Functions called by DigiGuide

There are just two functions in the marker JavaScript code that are directly called by DigiGuide.

function OnSetInitialDefaults()

As it's name implies; it gives the marker the first opportunity to set the defaults for markers created with it. You can alter any of the marker attributes but you only get one shot at it. Once it has been called (or not called) DG will never call it again.

function OnMenuShow()

This is called when the user requests a context menu. It's your opportunity to add commands to the menu.
