Thread: Accessing functions of a unique_ptr

Hi guys,

I might be doing this completely the wrong way but I'm trying to access functions contained by a unique_ptr.

Here's what I'm trying to do:

Code:

while(mp_renderManager->getWindow()->close()) {
...
}

Now I'm able to access getWindow() but, I cannot however get to close().

in my RenderWindow class it's as follows:

Code:

std::unique_ptr<sf::RenderWindow> mp_window;

...

const std::unique_ptr<sf::RenderWindow> const { return mp_renderWindow; }

How can I access the functions of sf::RendreWindow when it's wrapped in a unique_ptr?

If this isn't possible, can I do it with a shared_ptr or something?

Thanks.

Jamie.

Does getWindow return a pointer?

Assuming mp_window and mp_renderWindow are supposed to be the same and the last bit of code is the getWindow function with the name missing (you should read your question carefully to see that it actually makes sense!), then you should be returning a reference since you're not allowed to copy a unique_ptr.

yeah, I made a mistake, it's supposed to be:

Code:

const std::unique_ptr<sf::RenderWindow> getWindow() const { return mp_window; }

So, what's your actual error message from the compiler say?

So did changing it to this solve your problem or what?

Code:

const std::unique_ptr<sf::RenderWindow> & getWindow() const { return mp_window; }

Usually people tell us the error message instead of making a guessing game out of it.
