MarbleWidget Class Reference

from PyKDE4.marble import *

Inherits: QWidget → QObject
Namespace: Marble.MarbleWidget

Detailed Description

A widget class that displays a view of the earth.

This widget displays a view of the earth or any other globe, depending on which dataset is used. The user can navigate the globe using either a control widget, e.g. the MarbleControlBox, or the mouse. The mouse and keyboard control is done through a MarbleWidgetInputHandler. Only some aspects of the widget can be controlled by the mouse and/or keyboard.

By clicking on the globe and moving the mouse, the position can be changed. The user can also zoom by using the scroll wheel of the mouse in the widget. The zoom value is not tied to any units, but is an abstract value without any physical meaning. A value around 1000 shows the full globe in a normal-sized window. Higher zoom values give a more zoomed-in view.

The MarbleWidget needs to be provided with a data model to work. This model is contained in the MarbleModel class, and it is painted by using a MarbleMap. The widget can also construct its own map and model if none is given to the constructor. A MarbleModel 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.

In addition to navigating with the mouse, you can also use it to get information about items on the map. You can either click on a placemark with the left mouse button or with the right mouse button anywhere on the map.

The left mouse button opens up a menu with all the placemarks within a certain distance from the mouse pointer. When you choose one item from the menu, Marble will open up a dialog window with some information about the placemark and also try to connect to Wikipedia to retrieve an article about it. If there is such an article, you will get a mini-browser window with the article in a tab.

The right mouse button controls a distance tool. The distance tool is implemented as a menu where you can choose to either create or remove so called Measure Points. Marble will keep track of the Measure Points and show the total distance in the upper left of the widget. Measure Points are shown on the map as a little white cross.

This function is connected to the models signal with the same name. When the model needs to create a cache of tiles in several different resolutions, it will emit creatingTilesStart once with a name of the theme and a descriptive text. The widget can then pop up a dialog to explain why there is a delay.
