Pregunta
I have a C++ class which, in short, has a declaration which looks like this:
class Pico {
...
Document document; // Custom Document class
...
}
Later I call one of the public member functions of the Document
class:
this->document->enableEditing();
However, IntelliSense underlines this
and notes that "expression must have pointer type". What can I do to fix this?
Solución
You want
this->document.enableEditing();
The Document
member is not a pointer, therefore you need .
in place of ->
Otros consejos
document
is not a pointer, so you do not need the ->
operator:
this->document.enableEditing();
In fact, in this case it isn't even necessary to use this
explicitly. The following will do:
document.enableEditing();
