Tkinter GUI Application Development Blueprints, Second Edition

Making a Text Editor

We got a fairly high-level overview of Tkinter in Chapter 1, Meet Tkinter. Now that we know some things about Tkinter's core widgets, geometry management, and the binding of commands and events to callbacks, let's use our skills in this project to create a text editor.

We will, in the process of creating a text editor, take a closer look at some widgets and learn how to tweak them to meet our specific needs.

The following are the key objectives for this project:

  • Delving into some commonly used widgets, such as the Menu, Menubutton, Text, Entry, Checkbutton, and Button widgets
  • Exploring the filedialog and messagebox modules of Tkinter
  • Learning the vital concepts of indexing and tagging, as applied to Tkinter
  • Identifying the different types of Toplevel windows

Project overview

The goal here is to build a text editor with some nifty features. Let's call it the Footprint Editor:

We intend to include the following features in the text editor:

  • Creating new documents, opening and editing existing documents, and saving documents
  • Implementing common editing options such as cut, copy, paste, undo, and redo
  • Searching within a file for a given search term
  • Implementing line numbering and the ability to show/hide line numbers
  • Implementing theme selection to let a user choose custom color themes for the editor
  • Implementing the about and help windows

Getting started – setting up the editor skeleton

Our first goal is to implement the broad visual elements of the text editor. As programmers, we have all used text editors to edit code. We are mostly aware of the common GUI elements of a text editor. So, without further ado, let's get started.

The first phase implements the Menu, Menubutton, Label, Button, Text, and Scrollbar widgets. Although we'll cover all of these in detail, you might find it helpful to look at the widget-specific options in the documentation of Tkinter maintained by its author, Frederick Lundh, at http://effbot.org/tkinterbook/. You can also use the interactive shell, as discussed in Chapter 1, Meet Tkinter.

You might also want to bookmark the official documentation page of Tcl/Tk at http://www.tcl.tk/man/tcl8.6/TkCmd/contents.htm. This site includes the original Tcl/Tk reference. While it...

Adding a menu and menu items

Menus offer a very compact way of presenting a large number of choices to the user without cluttering the interface. Tkinter offers the following two widgets to handle menus:

  • Menu widget: This appears at the top of applications, which is always visible to end users
  • Menu items: These show up when a user clicks on a menu

We will use the following code to add Toplevel menu buttons:

my_menu = Menu(parent, **options)

For example, to add a File menu, we will use the following code:

# Adding Menubar in the widget
menu_bar = Menu(root)
file_menu = Menu(menu_bar, tearoff=0)
# all file menu-items will be added here next
menu_bar.add_cascade(label='File', menu=file_menu)
root.config(menu=menu_bar)

The following screenshot is the result of the preceding code (2.01.py):

Similarly, we will add the Edit, View, and About menus (2.01.py).

We will also define...

Implementing the View menu

Tkinter offers the following three varieties of menu item:

  • Checkbutton menu items: These let you make a yes/no choice by checking/unchecking the menu item
  • Radiobutton menu items: These let you choose an option from many different options
  • Cascade menu items: These menu items only open up to show another list of choices

The following View menu shows these three menu item types in action:

The first three menu items in the View menu let users make a definite yes or no choice by checking or unchecking thems. These are examples of the Checkbutton menu.

The Themes menu item in the preceding screenshot is an example of a Cascade menu. Hovering over this Cascade menu simply opens another list of menu items. However, we can also bind a menu item by using the postcommand=callback option. This can be used to manage something just before bringing up the cascading...

Adding a built-in functionality

Tkinter's Text widget comes with some handy built-in functionalities to handle common text-related functions. Let's leverage these functionalities to implement some common features in the text editor.

Let's start by implementing the cut, copy, and paste features. We now have the editor GUI ready. If you open the program and play with the Text widget, you will see that you can perform basic functions such as cut, copy, and paste in the text area by using Ctrl + X, Ctrl + C, and Ctrl + V, respectively. All of these functions exist without us having to add a single line of code for these functionalities.

The Text widget clearly comes with these built-in events. Now, we simply want to connect these events to their respective menu items.

The documentation of the Tcl/Tk universal widget methods tells us that we can trigger events without...

Indexing and tagging

Though we managed to leverage some built-in functionalities to gain a quick advantage, we need more control over the text area so that we can bend it to our will. This will require the ability to target each character or text location with precision.

We will need to know the exact position of each character, the cursor, or the selected area in order to do anything with the contents of the editor.

The Text widget offers us the ability to manipulate its content using index, tags, and mark, which let us target a position or place within the text area for manipulation.

Index

Indexing helps you target a particular place within a piece of text. For example, if you want to mark a particular word in bold, red...

Implementing the Select All feature

We know that Tkinter has a built-in sel tag that applies a selection to a given text range. We want to apply this tag to the entire text in the widget.

