我正在使用Python3和Glade，我需要在动态变化的GtkBox中嵌入一个情节，我按照本教程进行操作：
http://gtk3-matplotlib-cookbook.readthedocs.org/en/latest/hello-plot.html#embedding-matplotlib
似乎没有任何事情发生，我在执行过程中遇到了错误：
main.py:78：警告：尝试删除时未找到源ID 39 Gtk.main（）
这是关于情节的代码的一部分：
print("plot")
figure = Figure(figsize=(5,5), dpi=100)
ax = figure.add_subplot(111)
N = 20
theta = linspace(0.0, 2 * pi, N, endpoint=False)
radii = 10 * random.rand(N)
width = pi / 4 * random.rand(N)
bars = ax.bar(theta, radii, width=width, bottom=0.0)
for r, bar in zip(radii, bars):
bar.set_facecolor(cm.jet(r / 10.))
bar.set_alpha(0.5)
print("pre-plot")
ax.plot()
print("post-plot")
canvas = FigureCanvas(figure) # a Gtk.DrawingArea
containerbox.remove(schermata1) #schermata1= GTKBOX
sw.add_with_viewport(canvas) #sw= GtkScrolledWindow
containerbox.add(schermata2) #schermata2= GtkBox whit sw inside
我的进口商品：
from gi.repository import Gtk
from numpy import arange, pi, random, linspace
from matplotlib.figure import Figure
from matplotlib.axes import Subplot
from numpy import arange, sin, pi
import matplotlib.cm as cm
from matplotlib.backends.backend_gtk3cairo import FigureCanvasGTK3Cairo as FigureCanvas
