Validating input in a WizardPage

Does anyone have a simple example of validating the input for a text
field
in a org.eclipse.jface.wizard.WizardPage? (To prevent the user from
going to the next page)

You may want to take a look at WizardPage#canFlipToNextPage():


/**
* The <code>WizardPage</code> implementation of this
<code>IWizardPage</code>
* method returns <code>true</code> if this page is complete
(<code>isPageComplete</code>)
* and there is a next page to flip to. Subclasses may override
(extend or reimplement).
*
* @see #getNextPage
* @see #isPageComplete()
*/
public boolean canFlipToNextPage() {
return isPageComplete() && getNextPage() != null;
}

Thank you!

I did 2 things.

In the example, the author has the WizardPage implement Listener.
I use handleEvent() to display Messages to the user
via setMessage() and setErrorMessage(). Also in handleEvent(), I call

getWizard().getContainer().updateButtons()

I am using canFlipToNextPage() to validate the page in my 1st 2 wizard pages. In my last page, canFlipToNextPage() should be false because there is not a next page.
