Note: If you override this method to provide column support you will also need to override AbstractTextEditor.createVerticalRuler() to return a CompositeRuler.

Out of the box this class does not install this support and hence this implementation always returns null.

Overrides:
createColumnSupport in class AbstractTextEditor
Returns:
the column support or null if none

handlePreferenceStoreChanged

protected void handlePreferenceStoreChanged(
PropertyChangeEvent event)
Description copied from class: AbstractTextEditor
