This is a KInputDialog example, but QInputDialog is the same:

@re = Qt::RegExp.new( "^[\\d\\w][-,&/\\d\\s\\w]*")

brandValidator = Qt::RegExpValidator.new(@re, self)

item = KDE::InputDialog.getText("New #{@label.downcase}", \
                     "Enter new #{@label.downcase}", \
                     nil, \
                     true, \
                     self, \
                     "AddItem", \
                     brandValidator, \
                     nil )

I advise to buy Caleb Tennis' QtRuby book and "C++ GUI Programming  
with Qt3". The latter is C++, but you will need it if you want to  
develop anything serious with Qt without getting crazy. You won't need  
to know a lot of C++ to understand it. Caleb's book is a good start,  
but you need a lot more.

You can also hang around #qtruby at freenode. Richard Dale and I are  
usually there. Not that I know a lot about Qt, Ruby or QtRuby yet, but  
he is a genius. Really.