We can simply define a function to handle this, as follows (2.05.py):

def select_all(event=None):
content_text.tag_add('sel', '1.0', 'end')
return "break"

After doing this, add a callback to the Select All menu item:

edit_menu.add_command(label='Select All', underline=7, accelerator='Ctrl+A', command=select_all)

We also need to bind the function to the Ctrl + A keyboard shortcut. We do this by using the following key bindings (2.05.py):

content_text.bind('<Control-A>', select_all)
content_text.bind('<Control-a>', select_all)

The coding of the Select All feature is complete. To try it out, add some text...

Implementing the Find Text feature

Next, let's code the Find Text feature (2.05.py). The following screenshot shows an example of the Find Text feature:

Here's a quick summary of the desired functionality. When a user clicks on the Find menu item, a new Toplevel window opens up. The user enters a search keyword and specifies whether the search needs to be case-sensitive. When the user clicks on the Find All button, all matches are highlighted.

To search through the document, we rely on the text_widget.search() method. The search method takes in the following arguments:

search(pattern, startindex, stopindex=None, forwards=None, backwards=None, exact=None, regexp=None, nocase=None, count=None)

For the editor, define a function called find_text and attach it as a callback to the Find menu (2.05.py):

edit_menu.add_command(label='Find',underline= 0, accelerator...

Types of Toplevel window

Previously in this chapter, we used the following line of code:

search_toplevel.transient(root)

Let's explore what it means here. Tkinter supports the following four types of Toplevel window:

  • The main Toplevel window: This is the type we have been constructing so far.
  • The child Toplevel window: This type is independent of the root. The Toplevel child behaves independently of its root, but it gets destroyed if its parent is destroyed.
  • The transient Toplevel window: This always appears at the top of its parent, but it does not entirely grab the focus. Clicking again on the parent window allows you to interact with it. The transient window is hidden when the parent is minimized, and it is destroyed if the parent is destroyed. Compare this to what is called a modal window. A modal window grabs all the focus from the parent window and asks a user to first...

Working with forms and dialogs

The goal for this iteration is to implement the functionality of the File menu options: Open, Save, and Save As.

We can implement these dialogs by using the standard Tkinter widgets. However, since these are so commonly used, a specific Tkinter module called filedialog has been included in the standard Tkinter distribution.

Here's an example of a typical filedialog:

Tkinter defines the following common use cases for filedialogs:

Functions Description
askopenfile This returns the opened file object
askopenfilename This returns the filename string, not the opened file object
askopenfilenames This returns a list of filenames
askopenfiles This returns a list of open file objects or an empty list if
Cancel is selected
asksaveasfile This asks for a filename to save as and returns the opened
file object
asksaveasfilename This asks for...

Working with message boxes

Now, let's complete the code for the About and Help menus. The functionality is simple. When a user clicks on the Help or About menu, a message window pops up and waits for the user to respond by clicking on a button. Though we can easily code new Toplevel windows to show the About and Help messages, we will instead use a module called messagebox to achieve this functionality.

The messagebox module provides ready-made message boxes to display a wide variety of messages in applications. The functions available through this module include showinfo, showwarning, showerror, askquestion, askokcancel, askyesno, askyesnocancel, and askretrycancel, as shown in the following screenshot:

To use this module, we simply import it into the current namespace by using the following command:

import tkinter.messagebox 

A demonstration of the commonly used functions...

The icons toolbar and View menu functions

In this iteration, we will add the following functionalities to the text editor:

  • Showing shortcut icons on the toolbar
  • Displaying line numbers
  • Highlighting the current line
  • Changing the color theme of the editor

Let's start with a simple task first. In this step, we will add shortcut icons to the toolbar, as shown in the following screenshot:

You may recall that we have already created a frame to hold these icons. Let's add these icons now.

While adding these icons, we have followed a convention. The icons have been named exactly the same as the corresponding function that handles them. Following this convention has enabled us to loop through a list, simultaneously apply the icon image to each button, and add the command callback from within the loop. All the icons have been placed in the icons folder.

The following code adds...

Displaying line numbers

Let's work toward showing line numbers to the left of the Text widget. This will require us to tweak the code in various places. So, before we start coding, let's look at what we are trying to achieve.

The View menu has a menu item that allows users to choose whether to Show Line Number. We only want to show line numbers if the option is selected, as shown in the following screenshot:

If the option is selected, we need to display line numbers in the left frame that we created earlier.

The line number should update every time a user enters a new line, deletes a line, cuts or pastes line text, performs an undo or a redo operation, opens an existing file, or clicks on the New menu item. In short, the line number should be updated after every activity results in a change of content. Therefore, we need to define a function called on_content_changed...

Adding the cursor information bar

The cursor information bar is simply a small label at the bottom-right corner of the Text widget that displays the current position of the cursor, as shown in the following screenshot:

The user can choose to show/hide this info bar from the View menu (2.11.py).

Begin by creating a Label widget within the Text widget and pack it in the bottom-right corner, as follows:

cursor_info_bar = Label(content_text, text='Line: 1 | Column: 1')
cursor_info_bar.pack(expand=NO, fill=None, side=RIGHT, anchor='se')

In many ways, this is similar to displaying line numbers. Here, too, the positions must be calculated after every keystroke, after events such as cut, paste, undo, redo, new, and open, or activities that lead to a change in cursor positions. Because this too needs to be updated for all the changed content, for every keystroke, we...

