Deprecated. Use net.rim.device.api.lbs.maps.ui.MapField or net.rim.device.api.lbs.maps.ui.RichMapField instead.

public class MapField
extends Field

Renders a map using the current mapping service.

There are three basic ways to navigate the MapField:

And there are two basic ways to change the currently displayed view:

Note: In any conversion or navigation (move) methods, world coordinates are used whereby the valid ranges for latitude values are inclusive for -9000000 to 9000000, and; longitude values are inclusive for -18000000 to 18000000. Methods using WGS84 coordinates become converted to world coordinates are subject to this validation.

You can also use the MapField and the RichMapField that are defined in net.rim.device.api.lbs.maps.ui to render maps. These classes were released in BlackBerry Java SDK 6.0, and provide extended services and functions over this MapField.

layout

protected void layout(int width,
                      int height)
Deprecated. 
Description copied from class: Field
Lays out field contents.

This method is abstract; any class that extends Field must implement this method appropriate to its needs.

This method is invoked after the screen has been created, or when system parameters change (for example, after a system font change). Field.getExtent() will return a valid value after this method is invoked. Implementations of this method must invoke Field.setExtent(int, int) with the size used by the field.

During this call, Field.setExtent(int, int) must be called with parameters such that both width and height are between 0 and the values passed into this function for the Manager to be able to position this Field properly.

Fields may cache system attributes for efficiency (such as the current system font); however, they cannot depend on these attributes remaining unchanged. When one of these attributes changes, a message event is sent to that effect. In these cases, this method refetches and caches these attributes.

Specified by:
layout in class Field
Parameters:
width - The amount of available horizontal space.
height - The amount of available vertical space.

Field.layout(int, int)
