To-Do App

This is a simple to-do app that allows you to add, delete, and mark tasks as complete. It is built using Python and CustomTkinter.

At this point in the project, scrolling via the scrollwheel may only work on Linux, due to how TKinter implements the button events differently on Linux/MacOS and Windows. You can still scroll via the scrollbars that show on screen.

Structure

This app is divided into one main service, and 4 other microservices. All communication is done using ZeroMQ.

Main Service

This is the UI of the app, and it is built using CustomTkinter. It is responsible for displaying the tasks, and handling user input. It is built using a system of classes to manage the data and UI effectively. For my own convenience when coding, I am using a pycharm plugin called BetterHighlights, that allows me to link between comments.

Specifically, I used this to link between different commented diagrams of the layout of different TKinter components, as you can see below the Client.build_initial_ui()

def build_initial_ui(self):
    """TODO:Build containers, task list, details, and help page"""
    # tkLayout
    #  root
    #  > menu_bar [[menu_bar]]
    #  > task_container [[task_container]]
    #  > detail_container [[detail_container]]

# ... Later in the  Client class

def build_task_list_container(self): # Client.build_task_list_container
    # tkLayout
    #  task_container #[[task_container]]
    #  > left_canvas
    #    > task_list_container
    #      > button[] [[button]]
    #  > left_scrollbar
        
# ... In the Task class

def build_list_item(self, parent) -> dict: # Task.build_list_item
    # tkLayout
    #  button #[[button]]
    #  > name
    #  > filler
    #  > attributes

Class Diagram

Below is a class diagram of the main service, showing the different classes and their relationships.

Microservice A

This was built by a teammate, and was made to generate different themes that can be used for the app. It is made using Node.js.

Microservice B

This is the server for the app, and where all the data is stored. It has a crude version of https requests implemented, tailored to the purposes of the app.

Microservice C

This microservice allows you to filter and sort different tasks based on their properties.

Microservice D

This microservice is responsible for sending notifications to the user when a task is due.
