Using list data to update UI Elements?

[DREW_HOLZINGER]

I want the data entered into the text input field to populate a list and show in the labels text. The user can update the info and stats for the hero.

I tired to use an iterating counter to keep track of all indexes of my lists. However I can't 'set' a label's text value from within a list. I can only call it.

What would you do? Some of my students built really long If/then statements to work through the iterations and stop at 8.

TinyDB functions

I took a couple of hours to whip a quick and sloppy TinyDB Contact list app with dictionaries. Here's a video of it at work ... (I used my phone's screen recorder, which unfortunately does not catch cursor actions.) Designer: [Designer] Components include: A list Picker to pick Contacts from a TinyDB TagList A text box to show the current ContactName or enter a new one A Horizontal Arrangement to present a contact Attribute and its value, and allow Enter of a new value A ListV…

This introduces dictionaries, which use names instead of numbers to access items in a collection.

The students' stat names are equivalent to the contact attribute names in my sample.

However I can't 'set' a label's text value from within a list. I can only call it.

The secret to that is to keep a list of the Label component blocks, not the Label.Text blocks., and to use the Generic (Any) blocks to updated the selected Label component.

(The component block is always the last block in the component's Blocks pallette.)

Here are some sample apps that use lists of components:

Wordle In A Day

This week the US news networks have been reporting on a free web game by Josh Wardle called Wordle, similar to Jotto, developed as a personal project and open for all. His variation has: one chance to play per day every one shares the same daily word words have exactly 5 letters you get six guesses You are told which letters match in place (green), which letters match out of place (yellow) which letters don't match anywhere (dark grey). I decided to try to replicate his app in AI2 under t…

Go Scroll Yourself! blocks only (No extensions, No JavaScript)

This tutorial is intended for people who need to display a heavily customized scrollable window into a large table. It can also be used as a CardView. (I needed a pithy title, and "The Elder Scrolls" was taken.) My sample subject area for my data is the historical or current set of legislators in the US Congress, both Representatives and Senators, with photos (where available.)
