Make --button1disabled change based on state of checkbox on the same dialog

[pukoc]

Hi, regarding --button1disabled, I want to use it in a way where on launch button 1 is disabled but then i have a checkbox i want the user to check on the same page, if that is checked dynamically enable it again so they can proceed.

Cheers,
Eugen
