Class holding a valid drawing context.
If you need to make OpenGL calls without having an active window (like in a thread), you can use an instance of this class to get a valid context.
Having a valid context is necessary for every OpenGL call.
Note that a context is only active in its current thread, if you create a new thread it will have no valid context by default.
To use a sf::Context instance, just construct it and let it live as long as you need a valid context. No explicit activation is needed, all it has to do is to exist. Its destructor will take care of deactivating and freeing all the attached resources.
The constructor creates and activates the context
The desctructor deactivates and destroys the context
|sf::Context::Context||(||const ContextSettings &||settings,|
Construct a in-memory context.
This constructor is for internal use, you don't need to bother with it.
|width||Back buffer width|
|height||Back buffer height|
Activate or deactivate explicitely the context.
|active||True to activate, false to deactivate|
