While toggling all checkboxes is simple enough, I can't wrap my head around giving each group logical v-models to behave reactively.

I'm building a notes taking Vue app.
The note being edited is auto-saved every X secods.
Every time it auto saves, I want to show a small message on the bottom of the screen saying "Note Saved". This will fade in stay for 2 seconds and then fade out automatically.
I've done transitions in Vue before but not on-off transitions like this.
I can set a property linked to the element with v-if wrapped in a transition block. But then I need to change the property twice (true-false)? Would I need to set up a timer to wait the transition to be over before setting it to false again? Seems a bit hackish. What's the best way to approach this?
I think what you've described with v-if makes sense... you could change the property (or data) in a v-on:enter method on the related component. This would nicely isolate the behavior to the component and be pretty apparent to future-self.
A completely different approach would be defining a single animation with keyframes that transitions from hidden to display to hidden, but that might be somewhat confusing: what is the leave transition of an element with such an enter transition? Hmm.
I have a ComboBox with thousands of items bound to it.
The problem I'm facing is when I run the app on a tablet the scrollviewer's scrollbar is very thin hence I cannot hold and drag it and can only swipe to move inside the ComboBox.
Hence I was wondering is there a way to change the style template of the ScrollViewer inside the ComboBox inorder to make the ScrollBar width larger.
You'll have to dig in to the style template and change some hard set properties for Width / Height that sit on the parts like the Thumb that you will find on the default style template. You can extract a copy via selecting a Scrollbar -> Right Click -> Edit Style -> Edit a copy. Save the copy wherever you need it, like a resource dictionary if you plan to use it multiple places or to the instance where you need it.
(Note: Generally folks start at the ScrollViewer level, then find a Scrollbar in it, and apply the style changes there so they can apply the style directly to ScrollViewers)
Once you have your changes made to the control template you then need to pass them to your ComboBox. If you only need it for the one ComboBox, You can just put the style template in it's Resources and remove the x:Key name you gave it so it hits the instance of the TargetType via inheritance for just that ComboBox.
However if you want it to hit EVERY ComboBox, then you'll need to edit the ComboBox style template and add a reference to the Style template you just made to it's embedded ScrollViewer.
You'll find long tutorials out there for stuff like WPF/Silverlight that pretty much the same concept but little nuance differences in the templates and syntax of properties.
Hope this helps, give it a shot and if you get stuck come on back and we'll get you sorted.
If you nest swiper instances and don't set the nested swipers to move in a different direction (as the demo does) then they seem to got mixed up on which one should be advanced when you swipe to next/prev.
UPDATE: This only happens when you use a trackpad - if you use a mouse it seems to work fine.
Codepen Example
So in my example I have set up a swiper with a cube effect and it then has four nested swiper instances, each with 3 slides. The nested instances have the default slide effect and have their nested options set to true.
So the desired effect is that you see the cube with an 'A' facing you, you then swipe to next and 'B' slides in, then the next wipe rotates the cube and you see 'C' on a different side - and so on.
This works most of the time, but every so often when you expect the nested slider to advance the parent slider does. So in my example you see the cube spin when it shouldn't.
I've tried to use javascript to lock the swipers when the swipe begins and then unlock when it ends but that didn't fix the problem.
i worry that my xcode vocabulary is insufficient here -
in Interface Builder,
i frequently would like to use the precise element-selection of the hierarchical element list, and then switch to jogging the position/size of the elements with the arrow keys.
the only way i know to do this is to carefully click on one of the drag-boxes revealed around an element when it's selected, which shifts keyboard focus from the element list into the visual layout. but this is difficult and error-prone because it's easy to accidentally move the element a bit, or the drag-box may be underneath another element, or you may have multiple elements selected, etc, so a hotkey of some sort would be ideal.
apologies for not having the right names for all the things here.
even the names would probably help me search.
A: obvious but i missed it - double-click the element in the hierarchy. it would be nice if there were a keyboard command to do this, but i'll settle for the double-click.
Is there a way to link two indicators on a LabVIEW front panel, so that they always have the same value? Right now I'm setting both to the same value every time, but it'd be much easier if there were a way to set up one to mirror the other.
You can make the digital display visible. Right-click on the slider and select "Digital Display" from Visible Items.
There are a few ways to achieve this, depending on how you are trying to display the data.
If you are just trying to update a slider and make a textbox indicator display the numeric value then by right clicking on the slider and selecting 'Visiable Items -> Digital Display' you will have a numeric indicator showing the value of the slider. This can then be repositioned as required. You should see if this meets your requirements as other methods will add complexity to your Block Diagram.
An alternate method would be using a network shared variable and binding the data although I think from your question this would be over kill.
You can also create an event structure to look for a value change event for the slider and update the text indicator accordingly. You would have to be careful how you update the slider as just wiring a value to the slider will not trigger an event for use a property node linked to the slider for the property 'value(signalling)'. Again this may be over the top for your application.
Strictly speaking, no, you can't do that automatically. What you can do is set up an Event Structure and use the Value Changed events for each of the two controls to update the other. Just realize that the slider fires value changed events many times while the user is sliding it around, rather than just one event at the end. That may be what you want in this situation, however.
I think this is not easily done, however there are some possibilities (as discussed).
The general question is why?
You have an indicator with the same info at two places. (or are they actual controls?)
If you have two indicators, just place there terminals next to each other, just remember when you alter one of the two (via a local or by ref) to mimic the action for it's twin.
Using a value change event for both controls should work, just remember that you might get race conditions if you don't process the event directly.
Could describe a little bit further why you need two controls for the same action/value?
