Changeset 2814 for code/branches/gui/src/core/input/InputManager.cc

Timestamp:

Mar 21, 2009, 5:30:16 PM (16 years ago)

Message:

InputManager upgrade number one: InputState priorities are managed automatically. However you can still use the enum in InputManager.h and get yourself a high priority.
High priorities are only to be used for special cases like calibrator, console or detector.
All other states are simply pushed onto the normal stack.
