Hi Dane,
Woudl it be possible to incorporate a open file dialog so we can open
the xml file.
Have a look at the code below. The def showDialog is not complete.

class MapnikWidget(QWidget):
def __init__(self, parent = None):
QWidget.__init__(self, parent)
self.map = mapnik.Map(256, 256)
self.qim = QImage()
self.startDragPos = QPoint()
self.endDragPos = QPoint()
self.drag = False
self.scale = False
self.timer = QTimer()
self.timer.timeout.connect(self.updateMap)
self.total_scale = 1.0
openFile = QtGui.QAction(QtGui.QIcon('open.png'), 'Open', self)
openFile.setShortcut('Ctrl+O')
openFile.setStatusTip('Open new File')
self.connect(openFile, QtCore.SIGNAL('triggered()'), self.showDialog)
menubar = self.menuBar()
fileMenu = menubar.addMenu('&File')
fileMenu.addAction(openFile)
def showDialog(self):
filename = QtGui.QFileDialog.getOpenFileName(self, 'Open file',
'/home')
fname = open(filename)
data = fname.read()
def load_map(self, xml):
self.map = mapnik.Map(256, 256)
mapnik.load_map(self.map, xml)
self.map.resize(self.width(), self.height())
self.zoom_all()
