Updating a text box next to a slider(s) - multiple sliders each with their own text box

MIT App Inventor Help

I am looking to place a label, slider and a text box in a horizontal arrangement
and then duplicate this about 10 times.

When the user moves a slider the value is displayed in the corresponding text box.

I can get the component -- it shows up as
com.google.appinventor.components.runtime.slider@c97d8a1 ( or similar)

I would like to get the name of the slider and then programmatically update the text field next to it.

As an aside is there a way to programmatically do this for a list of sliders with text names

Cotton - sliderCotton - textboxCotton
Silk - sliderSilk - textboxSilk
...
Polyester - sliderPolyester - textboxPolyester

a change to a component using anycomponent does not allow me to get to the exact component.

Thanks

A question though...

Since my list is long (about 20 items -- for 20 different content items

Here is my list ....

Acrylic,Burlap/Jute,Cotton,Flax ,Fur,Hemp,Leather,Linen,Mohair ,Nylon ,Olefin ,Polyacrylic ,Polyester ,Polypropylene ,Rayon ,Silk ,Vinyl ,Viscose ,Wool ,Wood ,Metal ,Glass ,Plastic

Is there a way to automatically create the blocks designer blocks in the horizontal arrangement and name the labels , sliders and textboxes and then create the initialize global (sliders and textboxes). instead of having to create the code every time a new content item is added to the list.

This is exciting! Thank you for your help.

what I had meant in the previous post as either a list or even better a file or even better an sql read from a database..

Thanks

How about a single slider for data entry, reused against the current Selection from a ListView populated with the keys of a dictionary mapping material names into their numeric values?

If you need a comparative display, use a bar graph.

Using the CompCreator extension, you create your view dynamically, and populate it with data from a list or file.

Dumb question....

How does one go thru the list of the Horizontal Arrangements and get at the value of the text boxes.

I tried to use the get value but the VisibleComponent HorizontalArrangement would not connect to the connect box.

Basically I would like to get a list (or similar) of the
values that was selected

Thanks

Not a dumb question :slight_smile:

I attach a revised aia, that provides a button to return each substance and value in a list of lists (for visual appeal, displayed in a label)

You should have noticed that I am applying random values for each substance on Generate. A list of values would be required if specific values are required.
