# MarbleMap Class Reference

`from PyKDE4.marble import *`

Inherits: QObject
Namespace: Marble.MarbleMap

## Detailed Description

A class that can paint a view of the earth.

FIXME: Change this description when we are done.

This class can paint a view of the earth or any other globe, depending on which dataset is used. It can be used to show the globe in a widget like MarbleWidget does, or on any other QPaintDevice.

The projection and other view parameters that control how MarbleMap paints the map is given through the class ViewParams. If the programmer wants to allow the user to control the map, he/she has to provide a way for the user to interact with it. An example of this can be seen in the class MarbleWidgetInputHandler, that lets the user control a MarbleWidget that uses MarbleMap internally.

The MarbleMap needs to be provided with a data model to work. This model is contained in the MarbleModel class. The widget can also construct its own model if none is given to the constructor. This data model contains 3 separate datatypes: tiles which provide the background, vectors which provide things like country borders and coastlines and placemarks which can show points of interest, such as cities, mountain tops or the poles.
