Hello Marble!

Marble offers KDE-Python bindings. A small hello world example is available as part of the Marble sources at

The Marble API allows a very easy integration of a map widget into your application. Let's prove that with some python code:

!env python

A very simple example of how to use the marble widget.

from PyKDE4.marble import *
import sys
class MainWin (KMainWindow):

   def __init__ (self, *args):
       KMainWindow.__init__ (self)
       self.resize(640, 480)

       self.marble = Marble.MarbleWidget(self)
       self.marble.setMapThemeId("earth/bluemarble/bluemarble.dgml")
       self.setCentralWidget(self.marble)
       self.marble.centerOn(5.8333, 51.8333)
       self.marble.zoomView(2000)

def main():

   appName     = "simple_marble"
   catalog     = ""
   programName = ki18n ("default")

                             license, copyright, text, homePage, bugEmail)

   aboutData.addAuthor (ki18n("Simon Edwards"), ki18n("Developer"))

   mainWindow.show()
   app.connect(app, SIGNAL ("lastWindowClosed ()"), app.quit)
   app.exec_()
