Customizing WizardNewFileCreationPage and WizardNewFolderMainPage: changing the default tree

We have created two custom wizard pages that extend from WizardNewFileCreationPage and WizardNewFolderMainPage. But we need to modify the default tree selection dialog (we need to show only a subset of the current tree elements). How can we do it ? I've found that attribute resourceGroup can't be modified. Creating a new class frow scratch is the only way?.

Plea开发者_开发技巧se, help. Thanks.

You have correctly found out that you cannot modify the resourceGroup as it is a private member of WizardNewFileCreationPage and WizardNewFolderMainPage. Because of its accessibility you can't even override public void createControl(Composite parent).

As far as I know there is no extension point to alter this behavior. Unfortunately you have to rewrite/create the whole thing.
