I was commenting that the issue you are having with getting easy-to-use pre-built figures in a non-interactive program without dragging pyplot in is the same as what I think the root of 2503 is and the re-factor I proposed to make your life easier would also help that case (I think).
The gui backends were (as I understand it, someone please correct me if I am wrong) built to play nice with ipython to put together a MATLAB-like interface. The fact that you can then embed the gui-framework dependent bits of matplotlib in other gui applications is a nice side-effect, but not one of the initial design goals. This is why the figure_manager code is (too-)tightly coupled to _pylab_helpers.
See the examples at http://matplotlib.org/examples/user_interfaces/ making a window with a canvas + tool bar is pretty easy.
A quick and dirty solution might be to just monkey patch the figure_manager.destroy function when your app starts up to remove the check that shuts down the main loop.

Hello everybody
Working on one GTK3 app, that calls matplotlib to plot some figures, I
found that closing all the figures from matplotlib kills my app also.
The problem…
Gtk.main() is called only if there is no previous invocation, in my
case, my Gtk3 app invokes main, so the mainloop won’t call it again.
#in backend_gtk3.py
class Show(ShowBase):
def mainloop(self):
if Gtk.main_level() == 0:
Gtk.main()
But in the “destroy” method of the figure manager calls Gtk.main_quit
everytime that there are no more figures
#in backend_gtk3.py inside destroy method of FigureManagerGTK3
if Gcf.get_num_fig_managers()==0 and \
not matplotlib.is_interactive() and \
Gtk.main_level() >= 1:
Gtk.main_quit()
So basically we are not calling Gtk.main but we are Gtk.calling
main_quit.
Isn’t it more natural to call Gtk.main the same amount of times that
we are going to call Gtk.main_quit?
Adding matplotlib.rcParams[‘interactive’] = True doesn’t help
Here is my little testing code
##############################
#file myapp.py
import matplotlib
matplotlib.rcParams[‘interactive’] = True
matplotlib.use(‘GTK3AGG’)
import matplotlib.pyplot as plt
from gi.repository import Gtk
class MyWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Hello World")
self.button = Gtk.Button(label="Click Here")
self.button.connect("clicked", self.on_button_clicked)
self.add(self.button)
def on_button_clicked(self, widget):
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot([1,2,3])
plt.show()
win = MyWindow()
win.connect(“delete-event”, Gtk.main_quit)
win.show_all()
Gtk.main()
#########################
I know this is related to interactive mode, but running from console
python myapp.py
reproduces the problem
Why hasattr(sys, ‘ps1’) is False? if I am running it from console? how
do I change this?
Thanks
Federico
P.S. Does anybody had the time to check my PR for
multi-figure-manager?

Sorry, the replay-all is not my default.
In that case it is easier for me to monkey patch just the mainloop to
invoke Gtk.main everytime.
But again, even if we are talking about interactive (ipython), why is
it unbalanced?
I mean calls Gtk.main vs Gtk.main_quit?

Looking through the code I realize that in interactive mode (ipython)
there is no call to show() by default.
And if you call it, it does not call mailoop because is_interactive==Tr
ue
So why is there the restriction to call only once Gtk.main in mailoop?
if it is not called anyway
Why not make that restriction to call Gtk.main in mainloop dependant
on is_interactive? as the call Gtk.main_quit is in the destroy method
