Now, let's focus to our main topic.

Here, First We will create a separated script "Scrollbar.py". And In this Script, We will Create a Scrollbar Class That can Add Scrollbar In Text Widget.

'''

from Graphics import Tkinter

class Scrollbar:
 def __init__(self,text):
  self.frame = text.master
  self.text = text
  self.text.configure(wrap='none')
  self.for_x_view()
  self.for_y_view()

 def for_x_view(self):
  # scroll Bar x For width
  scroll_x=Tkinter.Scrollbar(self.frame, orient='horizontal',command=self.text.xview)
  scroll_x.config(command=self.text.xview)
  self.text.configure(xscrollcommand=scroll_x.set)
  scroll_x.pack(side='bottom', fill='x', anchor='w')
  return

 def for_y_view(self):
  # Scroll Bar y For Height
  scroll_y = Tkinter.Scrollbar(self.frame)
  scroll_y.config(command=self.text.yview)
  self.text.configure(yscrollcommand=scroll_y.set)
  scroll_y.pack(side='right', fill='y')  
  return


if __name__ == '__main__':
 root = Tkinter.Tk()
 pad = Tkinter.Text(root,wrap='none')
 Scrollbar(pad)
 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 "Scrollbar.py" In Our "MagicStick/magicsticklibs" Project Directory.


 MagicStick Project Directory Structure.


MagicStick_Editor_Part_2
 |
 |---> About.txt  
 |
 |---> magicsticklibs
 |  |
 |  |---> __init__.py
 |  |     
 |  |---> Main.py
 |  |            
 |  |---> TextPad.py
 |  |
 |  |---> Graphics.py
 |  |
 |               |---> ConfigSettings.py 
 |  |
 |  |---> ScrollBar.py
 |
 |
 |---> main.py


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

'''

from ScrollBar import Scrollbar

class Connect:
 def __init__(self, pad):
  self.pad = pad
  self.modules_connections()


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


Boom! Our Scrollbar.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 "Scrollbar.py".


This Tutorial Ends Here,
In My Next Tutorial, We will Continue This project.
