You can convert QBuffer to QString using buffer function of the QBuffer. Here is how you can do it.
QBuffer b;
b.open(QBuffer::ReadWrite);
b.write("http://amin-ahmadi.com");
QString str = b.buffer();
qDebug() << str; // "http://amin-ahmadi.com"
b.close();
You need to use a QRegExp to achieve this. “\s” means any white space character and “+” means any number of that pattern. So you can use the following line to find any number of consecutive white spaces and split you string:
line.split(QRegExp("\s+"))
This question comes up a lot and is sometimes very confusing but if you just pay attention for a few seconds you’ll get past this forever, I promise you.

The same as standard C String, for this also you can go through standard C++ as shown below:
Let’s say you have a QString, like this:
QString s = "www.amin-ahmadi.com";First convert it to std::wstring and then use its c_str method, like this:
s.toStdWString().c_str()
The best solution for this would be to go through standard C++ and it means this:
Let’s say you have a QString, like this:
QString s = "www.amin-ahmadi.com";First convert it to std::string and then use its c_str method, like this:
s.toStdString().c_str()Web developers are quite familiar with Base64 and its usage. To put it simply, whenever to want to store, transfer (send or receive) or do anything else with the contents of a binary file (in this example, an image file) you can use Base64 encoding to simplify things by converting unreadable binary contents to a readable string.
