‘end’ event not firing when updating the slider programatically #930

Comments

somebeaver commented Nov 28, 2018

When updating the value of a slider handle programatically, the ‘end’ event does not fire.

Example: https://jsfiddle.net/93em1vud/2/ (drag the slider handle first to see the alert(), then click the text)

I see that this method has a second argument, a boolean for firing the ‘set’ event. I’ve tried this, and while it does function as intended, I can’t use it for my purposes. In my specific use case, certain variables are not accessible to me during ‘set’ but are during ‘end’.

So, as far as I can tell, I cannot trigger the ‘end’ event programatically which seems like a bug to me. If I am mistaken then I apologize in advance 🙂

The set event should work for the case you describe, unless I’m missing some important details about your situation. end is fired immediately after set , so could you elaborate on:

«[. ] are not accessible to me during ‘set’ but are during ‘end’.»

One thing in your example is that you are passing a one-value array to a two-handle slider, firing set for both handles. If you set the other value to null , you’ll get one set event:

Thanks for the reply.

I left out some details about my particular implementation of noUiSlider because they weren’t relevant to the issue. Basically I am using custom tooltips that I inject on the ‘slide’ event, and the tooltips avoid each other while sliding around by measuring the distance between each other.

The reason that I needed ‘end’ rather than ‘set’ is because ‘set’ fires before the animations. I modified the original example to demonstrate this here:

I am not sure if ‘set’ should fire before or after animations when used programatically, but regardless, I can’t find a way to reliably calculate the distance between handles (or, my custom tooltips) after all animations have finished.

So that’s why I went looking for ‘end’, and when I found it wasn’t being fired, submitted this bug.

At this point I am not sure if you consider any of this a bug, but I think that having a sort of ‘afterAnimations’ event would be useful and perhaps this is more of a feature request.

How To Get Event Slider Using Shortcode?

There are two different methods to display the Event Slider on the website.

• adaptiveheight: If set to true, The sliders height will auto adjust according to the banner image, if set to false, the height will keep stagnant irrespective of banner size.
• autoplay: Set it to true, to autoplay the events on the slider. Set it to false if you want to manually navigate the events.
• autoplay_speed: [event_slider autoplay=”true” autoplay_speed=”300″] This will decide at what speed the autoplay of events should work. You can set it according to your needs.

How To Get Slider Using Page Template?

1. Create a new .php file into the root folder of your theme
2. Name it something along the lines of “wpem-slider-template.php”
3. Add below code into the file and save.

Now, go to WP-admin >> Pages >> Add New. Here, you will get “Slider Template” option for Template under “Page Attributes” section at right bottom side of the page. Select that template and publish the page. That’s it! 🙂

For more clarification, see this screenshot:

Frontend view Of The Slider

This is how your slider will look on the front end of your website with the event image, event title, organizer name, and organizer description.

Responsive View Of Slider

Yes, the slider you see here is,b>totally responsive. When your visitors are viewing the website on any of the different devices(tablet, mobile, iPad, etc.), the slider promises to render well without messing up the looks and format of your website.

Advanced: Overriding/Customizing the Template Files

For overriding or customization, template files can be found in the wp-event-manager-sliders/templates/ directory. To override a template file,

1. 1. Create directory “wp-event-manager-sliders” under your theme folder
   2. Copy the template file to “/wp-content/yourtheme/wp-event-manager-sliders/” directory.
   3. Your theme will use all the template files from the “/wp-content/yourtheme/wp-event-manager-sliders/” directory instead of the plugin’s template file (/wp-content/plugins/wp-event-manager-sliders/).
      • wp-event-slider.php – which display event listings with slider.

Remember: If you have overridden template file and plugin frequently updating then you need to sync template file with new updates from the plugin’s template file for better functionality and new features.

Application.SlideShowNextSlide event (PowerPoint)

Occurs immediately before the transition to the next slide. For the first slide, occurs immediately after the SlideShowBegin event.

Syntax

expression. SlideShowNextSlide (Wn)

expression An expression that returns an Application object.

Parameters

Name	Required/Optional	Data type	Description
Wn	Required	SlideShowWindow	The active slide show window.

Remarks

For information about using events with the Application object, see How to: Use Events with the Application Object.

Example

This example determines the slide position for the slide following the SlideShowNextSlide event. If the next slide is slide three, the example changes the type of pointer to a pen and the pen color to red.

This example sets a global counter variable to zero. Then it calculates the number of shapes on the slide following this event, determines which shapes have animation, and fills a global array with the animation order and the number of each shape.

The array created in this example is also used in the SlideShowNextBuild event example.

How do I listen to UWP Xaml Slider manipulation start/end events?

What events should I listen to on a UWP Xaml Slider to determine when the user begins and ends manipulation.

This functionality is important when you have a slider that represents some continuously changing app state (say, an animation time) and you want to pause the update when the user interacts with the slider.

This question has been answered for WPF and Windows Phone, but not UWP. The other solutions do not work, or are incomplete, for UWP.

1 Answer 1

You need to listen to interaction events from a couple of the elements of the Slider template: the Thumb, and the Container. This is because the user can manipulate the thumb directly by clicking and dragging it, but also they can click anywhere on the slider and the thumb will jump to that location (even though it looks like you are then manipulating the Thumb, actually the thumb is just being relocated every time the mouse moves — you are still interacting with the container).

There are a couple caveats:

the thumb and container both process their input events and do not pass them on, so you need to use the AddHandler method of attaching RoutedEvent handlers so that you get events which have already been processed.

you need to attach the event handlers after the control template has been applied, which means you need to subclass the Slider to override a protected method.

The following SliderEx class adds some events which can be used to detect when the user begins/ends interacting with the slider:
