[Nexus] PyQt and nxs files

[Osborn, Raymond]

The getOpenFileName function returns a tuple containing the file name and the selected file filter. Since you only want the first value, you should change the line to

    name, _ = QtGui.QFileDialog.getOpenFileName(self, 'Open file','/home')

You may want to have a look at the NeXpy application to see if it does some of what you are looking for. It uses PySide rather than PyQt, although I am hoping to make it agnostic soon. You can find more details at http://nexpy.github.io/nexpy/.

Dear all,

I am trying to develop a GUI software that reads the nxs files. I decide
to use the PyQt in order to have a nice interface. However I am having
problems to open the nxs file:
I was trying the following commands:

   fname = QtGui.QFileDialog.getOpenFileName(self, 'Open file','/home')

   f=nxs.open(fname,'r')


The compilation gave me the following Error message:
ctypes.ArgumentError: argument 1: <type 'exceptions.TypeError'>: wrong type

I would appreciate some help to solve this problem to open the nxs files.

Thanks in advance

Fabiano
