Question

I’m very new to C++ and Qt, but I’m very good at C#/Java.

The point is I like cross-platform, but I’m confuse with Qt. Isn’t std::vector already cross-platform, doesn’t Qt provide an equivalent to a non-crossplatform thing?

Also how are File and QFile different?

A link would be nice, thanks 🙂

Answer 1

This article loooks good. It compares Qt Template Library with Standard Template Library:

• QTL vs STL

Hope, you’ll find it interesting seeing all the differences listed there in the article.

EDIT:

Here is what I find interesting:

My opinion is that the biggest
advantage of the QTL is that it has
the same implementation (including
binary compatibility) on all OSes
supported by Qt. Some STL
implementations might be below par
when it comes to performance or they
might be missing functionality. Some
platforms don’t even have an STL! On
the other hand, the STL is more
customizable and is available in its
entirety in header files… Like I said,
there is no clear winner.

Like he said, no clear winner. But still reading the article makes lots of things clear. Its better to know the difference than going for one, without knowing the other.
