Linden Lab Official:Map API Reference
Bounds
Represents the bounds for a 2D coordinate space. See the guide for more.
Constructor
Bounds ( xMin, xMax, yMin, yMax)
Properties
| Property | Default | Description |
|---|---|---|
| xMin | Zero | Minimum x coordinate of the bounding window. |
| xMax | Zero | Maximum x coordinate of the bounding window. |
| yMin | Zero | Minimum y coordinate of the bounding window. |
| yMax | Zero | Maximum y coordinate of the bounding window. |
NOTE: The default values are applied if any of the properties is not specified in the constructor call.
Icon
Represents an icon to used as a marker.
Constructor
Creates a new icon to be used on the map. The optional second parameter specifies a shadow image. See the guide for more. shadowImage defaults to null.
Img
Represents an image to be used as an icon.
Constructor
Img ( String imageSource, int width, int height, Boolean hasAlphaChannel )
Creates a new image to be used on the map. The optional fourth parameter is for specifying whether you are using a 24-bit PNG image with alpha channel transparency. See the guide for more. hasAlphaChannel defaults to false.
MapWindow
This class represents a window placed over the map.
Constructor
MapWindow ( String windowText, options )
Creates a new map window. The given text will be what is contained in the window. Note, HTML can be used but quotes must be escaped correctly otherwise javascript errors will occur.
The second optional argument is a hash of window options, as described in the following table.
| Property | Default | Description |
|---|---|---|
| alwaysOnTop | false | Whether window is always displayed on top of other windows. |
| noEffect | false | Whether window appears with fade-in and fade-out effect. |
| closeOnMove | false | Whether window is closed when user drags the map. |
| bringToTop | false | Whether window is brought to the top when user clicks other windows. |
| width | 252 | Width of the window in pixels. |
| height | 236 | Height of the window in pixels. |
| padding | 10 | Padding of the window in pixels. |
Marker
Represents a marker to be added on the map.
Constructor
Marker ( Array icons, XYPoint coordinate, MarkerOptions markerOptions )
Creates a new marker to be placed on the map at given coordinate. The first parameter is an array of icons of length 6. Each icon in the array corresponds to a zoom level, icons[0] being the icon used at the close zoom (level 0).
The optional markerOptions argument is a MarkerOptions object that defaults to null.
MarkerOptions
Properties
| Property | Default | Description |
|---|---|---|
| centerOnClick | false | centers the map on the marker when clicked. |
| clickHandler | null | sets a click handler. |
| onMouseOverHandler | null | sets a handler that gets executed during an onmouseover event. |
| onMouseOutHandler | null | sets a handler that gets executed during an onmouseout event. |
| autopanOnClick | true | the map will automatically pan the map if part of the associated MapWindow would have been clipped by an edge of the map when it was opened. |
| autopanPadding | 45 | this number represents how close the window needs to be to an edge of the map for autopan to trigger. |
| verticalAlign | "middle" | also can be set to "top" and "bottom". This specifies how the marker is vertically aligned. |
| horizontalAlign | "center" | also can be set as "left" or "right". This specifies how the marker is horizontally aligned. |
| zLayer | 0 | Specifies the layer the marker will render on. For example, if a marker having zLayer = 1 and another marker having zLayer = 0 overlap, the marker with zLayer = 1 will be on top. |
The clickHandler, onMouseOverHandler, and onMouseOutHandler options specify an optional functions that get called when their respective events occur. See the guide for more.
SLMap
This class represents the map.
Constructor
SLMap ( HTMLElement container, SLMapOptions options )
Creates the map. The options argument defaults to null.
Methods
| Method | Return Value | Description |
|---|---|---|
|
addMapWindow( MapWindow mapWindow, XYPoint coord ) |
None | Adds a MapWindow to the map at specified coordinate. |
|
addMarker( Marker marker, MapWindow mapWindow ) |
None | Adds a marker. If the optional mapWindow argument is null, then clicking on the marker will not open a window. |
|
clickMarker( Marker marker) |
None | Simulates a clicking a marker. Will recenter the pan if its not currently in the viewport of the map. |
|
disableDragging() |
None | Disables all dragging on the map. Note: panning controls will still work. |
|
enableDragging() |
None | Re-enables dragging on the map if it was disabled. |
|
enterAndZoomAtSLCoord( XYPoint coordinate, int zoom) |
None | Centers and zooms the map to the specified location. |
|
getCurrentZoomLevel() |
None | Gets the current zoom level (1-6). See about zoom levels. |
|
getMapCenter() |
XYPoint | Returns the current map center. See about coordinates. |
|
getViewportBounds() |
Bounds | Gets the viewport bounds. See about coordinates. |
|
panDown() |
None | Pans the map to the down by half its width. |
|
panLeft() |
None | Pans the map to the left by 1/2 its width. |
|
panOrRecenterToSLCoord( XYPoint coord, Boolean recenter ) |
None | Pans the map to the given coordinate if it is currently in the viewport (in the user's view). Otherwise, recenters the map to the given coordinate. The optional recenter argument specifies whether to center the given coordinate even it if is currently in the viewport. Its default value is false. |
|
panRight() |
None | Pans the map to the right by 1/2 its width. |
|
panUp() |
None | Pans the map to the up by 1/2 its width. |
|
removeAllMarkers() |
None | Removes all markers. |
|
removeMarker( Marker marker) |
None | Removes a marker. |
|
setCurrentZoomLevel( int zoom) |
None | Sets the zoom level to specified zoom. |
|
zoomIn() |
None | Zooms in on the map if the map is not already all the way zoomed in. |
|
zoomOut() |
None | Zooms out on the map if the map is not already all the way zoomed out. |
SLMapOptions
This class represents optional arguments to the SLMap constructor. It has no constructor, but is instantiated as an object literal.
Properties
| Property | Default | Description |
|---|---|---|
| hasZoomControls | true | Whether the map has zoom controls. |
| hasPanningControls | true | Whether the map has pan controls. |
| doubleClickHandler | null | Specifies a double click function. |
| singleClickHandler | null | Specifies a single click function |
| onStateChangedHandler | null | Specifies an onstatechanged handler function |
| zoomMin | 6 | Specifies an minimum level a map can be zoomed to. Currently the maximum for this value is 7. |
| zoomMax | 1 | Specifies an maximum level a map can be zoomed to. Currently the minimum for this value is 1. |
The doubleClickHandler and singleClickHandler option can be assigned to call a function whenever a place on the map is double-clicked or single-clicked respectively. See the guide for more.
The onStateChangedHandler option can be assigned to call a function whenever the "state" of the map changes (i.e. whenever the map bounds change). Likewise, see the guide for more.
SLPoint
Not currently implemented.
XYPoint
Represents a point in 2D coordinate space.
Constructor
XYPoint ( Float x, Float y )
Creates an XYPoint object.
Properties
| Property | Default | Description |
|---|---|---|
| x | None | X coordinate |
| y | None | Y coordinate |
