Request for member ‘pixelWidth’ in ‘this’, which is of non-class type ‘Tile* const’
From Cppsyntax
You can get the error
request for member ‘bar’ in ‘this’, which is of non-class type ‘Foo* const’
if you use this in a member function of an object.
In Java, 'this' is an instance; in C++ it is a pointer to an instance.
WRONG
class Foo
{
int getOne()
{
return 1;
}
int getTwo()
{
return this.getOne()+1; // incorrect use of this
}
};
RIGHT
class Foo
{
int getOne()
{
return 1;
}
int getTwo()
{
return this->getOne()+1; // incorrect use of this
}
};
ALSO RIGHT
class Foo
{
int getOne()
{
return 1;
}
int getTwo()
{
return getOne()+1; // incorrect use of this
}
};
