- Test mouse.
- Mouse clicks go to the top GUI.
- The top GUI may pass them down recursively.
- A GUI may be marked as mouse-active, for dragging.
- Update top GUI.
- Update functions are called recursively.
- This can be used for animation for example.
- If there's time, draw top GUI.
- Draw functions only draw areas marked for redrawing.
- Marked areas are unmarked once they have been drawn.
- Draw functions are called recursively.
- If a child has moved:
- It will call its parent for the vacated areas.*
-
-The child will have been removed from the parent's list while
-it was drawn, so recursive cycles cannot occur.
