Matplotlib爲格萊德/ GTK控件：移植到新版本

Question

我發現這個教程的空地/ GTK窗口內顯示matplotlib積：

http://matplotlib.org/examples/user_interfaces/mpl_with_glade.html

我不知道的是哪個版本本教程使用的許多軟件包。如何將此代碼移植到最新版本的GTK和Glade？

林間空地文件可以在這裏找到：

https://github.com/matplotlib/matplotlib/blob/master/examples/user_interfaces/mpl_with_glade.glade

我有一個簡單的版本工作。隨意發佈改進。我還發布了一個pull請求，所以這可能會被添加到matplotlib文檔中。

的Python 3檔：

#!/usr/bin/env python3 

    from gi.repository import Gtk, Gio 

    from matplotlib.figure import Figure 
    from matplotlib.axes import Subplot 
    from numpy import arange, sin, pi 
    from matplotlib.backends.backend_gtk3agg import FigureCanvasGTK3Agg as FigureCanvas 

    import sys 

    class Window1Signals: 
     def on_window1_destroy(self, widget): 
      Gtk.main_quit() 

    def main(): 
     builder = Gtk.Builder() 
     builder.add_objects_from_file("mpl_with_glade_316.glade", ("window1", "")) 
     builder.connect_signals(Window1Signals()) 
     window = builder.get_object("window1") 
     sw = builder.get_object("scrolledwindow1") 

     #Start of Matplotlib specific code 
     ########################################################################## 
     figure = Figure(figsize=(8,6), dpi=71) 
     axis = figure.add_subplot(111) 
     t = arange(0.0, 3.0, 0.01) 
     s = sin(2*pi*t) 
     axis.plot(t,s) 

     axis.set_xlabel('time [s]') 
     axis.set_ylabel('voltage [V]') 

     canvas = FigureCanvas(figure) # a Gtk.DrawingArea 
     canvas.set_size_request(800,600) 
     sw.add_with_viewport(canvas)  
     ########################################################################## 
     #End of Matplotlib specific code  

     window.show_all() 
     Gtk.main() 

    if __name__ == "__main__": 
     main() 

格萊德代碼：
