Now, let's focus to our main topic.

To Add this menu in tkinter text widget, first we will create a simple menu object in which we will add our all options buttons like copy, cut , paste and select all. And Then, we will bind that menu object with mouse right side button click to show menu under the cursor.

Simple!

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

Now, let's do some practical codings.

from Graphics import Tkinter

class Popup:
 def __init__(self, text):
  self.text = text
  self.functions_binding_key()
  self.functions_configurations()

 def functions_configurations(self):
  self.menu = Tkinter.Menu(self.text.master)
  self.menu.add_command(label="Copy", command=self.text.storeobj['Copy'])
  self.menu.add_command(label="Cut", command=self.text.storeobj['Cut'])
  self.menu.add_command(label="Paste", command=self.text.storeobj['Paste'])
  self.menu.add_separator()
  self.menu.add_command(label="Select All", command=self.text.storeobj['SelectAll'])
  self.menu.add_separator()
  return

 def functions_binding_key(self):
  self.text.bind("<Button-3>",self.show_menu_)

  return

 def show_menu_(self, event):
  self.menu.tk_popup(event.x, event.y)
  
  return

if __name__ == '__main__':
 root = Tkinter.Tk()
 text = Tkinter.Text()
 text.pack()
 text.storeobj={'SelectAll':None,
 "Copy":None,
 "Cut":None,
 "Paste":None}
 Popup(text)
 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 ( 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 "PopupMenu.py" In Our "MagicStick/magicsticklibs" Project Directory.



Then Our MagicStick Project Directory Structure will look like this.



MagicStick_Editor_Part_5
 |
 |---> About.txt  
 |
 |---> magicsticklibs
 |  |
 |  |---> __init__.py
 |  |     
 |  |---> Main.py
 |  |            
 |  |---> TextPad.py
 |  |
 |  |---> Graphics.py
 |  |
 |  |---> ConfigSettings.py 
 |  |
 |  |---> ScrollBar.py
 |  |
 |  |---> LineNumber.py
 |  |
 |  |---> StationeryFunctions.py
 |  |
 |  |---> PopupMenu.py
 |
 |
 |---> main.py

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

from LineNumber import LineMain
from ScrollBar import Scrollbar
from StationeryFunctions import StationeryFunctions
from PopupMenu import Popup

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


 def modules_connections(self):
  LineMain(self.pad)
  Scrollbar(self.pad)
  StationeryFunctions(self.pad)
  Popup(self.pad)
  return


Boom! Our PopupMenu.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 "PopupMenu.py".
