Detailed Description

Displayable subclass for creating geometric representations of molecules.

Member Enumeration Documentation

enum DrawMolItem::RegenChoices

Keep track of whether and why we have to regenerate rendering lists In particular, MOL_REGEN means molecular data has changed, whereas if all we did was change from one timestep to another, and nothing in the timestep has changed, then the update_ts flag is changed instead. The idea is that when we implement cached geometry for multiple frames, or a draw all frames option, we don't want to recreate the geometry unnecessarily.

Enumeration values:

NO_REGEN

MOL_REGEN
