Re: Disable "Finish" button in wizardpage

["Bob Foster" <bob@xxxxxxxxxx>]

I believe isPageComplete() will disable both the Next and Finish buttons.
What he wants to do is disable only Finish until the last page. Which I
think he can do by overriding canFinish() on preceding pages and returning
false. I think by "does absolutely nothing" he means the result of
canFinish() has no effect on the Finish button. To which I would echo
Christopher Elke. Let's see the code.
