That's cool. I just found the book provided the right level of detail for
me to start using QtDesigner with my projects. I can't speak for PyQt5 but
I don't see the concepts have changed much over the past 5 or so years.
problems that frustrate the learning process.
Post by Christian AmbrosNo offense, but it really is outdated. Consider that it'll take two years
to do the writing and the lecture work the research material is form 2007
to 2008. We now are in 2015. As you can tell from other books which have
been published between 2013 and a really helpy book from March, 24th 2015
(yes, Benjamin Root wrote it), even they don't cover latest enhancements up
to six month before print, (which might be seen a reasonable since changing
is easy in a digitized world like ours).
A good tutorial for the once, who do not have much experience in this
field (I count myself in with the just one and a half year of experience in
gui programming) is two things, actual up to six month to a year and
straight forward, meaning It tells you what to do and doesn't bother you
with design thoughts, API explanations nor tries to teach you programming.
I have that book in my possession, but it didn't turn out to be helpful
if you do not have the time do read it in whole. If you have the time to
spin freely, you still will have conquered 80% by yourself and because it
is still outdated for pyhton3 and matplotlib 1.4.3 the use is questionable.
cheers,
Christian

Can I recommend this book. It was very helpful to me in figuring much of
this out.

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
