Now, let's focus to our main topic.

Here, For Handling This Types Of Feature we will create a separate file called  "StationetyFunctions.py". This Script Will Works like a special script for handling Stationery work.


Check Below my Example Codes.

    pad.pack()
    root.mainloop()



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

"from Graphics import Tkinter"

To  "import Tkinter"

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.

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 "StationeryFunctions.py" In Our "MagicStick/magicsticklibs" Project Directory.


Them Our MagicStick Project Directory Structure will look like this.

 |
 |
 |---> main.py


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

  self.modules_connections()


 def modules_connections(self):
  LineMain(self.pad)
  Scrollbar(self.pad)

  return


Boom! 

Boom! Our StationeyFunctions.py script is now connected with MagicStick Project. To run this script in main stream of project. just run "main.py" script or you can also run this script alone and parallelled without touching project main stream just run ".py".
This Tutorial Ends Here,


In My Next Tutorial, We will Continue This project.
