I don’t really understand what you are trying to achieve, but the ‘user_ns’ dictionary isn’t an isolated namespace - it’s the namespace that is used by the console, and I would have thought you would have to do some kind of injection to add other objects from
within the application. The following code is added shortly after the example I gave in the MainWindow class:
<div><br>
</div>
<div>
<div> self.user_ns['plotview'] = self.plotview</div>
<div> self.user_ns['treeview'] = self.treeview</div>
<div> self.user_ns['mainwindow'] = self</div>
<div><br>
</div>
<div>so that other parts of the application are accessible within the console. You could add all the items in the globals() dictionary if you wanted:</div>
<div><br>
</div>
<div>
<div> for k, v in globals().items():</div>
<div> self.user_ns[k] = v</div>
</div>
<div><br>
</div>
<div>which is presumably equivalent to what Matthias suggested, but you would still have to inject new variables as they are created. </div>

<blockquote type="cite">Thanks Ray. Unfortunately, I want the ipython console's namespace to reflect that of the application in which it is embedded, not a specific widget. There is an example that appears to do this at <a href="https://github.com/ipython/ipython/blob/master/examples/Embedding/embed_function.py" target="_blank">https://github.com/ipython/ipython/blob/master/examples/Embedding/embed_function.py</a>
, but I'm trying to do the same with the Qt widget. At the top of my main gui module, I do:<br>
<div><br>
</div>
<div>
<div>try:</div>
<div> from IPython.qt.console.rich_ipython_widget import RichIPythonWidget</div>
<div> from IPython.qt.inprocess import QtInProcessKernelManager</div>
<div><br>
</div>
<div> # Create an in-process kernel</div>
<div> kernel_manager = QtInProcessKernelManager(user_ns=None)</div>
</div>

<div style="word-wrap:break-word">
<div>Don't you want to just pass `globals()` instead of `None` here? </div>
<div>user_ns kwarg here is **the mutable namespace** (i.e. a dict) you want your kernel to work on. If you pass None, </div>
<div>it will create a new empty object for you. If you pass `{"a":1}` then your kernel will see a variable `a` with a value of 1 (mutable) </div>
<div><br>
</div>
<div>So I guess what you want to pass here is either globals(), locals(), or a dict you constructed yourself, </div>
<div>from the bit you want available. </div>
<div><br>
</div>
<div>You can also do as raymond said, and inject things into user_ns after getting the reference to it. </div>
