# Info window

Info window displays content in a floating window above the map. The info window looks a little like a comic-book word
balloon. It has a content area and a tapered stem, where the tip of the stem is at a specified location on the map.

## Build your info window

### By configuration file

By default, the bundle doesn't need any configuration. Most of the service have a default configuration which allows
you to use the given objects like they are. The ``ivory_google_map.info_window`` service is. The configuration
describes below is this default configuration.

```yaml
# app/config/config.yml

ivory_google_map:
    info_window:
        # Your own marker class
        class: "My\Fucking\InfoWindow"

        # Your own info window helper class
        helper_class: "My\Fucking\InfoWindowHelper"

        # Prefix used for the generation of the info window javascript variable
        prefix_javascript_variable: "info_window_"

        # Poisition of the info window
        # It is used if the info window is directly added to the map
        # If you add an info window to a marker, it will not be used
        position:
            latitude: 0
            longitude: 0
            no_wrap: true

        # Info window pixel offset
        # By default, there is no pixel offset
        pixel_offset:
            width: 1.1
            height: 2.1
            width_unit: "px"
            height_unit: "pt"

        # Info window content
        content: "<p>Default content</p>"

        # Info window default open state
        # TRUE if the info window is opened else FALSE
        open: false

        # This flag is only used if you link an info window to a marker
        # If it is enabled, an event will be generated for allowing you to open the info window when you trigger
        # the event configured below on the linked marker
        auto_open: true

        # Info window open event
        # Available open event : click, dblclick, mouseup, mousedown, mouseover, mouseout
        open_event: "click"

        # If it is enabled, the info window will be closed each time an info window configurated with the auto
        # open flag is opened.
        auto_close: false

        # Custom info window options
        # By default, there is no options
        options:
            disableAutoPan: true
            zIndex: 10
