List of all members.

Detailed Description

This is the base object for all map areas. It defines some standard interface to access the geometrical properties of the areas and describes the area itsef: {itemize} url# If the optional URL# is specified, the map area will also work as a hyperlink meaning that if you click it with your mouse pointer, the browser will be advised to load the page referenced by the URL#. target# Defines where the specified URL# should be loaded comment# This is a string displayed in a status line or in a popup window when the mouse pointer moves over the hyperlink area border_type#, border_color# and border_width# describes how the area border should be drawn area_color# describes how the area should be highlighted. {itemize}

The map areas can be displayed using two different techniques, which can be combined together: {itemize} Visible border. The border of a map area can be drawn in several different ways (like XOR_BORDER# or SHADOW_IN_BORDER#). It can be made always visible, or appearing only when the mouse pointer moves over the map area. Highlighted contents. Contents of rectangular map areas can also be highlighted with some given color. {itemize}
