C++ static window pointer

[AggrorJorn]

I am having a hard time creating a static pointer to a new window. I have the following:

 

//.h
public:
static Leadwerks::Window* window;

//cpp
Leadwerks::Window* window;
Test::Test()
{
//Create a window
Test::window = Leadwerks::Window::Create("test");

 

Is this not possible or am I am forgetting something here?

Can you post more / attach a sample project ?

 

Right now, im am wondering: why you declaring "window" two times (in *.h and *.cpp) ?

 

// Edit: (your "public:" irritated me )

 

Sorry my mistake, Rick is right you have to initialize the static variable and not just declare it because the static variable exists (or can exists) before your class does.

@Aggror as far as I know outside the class is where you have to assign it, not just declare it.

 

 

//cpp

Leadwerks::Window* Test::window = NULL;

Could you explain why it irritated you? Since it is static I figured it wouldn't really matter whether is was public or private.

Ah thanks. I actually had a working sample of this in a school project. I simply forgot the class 'Test::' before the static variable in the cpp. I actually don't have to set it NULL. It works perfect like this as well:

Leadwerks::Window* Test::window;

I didnt realized it is a class

Only in debug mode, try this in release mode and you will wonder what an uninitialized variable can do.
