c++ - Should the name of my classes begin with 'Q' in Qt?

Question

When I first started working with Qt, it was extremely annoying that every class has a name beginning with 'Q', but now I've got used to it.

I'm using Qt Creator, and it highlights code quite well.
However, it only highlights class names beginning with 'Q'. And it highlights everything beginning with 'Q' even if there is no such type.
It doesn't highlight custom class names.

That makes me wonder, should I also begin all my class names with 'Q'?
Or at least the reusable ones?
(I mean, those that I put in a class library, or reuse in another app.)

I've seen several places where they named their classes this way. Is it a good thing?

I found this page about Qt's naming conventions, but it doesn't deal with this question.

Also, I don't understand why Qt doesn't use namespaces.

EDIT:

Big thank you to everyone who shared his thoughts with me.

EDIT 2:

It seems that the newer versions of Qt Creator now also highlight the class names not beginning with 'Q'. Nice!

I can't see why you would want to enforce this on your own classes at all. Let Qt do what it wants to do with its class naming convention and you do your own.
