Python - CellRendererText in GTK+ 3

Last Updated : 29 Aug, 2020

Gtk.CellRenderer widgets are used to display information within widgets such as the Gtk.TreeView or Gtk.ComboBox. Below are the seven Gtk.CellRenderer widgets used for different purposes.

Gtk.CellRendererText
Gtk.CellRendererToggle
Gtk.CellRendererPixbuf
Gtk.CellRendererCombo
Gtk.CellRendererProgress
Gtk.CellRendererSpinner
Gtk.CellRendererSpin
Gtk.CellRendererAccel

In this tutorial, we are going to discuss Gtk.CellRendererText. A Gtk.CellRendererText renders a given text in its cell, using the font, color, and style information provided by its properties.

Text in Gtk.CellRendererText widget can be make editable by

cell.set_property("editable", True)

Example :

Python3

from gi.repository import Gtk
import gi

gi.require_version("Gtk", "3.0")


class CellRendererTextWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title ="Geeks For Geeks")

        self.set_default_size(400, 400)

        self.liststore = Gtk.ListStore(str, str)
        self.liststore.append(
            ["Python Archives", "https://www.geeksforgeeks.org/category/programming-language/python/"])
        self.liststore.append(
            ["Python-GTK Archives", "https://www.geeksforgeeks.org/tag/python-gtk/"])
        self.liststore.append(
            ["Data Structures Archives", "https://www.geeksforgeeks.org/category/data-structures/"])
        self.liststore.append(
            ["Algorithms Archives", "https://www.geeksforgeeks.org/category/algorithm/"])

        treeview = Gtk.TreeView(model = self.liststore)

        renderer_text = Gtk.CellRendererText()
        column_text = Gtk.TreeViewColumn("Text", renderer_text, text = 0)
        treeview.append_column(column_text)

        renderer_editabletext = Gtk.CellRendererText()
        renderer_editabletext.set_property("editable", True)

        column_editabletext = Gtk.TreeViewColumn(
            "Editable Text", renderer_editabletext, text = 1)

        treeview.append_column(column_editabletext)

        renderer_editabletext.connect("edited", self.text_edited)

        self.add(treeview)

    def text_edited(self, widget, path, text):
        self.liststore[path][1] = text


win = CellRendererTextWindow()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()
