Changeset 2816 for code/branches/gui/src/core

Timestamp:

Mar 21, 2009, 8:47:11 PM (16 years ago)

Author:

Message:

Upgrade number two for the InputManager: An InputState can have two new properties. You can tell it to always receive input, no matter what the input stack actually is. Secondly there is a 'transparent' option to be kind of invisible to the other states. I have found no use yet, but three more lines weren't a big deal
This change ultimately supersedes the need for a master InputState.
