Veusz inside custom PyQt4 application, hello world

I am trying to build a PyQt4 application that uses veusz, but I am having
difficulties.  I am a relative newbie to PyQt4 and Veusz, but here is a Hello
World that shows what I am trying to do.

#!/usr/bin/env python

# A hello world example of using veusz in a PyQt4 app.

import numpy
import sys

from PyQt4 import QtCore, QtGui
app = QtGui.QApplication(sys.argv)

import veusz.windows.plotwindow
import veusz.document as document
from veusz.document.commandinterface import CommandInterface

class HelloMainWindow(QtGui.QMainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self)

        self.statusBar().showMessage('Hello Veuz World!')

        menubar = self.menuBar()
        self.file_menu = menubar.addMenu('&File')

        self.exit_action = QtGui.QAction(QtGui.QIcon('icons/exit.png'), '&Quit',
self)
        self.exit_action.setShortcut('Ctrl+Q')

OK, finally figured it out.

Turns out that doesn't work.  Veusz need some initialization functions.  The
following is needed instead.  Note stylesheet has to be imported before 
Application.

import veusz.setting.stylesheet
from veusz.application import Application
app = Application(sys.argv)

Matt,


That sounds frustrating.


Jeremy,
Is there some reason we can't add:
> import veusz.setting.stylesheet
to the top of
> veusz.application
and avoid this sort of problem?
