Changeset 1595 for code/branches/hud/src/util

Timestamp:

Jun 12, 2008, 10:42:15 PM (16 years ago)

Author:

Message:

• removed conversion functions in String.h
• you can use convertToString and convertFromString from Convert.h as shortcuts
• added "true", "false", "on", "off", "yes" and "no" as boolean values to the Converter
• Conversion bool —> string newly gives "true" or "false"
• HUDOverlay can deal with the aspect ratio, e.g. circles stay circles when resizing
• the rest isn't yet finished: svn save

Files:

• Convert.h (modified) (4 diffs)
• String.h (modified) (1 diff)
