4 Spinner

[Verona Garrott]

Centrifuges that accept microplates are typically larger units that take up valuable space on the laboratory bench. The unique design of the Mini Plate Spinner results in a compact centrifuge that has an extremely small footprint - just 6 x 6 inches. Two standard microplates are loaded through a slot in the top of the centrifuge unit. Sealed plates are loaded vertically - surface tension keeps samples in place so there is no danger of spilling samples.

Upon closing the lid of the unit, the rotor quickly accelerates the microplates to 2,500 rpm. Pressing the open button engages the brake and brings the rotor to a stop. For temperature sensitive applications, the Plate spinner may be used in a cold room.

Hi!
I use the spinner where I can choose differnt items.
But always when I open the spinner the first is already selected.
Is there a solution that no item is selected.
Maybe it is possible to use only a text or heading for the first item which can not select.
example:

Hope somebody can help me.
kindly regards

Nothing in Prompt
Heading is first item in List
Selection Index set to 1
(Nothing will happen if the user selects item 1, the spinner just closes)
After selecting you need to reset selection.index to 1

For example, in one of the points I have "Select time" and everything is fine the first time I call the Spinner from the button, but when I want to select the time again without changing the screen, the selection remains on "Select time" and that's it. I can't get the clock to toss me again

The app I'm creating is a task app and I have a spinner for the user to select a specific action like delete the task. After the user is done selecting the thing they want, I want the selection to automatically be "Options" again.

Having a selection that essentially should not be selected is bad practise! Your spinner should be set to the most common/likely choice. The component makes it obvious there are other options by design.

I usually call a spinner from a button, setting the spinner height and width to 1x1 pixels to effectively hide it (the spinner must be visible in order for it to work) I then set my title/default/non-working element which is the first element, no action is taken if this is selected, and makes your real elements available for selection.

Are you accessing the published survey from the Survey123 web app or from the field app? And have you updated either Connect or the Survey123 field app since you tried it last time? If you send your XLS form, I can see if I run into the same issue.

Thanks for including that image. In the screen cap on the right it looks like you're viewing the published survey in the web app. Unfortunately the spinner and numbers appearances are not supported on the web app. I just published an Appearances sample and it looks like those two appearances are working as they should be in the Connect preview and in the field app.

If you are looking to access your published forms from the web, the Appearances tab in any Advanced Template or Sample XLS form has a list of which appearances are supported by the web app and which are supported by the field app (this list was added recently, so it will only show up on XLS forms created after July 23).

I am having issues with all the spinners where the values increase or decrease in seemingly arbitrary values. System units are set to feet, display units to cm with 3 decimal places. Spinner snap does affect this, regardless of the precision it is set to (1-0.01), it only changes the increment size, but does not resolve the arbitrariness. I am using 3ds Max 2020.1.

Hi @Intuos5 Are they incrementing by what you would consider large values? Does it happen when wrapping around upper and lower screen borders? We have a known issue that we believe to have a potential resolution for, current testing in our beta program. If you think this sounds like the same issue, I invite you to check out our beta program and help accelerate the testing so that we can get this out in a public release as soon as possible.

Hi @brentscannell, I am certainly not trying to increment by large values, I was hoping to get something like 1 cm or 1 mm increment by using the spinner snap toggle. The spinner snap toggle behaves the way it should when modifying values of an object, however, it does not do so when clicking on spinner arrows nor when using the extrude caddy. There may well be more functions misbehaving, because the same happens with the bevel function on both the height and outline spinners.

I've attached a screen recording in the hopes of making things more clear. Note that the initial action on the spinners increments a weird value, but that later adjustments occur on whole centimeters.

I think I understand what's going on: the increment value is using the system unit rather display unit, and my hunch is that you have your system units set to "feet". Each time you increment, you are adding 1 foot (30.48cm).

The click and drag behaviors is a bit different though and I don't believe respects the snap setting. The way they increment while dragging is a bit different between different tools/spinners in 3ds Max, but for the most part they scale the current value, meaning if you start with a 2000cm value, it won't increment the values 1cm at a time while dragging. We are aware of this particular inconsistency and are discussing internally about what the optimal behavior ought to be in these cases.

Correct, that's for Revit interoperability. Upon changing the system units, there remains a problem, so I've attached another video, which I hope will be useful to you. What I am seeing is that once the arrows were used to change a type-in result, the spinner behavior no longer adheres to the increment it was set to. This is the case for all spinners as it seems.

My personal preference, now that I am aware of the inconsistency between spinner and arrow, would be to set a spinner and spinner arrow increment in the preferences. For example, have the arrow increment set to 10m and have the spinner increment per cm, so best of both worlds, hit the arrow for large values and adjust by spinner, rather than having to cover it all by spinner. It would allow for reduced mouse movement. Besides, user preferences may vary and could be covered by a preference setting.

As far as click and drag spinner manipulation, there's no doubt that we have some work to do here. It wouldn't be fair to tag this as a single bug or something as simple as that. I appreciate your input on this topic, and while we don't have any immediate plans to start working on spinners, I do think that this is an excellent research candidate to start formulating a development plan for. Have you checked out our ideas forum?

I don't recall off the top of my head if a similar feature improvement has been proposed, but this could be an excellent place to log this idea and start some discussions about ideal spinner behavior. May I ask you to see if an idea is already started that resembles this topic, and to start a new one if you don't find something fitting?

Great, this worked! I did not want to limit the number that can be entered, so I only entered .>=0, which works fine for what I need. It still allows the spinner to go into negative numbers, but as you mentioned the form can't be submitted until that is corrected, so that will work fine. Thank you!

Regarded as one of the most acrobatic of dolphins, spinner dolphins are well known for their habit of leaping from the water and spinning up to seven times in the air before falling back into the water. Experts believe that spinner dolphins use these behaviors primarily for acoustic signaling or communication, but the activity can also be a way to remove ectoparasites, such as remoras.

Individual dolphins are identified by their unique dorsal fins. Researchers take photographs of the dolphins' dorsal fins and then match the shape, nicks, and notches in each fin to a catalog of known individuals to obtain life history information for each animal.

Spinner dolphins feed at night on species including small fish, shrimp, and squid that are found about 650 to 1,000 feet below the surface of the water. Spinner dolphin prey species follow a vertical and horizontal migration pattern, staying in deep waters in the ocean during the day, and then moving up in the water column (vertical migration) and inshore (horizontal migration) at night. Spinner dolphins take advantage of the nightly migration that brings their prey species to shallower depths and closer to shore by feeding throughout the night.

When resting, spinner dolphins move back and forth slowly as a single unit, with the animals in tight formation but spaced just out of contact with one another. They may engage in resting behaviors for about four to five hours daily. This behavior may vary seasonally, coinciding with the shifts in day length. During rest, spinner dolphins rely on vision rather than echolocation for scanning their environment. Group movements during rest are typically in open, sandy-bottom areas where predators are more visible.
