Does anybody know why the show._needmain stuff is needed in the show() function
in backend_tkagg.py? Currently, this function is as follows:
def show():
"""
Show all the figures and enter the gtk mainloop
This should be the last line of your script. This function sets
interactive mode to True, as detailed on
http://matplotlib.sf.net/interactive.html
"""
for manager in Gcf.get_all_fig_managers():
manager.show()
import matplotlib
matplotlib.interactive(True)
if rcParams['tk.pythoninspect']:
os.environ['PYTHONINSPECT'] = '1'
if show._needmain:
Tk.mainloop()
show._needmain = False
show._needmain = True
If I remove the show._needmain stuff, as in:
def show():
"""
Show all the figures and enter the gtk mainloop
This should be the last line of your script. This function sets
interactive mode to True, as detailed on
http://matplotlib.sf.net/interactive.html
"""
for manager in Gcf.get_all_fig_managers():
manager.show()
import matplotlib
matplotlib.interactive(True)
if rcParams['tk.pythoninspect']:
os.environ['PYTHONINSPECT'] = '1'
Tk.mainloop()
then the function still seems to work fine, and multiple show()s also works.
