InfoBox extends the Google Maps JavaScript API V3 OverlayView class.

An InfoBox behaves like a google.maps.InfoWindow, but it supports several additional properties for advanced styling. An InfoBox can also be used as a map label.

An InfoBox also fires the same events as a google.maps.InfoWindow.

class InfoBoxOptions

This class represents the optional parameter passed to the InfoBox constructor. There is no constructor for this class. Instead, this class is instantiated as a javascript object literal.


Properties Type Description
boxClass string The name of the CSS class defining the styles for the InfoBox container. The default name is infoBox.
boxStyle Object An object literal whose properties define specific CSS style values to be applied to the InfoBox. Style values defined here override those that may be defined in the boxClass style sheet. If this property is changed after the InfoBox has been created, all previously set styles (except those defined in the style sheet) are removed from the InfoBox before the new style values are applied.
closeBoxMargin string The CSS margin style value for the close box. The default is "2px" (a 2-pixel margin on all sides).
closeBoxURL string The URL of the image representing the close box. Note: The default is the URL for Google's standard close box. Set this property to "" if no close box is required.
content string|Node The content of the InfoBox (plain text or an HTML DOM node).
disableAutoPan boolean Disable auto-pan on open (default is false).
enableEventPropagation boolean Propagate mousedown, click, dblclick, and contextmenu events in the InfoBox (default is false to mimic the behavior of a google.maps.InfoWindow). Set this property to true if the InfoBox is being used as a map label. iPhone note: This property setting has no effect. Events are always propagated for an InfoBox in the "mapPane" pane and they are not propagated for an InfoBox in the "floatPane" pane.
infoBoxClearance Size Minimum offset (in pixels) from the InfoBox to the map edge after an auto-pan.
isHidden boolean Hide the InfoBox on open (default is false).
maxWidth number The maximum width (in pixels) of the InfoBox. Set to 0 if no maximum.
pane string The pane where the InfoBox is to appear (default is "floatPane"). Set the pane to "mapPane" if the InfoBox is being used as a map label. Valid pane names are the property names for the google.maps.MapPanes object.
pixelOffset Size The offset (in pixels) from the top left corner of the InfoBox to the map pixel corresponding to position.
position LatLng The geographic location at which to display the InfoBox.
zIndex number The CSS z-index style value for the InfoBox. Note: This value overrides a zIndex setting specified in the boxStyle property.
