Hi, I'm trying to figure out who is owning the *_SCREEN object pointed to by EDA_DRAW_FRAME::m_currentScreen.
In EDA_DRAW_FRAME::~EDA_DRAW_FRAME(), the object pointed to is deleted, which suggests to me that the draw frame has some sort of ownership, however this will only delete the last object attached -- if SetScreen() is called, the old object is not deleted. What is the intended semantic here? Should the DRAW_FRAME take ownership, or not? As it is now, anyone calling SetScreen() must remember to GetScreen() first, so they can clean up if needed, which is somewhat counterintuitive for an interface. Simon
