Detailed Description

OpenGL Context Store.

OpenGL will destroy its context when the screen is resized, or during other random times. When this happens you need to rebuild all the call lists, textures, shaders, etc. Since this is a simplified Engine, I only hold call lists, but in theory there could be more.

const

Check to see whether or not the specified list exists.

Parameters

handle

- [in] handle to the list

Returns

true if it does

Call_list_handle Dubious::Renderer::Open_gl_context_store::create_call_list

(

int

count

)

Create a number of new call lists.

Parameters

count

- [in] how many lists you want to make

Returns

a handle to the list. Use for subsequent calls

unsigned int Dubious::Renderer::Open_gl_context_store::get_call_list

(

Call_list_handle

handle

)

const

Get an OpenGL handle for the specified call list.

Will throw an exception if the specified list does not exist.

Parameters

handle

- [in] handle to the list

Returns

an int you can pass directly to OpenGL

Open_gl_context_store& Dubious::Renderer::Open_gl_context_store::operator= ( const Open_gl_context_store &  )

delete

void Dubious::Renderer::Open_gl_context_store::rebuild

(

)

Will rebuild the internal stores.

You must call this when the resolution changes, or when other context destroying actions happen
