How to integrate Ipython console in PyQT application

Question

I am developing PyQt software for my lab. In this software, I load various kinds of RAW and parse data from mySQL database (usually in arrays).

I would like to integrate the Iython console into the widget so that I can easily interact with this data.

I had some difficulties with Ipython 0.13 to do this.
Here is what I already have (all the code is very long, so I just show the part containing the widget, Ipython console and the corresponding import line, if you need more, just tell me):

##I load everything useful to my application, including the following line from IPython.frontend.qt.console.qtconsoleapp import IPythonQtConsoleApp ##then is my whole software ##here is a class containing the Graphical User Interface elements. A button call the following function. self.Shell_Widget is the widget containing the Ipython console, self.MainWindow is the application mainwindow def EmbeddedIpython(self): """ This function should launch an Ipython console """ self.Shell_Widget = QtGui.QDockWidget(self.MainWindow) #Widget creation self.MainWindow.addDockWidget(4,self.Shell_Widget) self.Shell_Widget.setMinimumSize(400,420) console = IPythonQtConsoleApp() #Console Creation console.initialize() console.start() self.Shell_Widget.show() 

So, as needed, the Ipython console starts up and seems to work, but I can't access all the application variables, arrays, etc. I think the Ipython console runs regardless of my software, but here is my programming limitation ... Does anyone know how to run Ipython in my application? Perhaps a missing parameter or other way to integrate Ipython.

for information, this does not work: Deploying the IPython Qt console in a PyQt application

Thank you for your help!

The link mentioned link seems to work flawlessly:
