establishing signal-slot connections between widgets in the same form with QtDesigner

Hi!
I was going throw the example of "shape-changing dialog" in the "C++ GUI programming with Qt 4, Jasmin Blanchet, Mark Summerfield".
As the dialog is not "shape-changing" e created a simple one with 3 buttons:

• Button X
• Button Cancel
• Button Ok

I seted the enabled property of the "Button Ok" to false.
I wish that it becomes enable when i press "Button X".

I entered "signals/slots" and connected this way:
"Button X" signal clicked() to slot ???????

Showld't there be a "enabled" option?

Thanks

Yes, there is QWidget::setEnabled(bool). But notice that it takes a bool parameter, and button has signals with a bool parameter only if it's checkable. So you can either make "Button X" checkable or you have to do it in code within an intermediate slot.

I get the point.
Thanks
