2 * @name InfoBox
3 * @version 1.1.13 [March 19, 2014]
4 * @author Gary Little (inspired by proof-of-concept code from Pamela Fox of Google)
5 * @copyright Copyright 2010 Gary Little [gary at luxcentral.com]
6 * @fileoverview InfoBox extends the Google Maps JavaScript API V3 <tt>OverlayView</tt> class.
7 *  <p>
8 *  An InfoBox behaves like a <tt>google.maps.InfoWindow</tt>, but it supports several
9 *  additional properties for advanced styling. An InfoBox can also be used as a map label.
10 *  <p>
11 *  An InfoBox also fires the same events as a <tt>google.maps.InfoWindow</tt>.

33 * @name InfoBoxOptions
34 * @class This class represents the optional parameter passed to the {@link InfoBox} constructor.
35 * @property {string|Node} content The content of the InfoBox (plain text or an HTML DOM node).
36 * @property {boolean} [disableAutoPan=false] Disable auto-pan on <tt>open</tt>.
37 * @property {number} maxWidth The maximum width (in pixels) of the InfoBox. Set to 0 if no maximum.
38 * @property {Size} pixelOffset The offset (in pixels) from the top left corner of the InfoBox
39 *  (or the bottom left corner if the <code>alignBottom</code> property is <code>true</code>)
40 *  to the map pixel corresponding to <tt>position</tt>.
41 * @property {LatLng} position The geographic location at which to display the InfoBox.
42 * @property {number} zIndex The CSS z-index style value for the InfoBox.
43 *  Note: This value overrides a zIndex setting specified in the <tt>boxStyle</tt> property.
44 * @property {string} [boxClass="infoBox"] The name of the CSS class defining the styles for the InfoBox container.
45 * @property {Object} [boxStyle] An object literal whose properties define specific CSS
46 *  style values to be applied to the InfoBox. Style values defined here override those that may
47 *  be defined in the <code>boxClass</code> style sheet. If this property is changed after the
48 *  InfoBox has been created, all previously set styles (except those defined in the style sheet)
49 *  are removed from the InfoBox before the new style values are applied.
50 * @property {string} closeBoxMargin The CSS margin style value for the close box.
51 *  The default is "2px" (a 2-pixel margin on all sides).
52 * @property {string} closeBoxURL The URL of the image representing the close box.
53 *  Note: The default is the URL for Google's standard close box.
54 *  Set this property to "" if no close box is required.
55 * @property {Size} infoBoxClearance Minimum offset (in pixels) from the InfoBox to the
56 *  map edge after an auto-pan.
57 * @property {boolean} [isHidden=false] Hide the InfoBox on <tt>open</tt>.
58 *  [Deprecated in favor of the <tt>visible</tt> property.]
59 * @property {boolean} [visible=true] Show the InfoBox on <tt>open</tt>.
60 * @property {boolean} alignBottom Align the bottom left corner of the InfoBox to the <code>position</code>
61 *  location (default is <tt>false</tt> which means that the top left corner of the InfoBox is aligned).
62 * @property {string} pane The pane where the InfoBox is to appear (default is "floatPane").
63 *  Set the pane to "mapPane" if the InfoBox is being used as a map label.
64 *  Valid pane names are the property names for the <tt>google.maps.MapPanes</tt> object.
65 * @property {boolean} enableEventPropagation Propagate mousedown, mousemove, mouseover, mouseout,
66 *  mouseup, click, dblclick, touchstart, touchend, touchmove, and contextmenu events in the InfoBox
67 *  (default is <tt>false</tt> to mimic the behavior of a <tt>google.maps.InfoWindow</tt>). Set
68 *  this property to <tt>true</tt> if the InfoBox is being used as a map label.
