Number scrolling animation - xamarin.forms

Scenario:
I wanted to show an animation while increasing or decreasing a number. For ex. Let's say we have 12390 as a counter displayed on the label on the screen if counter increases say by 100; then I want to show upwards scrolling animation to reach the new counter (12490), similarly, I wanted to show downwards scrolling animation if the counter goes down.
How can I achieve it?

How to hide an element after its opacity get equal to 0?

Is it possible to change display of an element to none only when the opacity would be equal to 0?
I have the following code:
<slide class=“showing” :class=“{notshowing:!opened}”
<div> Some text</div>
</slide>
And css
.showing {
display:flex
}
.notshowing {
transition:2s;
opacity:0
}
I have a carousel with too many slides, to get a clear image,e .g.on first slide I have 3 options, if I click on first option it throws me on the second slide(after that I can comeback to the first slide by clicking on the button(carousel is styled that way that user cannot drag it)), second option to third slide etc.
so if I have too many options, it will take me different amount of time to get to different options. I came up only with one solution and it is to track by class the slide which I need(which option user click),hide the others, so that the number of slide for every option would be 1. However,if I instantly set display of slide to none, it would look awful. So that’s why I want to set opacity to 0 with transition when I leave the slide and then hide it

How can i change the speed of listview scrolling in QML?

I have created a list by using listview in QML. In my case, i want to change the speed of the list scrolling, scrollBar and the highlight to different value. For example,
Here is a list. While i move the highlight to the next element, three types of animation will be happened.
scrollBar will scroll to bottom
list will scroll to the top
highlight will scroll to the next element
As i known, i can change the the highlight by
ListView {
highlightMoveDuration : 200
}
I found that three types animations will start at the same time and last for the same time.
But in my case, i want to set three animations to stop at different time.
For example:
ScrollBar: start:0, End:300
List: start:0, End:400
highlight: start:0, End:200
How can i do that. Also, if they start at the different time, how can i do that?

How can I scroll content horizontally with fullcalendar scheduler?

Using a heavily customized version of the scheduler, I'm getting reports that users are having trouble figuring out how to scroll horizontally. I imagine it's because the scrollbar is at the bottom of the schedule and on Mac OS, it's potentially hidden if the user has a trackpad.
My schedule functions similar to this one minus the vertical scroll. If you're on an Apple laptop and only using trackpad it's likely you won't see a scrollbar at all. If the scroll bar is visible, it's buried under the page's fold.
Ideally, I'd have arrows near the times so users could click left or right and that view would scroll left or right. I've been unable to figure out a way to programmatically call $.animate({ scrollLeft: ... }) on any piece of the scheduler and scroll both the contents where events are and the header where times are.
It looks like I can get and set the position of at least the timeline with $( '.fc-time-area .fc-content table' ).offset() but it won't move the contents of the schedule itself.
Any idea how I can move the schedule content (events) and the timeline in sync with each other?
Bonus internet points if you can tell me how I could ensure that I'd only move the container to it's end. (i.e. If the schedule for that day ends at 10pm, don't allow me to change the offset to something beyond 10pm)
Any idea how I can move the schedule content (events) and the timeline in sync with each other?
To get to the beginning of the view:
$('.fc-body .fc-time-area .fc-scroller').scrollLeft(0);
And for scrolling to the end of the view, you can do something as follows:
var scroller = $('.fc-body .fc-time-area .fc-scroller');
var scrollWidth = scroller[0].scrollWidth;
scroller.scrollLeft(scrollWidth);

Layers disappear after a while?

So I'm using Revolution Slider with 1 slide only and the layers on my slide keep disappearing after X minutes even though:
my slide is set to 9 seconds
the slide is set to end on this slide (General Settings -> Pause Slider -> Stop Slider Progress)
all the layers are set to fade after the slide ends so I have no clue what is with this glitch of layers disappearing after a few minutes.
Has anyone experienced something similar?
I reckon your problem will be fixed by following the instructions at https://www.themepunch.com/faq/prevent-layers-from-disappearing/.
To paraphrase those instructions, in the layers timeline section of the slide editor, set the layer to snap to the end of the timeline. The alternative is to set the layer to disappear beforehand which you don't want. This is a simple toggle button under the 'Fade' Column header.

Qt: When is layout "Final"?

I'm having a problem where I cannot deterministically tell when a layout takes place.
Simplified example:
I have a widget with two sub-widgets.
Top widget has expanding width and fixed height. Let's say the fixed height defaults to 50.
Bottom widget has expanding height and width
There's a vertical layout set up.
Let's say there's a button somewhere i can click to run code. The button is not on the widget itself to make things simple...
When the button is clicked, i do the following:
I measure the height of the bottom expandable widget. The height is 100.
I then "topWidget->SetMaximumHeight(100)", and "topWidget->SetMinimumHeight(100)"
I measure the height of the bottom expandable widget again. The height is still 100
But I see the bottom expandable widget change height!
this means that when I do step #3, the layout hasn't taken place yet. No matter what I do, update(), updateGeometry() - I cannot get the bottom widget to change height between step #2 and step #3.
The only way for me to resolve this is to have a timer wait, say 250ms, and then measure the height of the bottom widget -- and then It's always correct - meaning the re-layout took place correctly
This is a crazy/dirty solution, but I don't have another. Is there an API I am missing to allow me to deterministically, synchronously change the layout and query for the new size of affected widgets right after?

Try calling QApplication::processEvents() between steps #2 and #3 (it should do what the timer allow the event loop to do)
