That states that:
"Subclasses must implement the createControl framework method to supply
the page's main control."
My question:
Shouldn't id be "Subclasses must implement the _createContents_
framework method to supply the page's main control."?
Because createControl is inherited from DialogPage and implements
buttons and decoration. The method then calls the abstract
createContents that people use to fill out the preference page with SWT
controls.
