hii readers,




Fonts are Normal Text Characters use for Representing Text Data. Font provide us different visual style for representing our text character in Text Editor. So, Today In This Post, I am Going To Show you how to create automatic font selecting dialog box that can configure Tkinter Text Widget Font Options Automatically.

Or You Can Also Download Our Updated Example Codes Of Python MagicStick Text Editor Project For Understanding This Project More Clearly.

Check Here Our Github Repo


Now, let's focus to our main topic.

For this purpose we will use tkFont module. This Module Provide us ability of doing changes in Tkinter Text Widget Automatically. This Module works like a Automatic Interface between Tkinter Text Editor Font Options and The Usee. In Simple Words, This module is also very easy, compitable and stable for changing Tkinter Text Widget Font Options.



To make this script easy to understand we will create a separate empty script "FontChooser.py" in "magicsticklibs/" folder and write our codes  in it.

In This Script, First, We Will Create A Simple Class of Tkinter Toplevel Widget. And Then, we will add Our Different Functions and Other Tkinter Widget On it.


So, let's do some practical coding's.

1. FontChooser.py

To Run These Script Codes alone, Just Change line 24,25 from

"from Graphics import Tkinter"
"from Graphics import tkFont, ttk"

To
"import Tkinter"     and
"import tkFont, ttk"

Or

To Run This Codes as MagicStick Script. Don't Do Any Changes in this codes.






 Now, let's join this script in MagicStick Text Editor Project ( Follow Below Steps only, when you have not Connected this script with MagicScript Main Stream).

To Connect This Script With MagicStick project, we need to do only two steps.


1. first, Place This Script In Our "MagicStick/magicsticklibs" Project Directory.


2. Add Function Of This Script in Our "ConfigSettings.py".





Let me explain you these steps in more details.



Step 1.
 Place "FontChooser.py" In Our "MagicStick/magicsticklibs" Project Directory.



Then Our MagicStick Project Directory Structure will look like this.



MagicStick_Editor_Part_11
 |
 |---> About.txt  
 |
 |---> magicsticklibs
 |  |
 |  |---> __init__.py
 |  |     
 |  |---> Main.py
 |  |            
 |  |---> TextPad.py
 |  |
 |  |---> Graphics.py
 |  |
 |  |---> ConfigSettings.py 
 |  |
 |  |---> ScrollBar.py
 |  |
 |  |---> LineNumber.py
 |  |
 |  |---> StationeryFunctions.py
 |  |
 |  |---> PopupMenu.py
 |  |
 |  |---> FindAndReplace.py
 |  |
 |  |---> FileHandler.py
 |  |
 |  |---> FontChooser.py
 |
 |---> main.py

Step 2.
          Add "FontChooser.py" Function in Our "ConfigSettings.py" because in this project, "ConfigSettings.py" is responsible for joining libs in main stream.

Boom! Our FontChooser.py script is now ready to use and also, this script is now connected with MagicStick Project Main stream. To run this script in main stream of project. just run "main.py" script or you can also run this script alone and parallel without touching project main stream just run "FontChooser.py".


This Tutorial Ends Here,


In My Next Tutorial, We will Continue This project.
