"new class" in GTK code....

[Christian Williamson]

Can anyone tell me right off why the keywords "new class" are used in
the following code, rather than just "new"? Why the word "class"? I know
it's a keyword, but I thought all you needed was new and delete.

Thanks.

Gtk::Label *label = Gtk::manage(new class Gtk::Label("Hello"));

I believe it is to specify precisely which type definition you're
referring to, i.e.:

class A {};
int main()
{
int A; // local variable 'A' hides the class name 'A'

class A a; // OK - got past the name hiding by using 'class'
}
