Detailed Description

Helper class to make the shared GL context current.

Example:

class MyTexture {
public:
    MyTexture() : _textureId(0) {
        // allocate from the shared context pool.
        GlfSharedGLContextScopeHolder sharedContextScopeHolder;
        glGenTextures(1, &_textureId);
    }
 
    ~MyTexture() {
        // delete from the shared context pool.
        GlfSharedGLContextScopeHolder sharedContextScopeHolder;
        glDeleteTextures(1, &_texureId);
        _textureId = 0;
    }
 
    // The caller is responsible for making sure that a suitable
    // GL context is current before calling other methods.
 
    void Bind() {
        glBindTexture(GL_TEXTURE_2D, _textureId);
    }
 
    void Unbind() {
        glBindTexture(GL_TEXTURE_2D, 0);
    }
 
    ...
 
private:
    GLuint _textureId;
 
};
