Class: Map

Map

Google maps drawing class, provides tools for drawing over a google map canvas, and export drawn data.

This class handles the drawing tools used to draw over a google map and allows data exportation.

The map manages also some controllers

  • clear map controller
  • export map controller
  • geocoder text field controller
  • tips controller

Moreover every drawing tool has its own controller, which may be specifically set or used in its default form.

Each map controller may be specified as custom, may be removed by setting the related option to null or used in its default form.

Once instantiated the class and set the tools by options or instantiating direclty the drawing tool classes and adding them to the map, see Map#addTool, call the render method in order to render the widget.
It is possible to continue configuring the widget adding or removing tools and customize the google map instance which is returned by the Map#gmap method.

When defining specific map controllers, be sure to make them handle the proper map methods.

Very important: be sure to load the google maps library yourself in the head of the document!
