.html, the article practice how to use eclipse preference, "To display the preference page you can use the standard Eclipse command org.eclipse.ui.window.preferences. Add this to your menu. It will show the preference dialog", Your means we can't use standard eclipse command in eclipse 4, we just create customizable command for this function in eclipse 4.
The section you are referencing is headlined with "Preference handling in Eclipse 3.x". So yes, this is different to Eclipse 4.
In Eclipse 4 there is no such standard command, and there is no such dialog. At least in plain Eclipse 4. If you implement a plugin for the Eclipse IDE you need to operate on the compatibility layer. But AFAIK then you need to implement your stuff still Eclipse 3.x based as it is not possible to mix Eclipse 3.x and Eclipse 4 development.
