Inputs and Outputs are not updating manually in Human UI

[zohaibneduet]

Hi all, I have created a simple Human UI to calculate volume as output from three input sliders but unfortunately I am not able to manipulate sliders in Human UI, that is the first issue.

The second issue is, “Add Element” Component is Organe colored but I do not know why?

Can anyone help me with these issues? The screenshots and file are attached here.

Thanks

If you read the error message on the add elements component, you’ll see you’ve broken the first rule of Human UI: Don’t hook the output of a value listener into the input of a “Create” component. (even indirectly). Please review the example files here: Example Files

Every Human UI definition has the following parts:

1. “Create” components, which initialize a UI element
2. “Create Window” + “Add Elements” to instantiate the window and put UI controls in it
3. "Value Listener"s to get values out of the interactive elements in the UI
4. “Set” components, which can modify or update a UI element you already created.

Your problem (a common one!) is that you’re trying to do #4 with #1. Try initializing the “volume” readout with an empty / dummy value first and setting the actual volume value with a corresponding “Set” component.

HumanUI DataTable crash

if you understand the create/set model in Human UI - (Golden rule: Never make a create component downstream from a value listener) then you can safely disable it. All it does is warn when you violate that. But I would say 90% of people’s mistakes/issues with Human UI come from misunderstanding this rule. (I take credit for this problem - if I were to design Human UI today I would set it up in such a way that this was a non-issue, but alas.) The reason it is possible to disable the checker is tha…

HUMAN UI dynamically defined dropdowns

the golden rule of human ui is no input to a create component changes after the window opens. Populate the pulldown menu with static dummy data first then use “Set List Contents” to update it.

Toggle On/Off resets HUI Window to Tab1

This usually indicates that you’ve violated the golden rule of Human UI — to never change the inputs of a “create” component once the window is open. Is the “Add Elements” component orange?

@andheum: Is that what you are saying?

@andheum: I am also trying to mention Maximum Value (Range) at the end of the slider and the current value at any point above the slider, How can I do that? the screenshot indicates the positions of these values.

Also, instead of being updated automatically when the inputs are changes, I want to place a button to update the output manually after manipulating the inputs. Is it possible?

Please guide me with my problems, I will be very much thankful to you!

@andheum: I have resoled the issue about the Max Value and Current Value of Sliders, Can you please help me in manually updating the output?

Here is a good strategy:

Human UI: Single button for all the inputs

There’s a pattern for these situations that I like. The value listener on your text inputs is set to “manual input” (disable “Live” in the right-click menu) and triggered with a “live” value listener on an update button (Should probably be a “true only button” so it only fires once per click). It’s easier shown than described: [trigger-button] commit-button.gh (10.0 KB)

Thanks @andheum, It worked. Can you please help me with this problem?

Hi all, I am trying to display results of multiplication of a long list with a number. But at the output, it is only displaying one value. Why is that?
