python-2.7 - 如何在 PyQT 应用程序中集成 Ipython 控制台

Question

我正在为我的实验室开发 PyQt 软件。在这个软件中，我从 mySQL 数据库(通常在数组中)加载不同类型的 RAW 和分析数据。

我想在 Widget 中集成 Iython 控制台，以便我可以轻松地与这些数据进行交互。

我在使用 Ipython 0.13 时遇到了一些困难。
这是我已经拥有的(整个代码很长，所以我只展示了包含小部件的部分，Ipython 控制台和相应的导入行，如果您需要更多，请告诉我):

##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()

因此，根据需要，启动了一个 Ipython 控制台，并且似乎可以工作，但我无法访问整个应用程序变量、数组等......我认为 Ipython 控制台是独立于我的软件启动的，但这是我的编程限制...
有人知道如何在我的应用程序中启动 Ipython 吗？也许缺少参数，或者集成 Ipython 的不同方式。

有关信息，这不起作用:

感谢您的帮助!!
