GTK-Glade tutorial is out of date

[tobias47n9e]

The tutorial that puts a Matplotlib widget into a GTK application using the Glade interface designer, is out of date. The version used in the tutorial is Glade 2.x, and that file doesn't work anymore since Glade 3.x. It would be good to have a working tutorial for Glade 3.16 using GTK3.x (3.10 would be ideal), and Python 3.

I am trying to build a working example myself, but I just started with this kind of programming. So if anybody beats me to it, it would also be great and appreciated.

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

Maybe we want to just drop this section of the docs for 1.4.0 and put it back when we get it fixed?

It might still work with Glade2.x and older versions of GTK. I just haven't tried that out. I have a working Python3-Glade3 application, but I just can't figure out how to place the matplotlib-widget into it.

This it what I have so far. I can open a GTK-3.10 window by running a Python 3 program that opens a Glade 3.16.1-file.

My python 3 file:

#!/usr/bin/env python

from gi.repository import Gtk, Gio

from matplotlib.figure import Figure
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_simple.glade", ("window1", "") )
    builder.connect_signals(Window1Signals())

    window = builder.get_object("window1")
    window.show_all()

    Gtk.main()

if __name__ == "__main__":
    main()

and my glade file (name: "mpl_with_glade_simple.glade"):

<?xml version="1.0" encoding="UTF-8"?>
<!-- Generated with glade 3.16.1 -->
<interface>
  <requires lib="gtk+" version="3.10"/>
  <object class="GtkApplicationWindow" id="window1">
    <property name="can_focus">False</property>
    <signal name="destroy" handler="on_window1_destroy" swapped="no"/>
    <child>
      <placeholder/>
    </child>
  </object>
</interface>

I think I got it to work: #3088
