    • Method Detail

      • addPages

        void addPages()
        Adds any last-minute pages to this wizard.

        This method is called just before the wizard becomes visible, to give the wizard the opportunity to add any lazily created pages.

      • canFinish

        The result of this method is typically used by the wizard container to enable or disable the Finish button.

        Returns:

      • createPageControls

        void createPageControls​(Composite pageContainer)
        Creates this wizard's controls in the given parent control.

        The wizard container calls this method to create the controls for the wizard's pages before the wizard is opened. This allows the wizard to size correctly; otherwise a resize may occur when moving to a new page.

        pageContainer - the parent control
