Editable overshooting

See attached screen-shot.

Steps to reproduce:
1. Run the below program
2. Change column width of any column below 150px
3. Start editing

The editable spans the column width.

What happens:
The editable exceeds column width.

PyGi program

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk

#list of tuples for each software, containing the software name, initial release, and main programming languages used
software_list = [("Firefox", 2002,  "C++"),
                 ("Eclipse", 2004, "Java" ),
                 ("Pitivi", 2004, "Python"),
                 ("Netbeans", 1996, "Java")]

class TreeViewWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="Treeview Filter Demo")

        #Setting up the self.grid in which the elements are to be positionned = Gtk.Box()

        #Creating the ListStore model
        self.software_liststore = Gtk.ListStore(str, int, str)
        for software_ref in software_list:

        #Creating the treeview
        self.treeview = Gtk.TreeView.new_with_model(self.software_liststore)
        for i, column_title in enumerate(["Software", "Release Year", "Programming Language"]):
            renderer = Gtk.CellRendererText()
            renderer.set_property("editable", True)
            column = Gtk.TreeViewColumn(column_title, renderer, text=i)
            column.props.resizable = True


win = TreeViewWindow()
win.connect("delete-event", Gtk.main_quit)

cell renderer text: Allow entries to shrink

Set a small max-width on entries used for editing cells, so they
adapt to small columns and don't overlap the next column.

Thank you for the prompt fix. Is there any specific reason why the width_chars property is set to 5. Why not set it to 1 so that the editable will span the column width for the smallest of columns?
