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?
