Detailed Description

Arrows destined to be drawn on the map.

Created for the whiteboard system.

Member Typedef Documentation

typedef std::map<map_location, image::locator> arrow::arrow_symbols_map_t [protected]

Definition at line 102 of file arrow.hpp.

typedef std::string arrow::STYLE

The style is simply the name of a subdirectory under images/arrows, that holds an alternate copy of the arrow graphics.

If it doesn't exist or has missing images, you'll get "under construction" symbols instead of arrow graphics.
