Hi Ryan,
wow! This tutorial is one of the best I ever encountered. Nothing is missing,
nothing is cryptic or unclear. What I like best is, that it get's along without
using Qt Designer plugins or something similar strange. It's a good basis to
start. Maybe you should write a book, covering all the untold things one needs
to solve problems like that. I browsed through plenty of books the last weeks
and what really is missing, is a cookbook about Qt Designer, Glade and
wxWidgets and how to fill it with python3 and it's lib's like matplotlib,
pyqtgraph, numpy, sympy etc.
I would buy it right away!cheers,Christian

Christian,
As it turns out, I wrote a blog post (for my terrible blog) about using
Designer to create a MPL based GUI
(http://blog.rcnelson.com/building-a-matplotlib-gui-with-qt-designer-part-1/).
I was going to write this up for the MPL docs... But it got really long (3
parts), so I just used my personal site. It got so long because this was the
second time I needed to figure this out, and I wanted to make a very detailed
outline for my own future reference. Unfortunately, I don't have any experience
with Qt5, but I imagine things are similar. I think they just rearranged the
locations of some of the widgets, but I'd be curious to hear your experience. I
gave up on PyQtdesignerplugins. I think it makes more sense to just use a
generic widget as the MPL container.
I would be very happy if you had comments for my Qt designer posts.

Hi Ryan,
could you write down, as a tutorial, how you built the example with the qt
designer?In the last hours I read all most everything what can be found on the
issue of getting matplotlib running with pyqt5 and the designer but as you
realized yourself, there is little to be found handy.
I'm stuck at a project, which has to use python3, and pyqt5 and am not allowed
by my boss to fall back to pyqt4 or qt_compat. He wants to make sure that we
use the latest revisions.
So I#m very pleased to read that someone already set food on this terrain.
Qt5.4.1 is running and I installed PyQtdesingerplugins, in mind that they were
written for PyQt4. Are they usable in 5? I added the env-variables to my
bashrc, did get any changes shown in the designer. Of course I did a re-log-in
to start fresh, but any changes were noteable.What possible ways of embedding
matplotlib into a designer base pyqt5-gui else, are there?
cheers,Christian

Hello list,
A couple months ago, I spent quite a bit of time trying to figure out how to
use Qt designer create a GUI with an embedded MPL window. Unfortunately, the
Scipy cookbook page
(http://wiki.scipy.org/Cookbook/Matplotlib/Qt_with_IPython_and_Designer) is
very outdated. A recent post
(http://matplotlib.1069221.n5.nabble.com/Re-Keep-list-of-figures-or-plots-and-flip-through-list-using-UI-td44961.html)
brought up some questions about a use case very similar to mine, so I redid my
example and was going to write a quick tutorial for the docs.
Unfortunately, I'm not a Qt guru, so I thought that I would ask on the list for
some advice. The OP and I were both interested in being able to have a list of
figures that you could select from to change the plot window. The embedding
examples in the docs create subclasses of FigureClass* and embed the plotting
figure/axes/etc. This works but gets tricky, though, when trying to switch
plots. Also, for interactive IPython work, I didn't like that the plotting
objects were mixed in with all the QtGui.QWidget attributes, which makes
introspective searching painful. My solution was to create a dictionary of
matplotlib.figure.Figure objects that had all of the plotting stuff defined.
Then when I select a new plot from the list, the old one is removed and a new
FigureClass object is created using the selected Figure object. Has anyone else
successfully done something like this? Is there a better way? Also, it seems if
I zoom the current plot, change to a new plot, and change back, the zoom region
is retained. Anyone know how to reset the zoom region?
Attached is my example: "window.py" is the Designer-created main window and
"custommpl.py" is the subclass of the main window that I wrote. It's about as
short as I could make it.
Thanks
Ryan
