Developing Apps with Tkinter: Tree View Operations & Login and Sign-up Pages

Displaying data using a tree view is useful but even more useful are interactive tree views which perform actions in response to user inputs such the selection of an item or a double-click on an item. Financial data is usually sensitive so login and sign-up pages are great ways to authenticate a user of an app. Begin this course by adding an item-selection event handler to a tree view and create a similar stub handler for the double click. Discover how to modularize your code into different code files. After the modularization confirm that the app is still functional. Then you will add login and sign-up pages to the app. Finally you will make an important change to the app by equipping it to figure out the schema of the relevant database table on the fly by referencing schema and metadata information. After completing this course you will know how the tree view reacts to user actions make the tree view robust to changes in the database schema and add register and sign-in functionality to support authenticated data access.
