(

)

Return the OpenGL context tied to this drawable. If the context has not yet been initialized, then return nullptr.

void RE_OpenGLDrawable::doneCurrent

)

Clear this drawable's context as the current context. Do nothing if the drawable's context is not the current context.

static const char* RE_OpenGLDrawable::drawableSurfaceTag ( )

inlinestatic

Return the string tag used to identify whether a QWindow is used a drawable surface for Houdini.

Definition at line 92 of file RE_OpenGLDrawable.h.

const RE_Window* RE_OpenGLDrawable::getREWindow ( ) const

inline

Return the window that the drawable is currently assigned to.
