enum initialization

[ad5xj]

I have been programming with Qt for some time now and I have come across a non-Qt code snippet that uses the following:

namespace MySpace {
class MyClass;
enum { SomeProperty = QTextFormat::UserProperty + 248 };
...
}

namespace MySpace {
class MyClass;
enum { SomeProperty = QTextFormat::UserProperty + 248 };
...
}

To copy to clipboard, switch view to plain text mode 

and is later reference by:

namespace MySpace {
MyClass::MyClass()
{
    myFunction(MySpace::SomePropery, param2);
...
}

namespace MySpace {
MyClass::MyClass()
{
    myFunction(MySpace::SomePropery, param2);
...
}

To copy to clipboard, switch view to plain text mode 

I am sure I should know what this is doing - but like a newbie ... I have no idea.

Can someone explain?

Environment:
Linux Mint 17.2
Qt Open Source 32 bit v5.5.1
