[news.eclipse.tools] Re: Wizard, WizardDialog, WizardPage

["Ted Stockwell" <_nospam_emorning@xxxxxxxxxxxx>]

The WizardDialog class is responsible for calling the Wizard.addPages
method.
After calling the Wizard.addPages method the WizardDialog class calls the
Wizard.createPageControls method which in turn calls the createControls
method on all your wizard pages.  The WizardDialog does this so that it can
properly resize itself to accommodate all your pages.
However, if you would like to defer the call to your WizardPages
createControls methods then you can override your Wizard's
createPageControls method so that it does nothing, like so...
    public void createPageControls(Composite pageContainer) { }
In this case the call to your WizardPage's createControls(...) method will
be deferred until the page must actually be displayed.

One drawback to doing this is that the WizardDialog may not be able to
properly resize itself to accommodate all your wizard pages until the pages
are displayed.
