PyQt example of QTreeWidget which is editable

Intuitive enough to use, but this is for example only

• PyQt5 >= 5.8

• git clone ~

• Show the exmaple of adding & deleting the tree widget item in convinient way
• Support multiple options:
  • make it unable to edit the parent item's name which has the child
  • user can make the certain item not editable
• Convert QTreeWidget hierarchy into JSON format
  • convert the QTreeWidget hierarchy into JSON format (in Python, array of Python dictionary) to save in "tree.json"
  • Load the saved JSON content from "tree.json" and convert it into QTreeWidget when user executes the window again

The each object of tree.json contains multiple properties - name of the item(name), editable flag(editable), childs of the item(data)

Key command

• Enter/Return - Add new child
• F2 - Rename attribute
• Delete - Remove attribute
• Up/Down - Previous/next attribute
• Shift+Up/Down - Go parent/child attribute

Context Menu

• Add parent attribute
• Add child attribute
• Rename - rename the item
• Editable - check to make the item editable or not
