Detailed Description

MapFeature is the root class of all features that are placed on the map. It inherits from the Component interface since all MapFeatures are naturally components. MapFeature defines the properties that are generally required by any map feature that should be implemented for App Inventor.

Parameters

visitor	a visitor that will operate on the feature.
arguments	any additional arguments to pass to the visitor's visit function.
<T>	the return type of the visitor's visit function.

Returns: the value returned by the visitor's visit function applied to the feature.

◆ Draggable() [1/2]

boolean com.google.appinventor.components.runtime.util.MapFactory.MapFeature.Draggable ( )

Gets whether the map feature is draggable on the map.

Returns: true if the feature should be draggable by the end user, otherwise false.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ Draggable() [2/2]

void com.google.appinventor.components.runtime.util.MapFactory.MapFeature.Draggable ( boolean draggable )

Sets whether the map feature is draggable on the map, assuming that the map implementation supports dragging features.

Parameters

draggable true if the feature should be draggable by the app user, otherwise false.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ EnableInfobox() [1/2]

boolean com.google.appinventor.components.runtime.util.MapFactory.MapFeature.EnableInfobox ( )

Gets whether the infobox will automatically show when the user taps the feature

Returns: true if the infobox will show automatically, otherwise false.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ EnableInfobox() [2/2]

void com.google.appinventor.components.runtime.util.MapFactory.MapFeature.EnableInfobox ( boolean enable )

Sets whether the infobox should automatically show when the app user taps the feature

Parameters

enable true if the infobox should automatically show when the feature is tapped by the app user, otherwise false.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ getCentroid()

GeoPoint com.google.appinventor.components.runtime.util.MapFactory.MapFeature.getCentroid ( )

Gets the centroid of the feature.

Returns: the feature's centroid.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ getGeometry()

Geometry com.google.appinventor.components.runtime.util.MapFactory.MapFeature.getGeometry ( )

Gets the geometry of the feature, used for calculating distance and bearing measures.

Returns: the feature's geometry

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ HideInfobox()

void com.google.appinventor.components.runtime.util.MapFactory.MapFeature.HideInfobox ( )

Hides the feature's infobox if it is visible. Otherwise, this method has no effect.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ LongClick()

void com.google.appinventor.components.runtime.util.MapFactory.MapFeature.LongClick ( )

Runs when the user long-presses on the feature but does not trigger a drag. Note that this event will only run if Draggable() is false.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

Shows the infobox for the feature even if it is not visible. Otherwise, this method has no effect. This method can be used to show the infobox even if EnableInfobox() is false.

Implemented in com.google.appinventor.components.runtime.MapFeatureBase.

◆ StartDrag()

void com.google.appinventor.components.runtime.util.MapFactory.MapFeature.StartDrag ( )

Runs when the user begins a drag operation on the feature.