Adding themes

You may recall that, while defining the Themes menu, we defined a color scheme dictionary containing the name and hexadecimal color codes as a key-value pair, as follows:

color_schemes = {
'Default': '#000000.#FFFFFF',
'Greygarious':'#83406A.#D1D4D1',
'Aquamarine': '#5B8340.#D1E7E0',
'Bold Beige': '#4B4620.#FFF0E1',
'Cobalt Blue':'#ffffBB.#3333aa',
'Olive Green': '#D1E7E0.#5B8340',
'Night Mode': '#FFFFFF.#000000',
}

The theme choice menu has already been defined. Let's add a callback command to handle the selected menu (2.12.py):

themes_menu.add_radiobutton(label=k, variable=theme_choice, command=change_theme).

Finally, let's define the change_theme function to handle the changing of themes, as follows:

def change_theme(event...

Creating a context/pop-up menu

Let's complete the editor in this final iteration by adding a contextual menu to the editor (2.12.py), as shown in the following screenshot:

The menu that pops up on a right-click at the location of the cursor is called the context menu or the pop-up menu.

Let's code this feature in the text editor. First, define the context menu, as follows:

popup_menu = Menu(content_text)
for i in ('cut', 'copy', 'paste', 'undo', 'redo'):
cmd = eval(i)
popup_menu.add_command(label=i, compound='left', command=cmd)
popup_menu.add_separator()
popup_menu.add_command(label='Select All',underline=7, command=select_all)

Then, bind the right-click of a mouse with a callback named show_popup_menu, as follows:

content_text.bind('<Button-3>', show_popup_menu)

Finally...

Summary

In this chapter, we covered the following points:

  • We completed coding the editor in twelve iterations. We started by placing all the widgets on the Toplevel window.
  • We then leveraged some built-in features of the Text widget to code some functionality.
  • We learned the important concepts of indexing and tagging.
  • We also saw how to use the filedialog and messagebox modules to quickly code some common features in programs.

Congratulations! You completed coding your text editor. In the next chapter, we will make a programmable drum machine.

QA section

Here are a few questions to reflect upon:

  • What's the difference between the Checkbutton menu item and the Radio button menu item?
  • What's the Cascade menu button used for?
  • Identify different kinds of Toplevel window.
  • List the different types of filedialogs and message boxes available in Tkinter.
  • We used the pack geometry manager to build this text editor. Could we have built this using the grid geometry manager? How would the grid geometry manager fare against pack?
  • How can we trigger events without an external stimulus in Tkinter?
  • What are accelerator options in menu items?
  • What is a transient window?

Further reading

The source code for the filedialog module can be found within the Tkinter source code in a separate file named filedialog.py. You are encouraged to take a look at its implementation.

If you are feeling adventurous and want to further explore the Text Editor program, I encourage you to have a look at the source code for Python's built-in editor named IDLE, which is written in Tkinter. The source code for IDLE can be found in your local Python library directory in a folder called idlelib. On Linux Mint, this is located at /usr/lib/python3.4/idlelib.

Read the official Python styling guide, which is specified in the PEP8 documentation at https://www.python.org/dev/peps/pep-0008.

If you like, try to implement syntax highlighting of Python code in the text editor. A naive implementation would first involve defining a list of keywords. Then we can bind the <KeyRelease...

I haven't even bought this book yet, but ALREADY it has fixed a problem with Tkinter for me. I was trying to change the color of text in a Label widget, but I couldn't find any way to do it no matter what I tried, and furthermore NO ONE could tell me how to do it, NO ONE. Oh, there was LOTS of advice, with "working" code examples, NONE of which worked. Finally, I just happened to skim through the "Look Inside" for this book, and LO AND BEHOLD, the author explains simply and concisely, what I was doing wrong and how to do it correctly. Admittedly I'm a beginner with Tkinter and Python itself, but still, no one could tell me what was wrong until I found this book.

The kindle version is a reasonable price but the paper one is overpriced imho. Takes you stepwise through tkinter functionality with explanations. With the source download you can play around with every example. It's good to have a unified source of information but I still need to Google specific questions. There are a variety of applications, again built stepwise. I have not had time yet to look deeply into these but I believe dipping into them shows you how to do more. I do have a minor criticism that there is a lot of time spent using the 'pack' geometry manager and then immediately after and in one exercise only the author says you should better use 'grid'. My experiments show that tkinter does not allow you to mix these two methods. Perhaps it would have been better from the very start to use grid? Overall glad I bought it but don't ignore video channels like codemy...

Bought this book from Amazon. Although I am a registered customer from the PacktPub publisher, I am unable to download, or even request that they send me the example code files.I can access their website with my credentials and browse through it. However, when I try to send a message to customer service that their instructions are not working for me , I get a response that my CREDENTIALS COULD BE AUTHENTICATED. Other buyers are complaining that is publisher is unethical. If I don't get the example files I will file a complaint against them with Amazon. Thank you.
