Hello again,
I found that the crash is a PySide 1.1.0 bug:
https://groups.google.com/forum/?fromgroups#!topic/pyside/dNSzyupTFMU
It seems to be fixed in newer versions of PySide. Until I get it packaged on my
ubuntu I have to change my code like this:
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg as
_NavigationToolbar
from matplotlib.backends.backend_qt4 import cursord
from PySide.QtGui import QWidget, QVBoxLayout, QApplication, QCursor
class NavigationToolbar(_NavigationToolbar):
def set_cursor( self, cursor ):
QApplication.restoreOverrideCursor()
qcursor = QCursor()
qcursor.setShape(cursord[cursor])
QApplication.setOverrideCursor( qcursor )

Objet: [Matplotlib-users] core dumped using NavigationToolbar with PySide
Hello,
I think I found a bug using NavigationToolbar with Pyside.
******** my system ********
OS: ubuntu 12.04
`uname -a`: Linux parcouss-M720T-M730T 3.2.0-26-generic-pae #41-Ubuntu SMP Thu
Jun 14 16:45:14 UTC 2012 i686 i686 i386 GNU/Linux
matplotlib version: 1.1.1rc (ubuntu distribution package)
PySide version: 1.1.0 (ubuntu distribution package)
******** how to reproduce the bug ********
Here is a simple script to get the core dumped crash:
import matplotlib
matplotlib.use('Qt4Agg')
matplotlib.rcParams['backend.qt4']='PySide'
from matplotlib.figure import Figure
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg as
NavigationToolbar
from PySide.QtGui import QWidget, QVBoxLayout , QApplication
import sys
class Main(QWidget):
def __init__(self):
QWidget.__init__(self)
self.setLayout(QVBoxLayout())
self.canvas = FigureCanvas(Figure())
self.toolbar = NavigationToolbar(self.canvas, self)
self.layout().addWidget(self.toolbar)
self.layout().addWidget(self.canvas)
if __name__ == '__main__':
app = QApplication(sys.argv)
m = Main()
m.show()
app.exec_()
It may be relative to a mousemoveent, as it does not
crash until I move the mouse on the window.

BTW: thanks to the really great matplotlib framework :)
