WizardPage

Constructor
Assign ID to be able to access the page from other pages or from the Wizard. Initialize the page with setPageComplete(false).

	public FlatRatePage() {
		super("flatRate"); // this is the ID assignment
		setTitle("New Flat Rate");
		setDescription("Build a new flat rate");
		this.setPageComplete(false);

	}

Through the Wizard, the page can then be referenced as follows:

	public IWizardPage getNextPage() {
		if (this.flatRateButton.getSelection()) {
			return this.getWizard().getPage("flatRate");  // from the constructor shown above
		}
		if (this.weightBreakButton.getSelection()) {
			return this.getWizard().getPage("weightBreak1");
		}
	}

Default Focus
To assign focus when the WizardPage becomes visible, override the setVisible method (inherited from org.eclipse.jface.dialogs.DialogPage):

@Override
public void setVisible(boolean visible) {
	super.setVisible(visible);
	if(visible){
		this.weightBreakEditorComposite.forceFocus();
	}
}
