[Qt-interest] QDialog is blank

[David Doria]

I am trying to make a simple example of QDialog. I tried this:
http://programmingexamples.net/index.php?title=Qt/Dialog but the
dialog that is opened does not have the buttons or label that I saw in
the Designer. I think it might be a problem with the Dialog()
constructor - would someone mind taking a quick look?

Also, I've seen examples that use ->exec() instead of ->show(), but
when I try that it says there is no such function.

Thanks,

David
