MarbleModel Class Reference
from PyKDE4.marble import *
Inherits: QObject
Namespace: Marble
Detailed Description
The data model (not based on QAbstractModel) for a MarbleWidget.
This class provides a data storage and indexer that can be
displayed in a MarbleWidget. It contains 3 different 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.
The tiles provide the background of the image and can be for
instance height and depth fields, magnetic strength, topographic
data or anything else that is area based.
The vectors provide things like country borders and
coastlines. They are stored in separate files and can be added or
removed at anytime.
The placemarks contain points of interest, such as cities,
mountain tops or the poles. These are sorted by size (for cities)
and category (capitals, other important cities, less important
cities, etc) and are displayed with different color or shape like
square or round.
