Class Diagra of a C++/Qt4 GUI

[graciano]

Hi

I am learning Qt and made the option of using C++ for the task.
I wrote this small Dialog that i share in this link: [ http://www.box.net/shared/ljcs6moy6m ]

It is workink ok but then i decided to use Umbrello UML Modeller, loaded the code and make the Class Diagrama for me.

Can anyone arroud here take a look at the diagram and comment it for me?

Where to put the Ui namespace in the diagram?

Any help apreciated.

Thanks

PS: Sorry if it sounds a little offtopic and Meanwhile e think i will search for a QT specific forum.
