The next chapterĬontains the predefined dialog boxes that Qt provides for common tasks Widgets, such as push buttons and labels. We also provide guidelines that specify when to use a certain widget. This is why we present widgets that are alreadyĪvailable with their most useful methods in this chapter and in Chapter 5. Qt is a rich library and as a beginner, you could easilyįind yourself reinventing the wheel when a Qt class OverlayWrapper.Chapter 4. A Guided Tour Through the Simple Widgets ("gallery_image-active") Ĭonst imageParentElement = image.parentElement Ĭonst moveTransition = document.createDocumentTransition() Īwait moveTransition.start(() => moveImageToModal(image)) Apply a CSS class that contains the page-transition-tag before animation starts. Let’s see how we can create this animation in just a few lines of JavaScript and CSS.Ĭonst overlayWrapper = document.getElementById("js-overlay") Ĭonst overla圜ontent = document.getElementById("js-overlay-target") Ĭonst image = document.getElementById(`js-gallery-image-$`) ![]() When the expanded image in the overlay is clicked, it will return back into its place. We’ll create an image gallery with the following animation - on card click, the image inside the card will expand and move from its place in the grid into a fixed overlay. Let’s start with a simple and fun example. The API also allows us to tap into those individual states and more and gives us full control over the animation using the standard CSS animation properties. All we have to do is take care of the DOM updates and animation styles. In a nutshell, Shared Element Transitions API allows us to skip a lot of prep work by ensuring that both outgoing and incoming states are visually present at the same time. You also have to handle a handful of edge cases and accessibility issues that might come up as a result of that. If you were using only JavaScript without any libraries or frameworks, you’d have to ensure that both the current and next image are present, and then fade out the current image and fade in the next image simultaneously. Let’s take a simple image carousel that crossfades between the images as an example. Examples will be accompanied by a video, so you can easily follow along with the article if you don’t have the required browser installed.Īnimating between UI states usually requires both the current and the next state to be present at the same time. Shared Element Transitions API is currently supported only in Chrome version 104+ and Canary with the document-transition flag enabled. Browser Support And API StatusĪt the time of this article, API is in its early “Editor’s draft” stage, so the standard is not yet finalized, and the specs might change as time goes on. In this article, we’ll dive deeply into this game-changing API which is still in its early stages, and explore its incredible potential by building four fun and exciting real-life examples from scratch. What if we could just skip all that, use vanilla JavaScript and CSS, and let the optimized browser API do all the heavy lifting while maintaining complete control over how they perform transitions between the various UI states? With the new Shared Element Transitions API, implementing animations like this will become incredibly easy and seamless. In the end, it’s up to the browser to download, parse and execute the animation engine before it’s ready for use. However, JavaScript is the most expensive resource on the web, and these libraries are bundled alongside the content and primary resources. They do a solid job and certainly simplify the process. ![]() ![]() JavaScript libraries like React and Vue probably popped into your mind right away, alongside JavaScript animation libraries like Framer Motion and GSAP.
