Add/remove rows on button press
Joseph Edwards
I am working on a gui that will replace an excel spreadsheet as part of a short workflow to a database. I am aiming to keep a similar format to the spreadsheet with rows of 3 columns:
Number ID
Category (spinner menu)
Text Input
The overall layout of the gui is exactly how I'd like it and I've achieved one row, now I need to work out the functionality of adding duplicate rows.
I want to use the buttons in the bottom left to add and subtract the rows, components of each new row will also need a unique ID so I can use the user input data individually.
I am hoping I haven't been too ambitious with this project as I love the slick look of Kivy and the end result doesn't seem too far away now, but unfortunately I have reached a point that requires a higher skill level than I currently have.
I am working through the Dusty Phillips Kivy book but would love some expert guidance in the meantime to help maintain momentum on the project.
I hope this makes sense and thanks for reading.
