Detailed Description

Rectangles are polygons with fixed latitudes and longitudes for the north, south, east, and west boundaries. Moving a vertex of the Rectangle updates the appropriate edges accordingly.

updateBounds()

void com.google.appinventor.components.runtime.Rectangle.updateBounds	(	double	north,
		double	west,
		double	south,
		double	east
	)

Updates the rectangle from the native view. This method should not attempt to update the native view as this may result in an infinite loop since the update may call this implementation.

Parameters

north	the north latitude of the rectangle bounds
west	the west longitude of the rectangle bounds
south	the south latitude of the rectangle bounds
east	the east longitude of the rectangle bounds

Implements com.google.appinventor.components.runtime.util.MapFactory.MapRectangle.
