Interlude: Reactivity and Functions One of our core contributors recently told me, “I didn’t use closures so frequently until I started using Leptos.” This is indeed true. Closures are at the heart of any Leptos application. Sometimes it seems a bit silly: // A signal holds a value and can be updatedlet (count, set_count) = … Read more
With the rapid development of smart devices, embedded GUI development has become a key bridge connecting hardware and user experience. In the face of resource-constrained embedded environments, choosing the right GUI framework not only affects development efficiency but also directly determines the product’s user experience and market competitiveness. Comparison of Three Major Frameworks LVGL – … Read more
A practical guide for engineers: from touch screens to industrial control, from C++ to Qt, Electron, and touch protocols, this article clarifies the core technology selection behind HMI. 1. What is HMI? It’s More Than Just “Touching the Screen”. HMI, short for Human-Machine Interface, can be simply understood as: A device “frontend” that is understandable … Read more
A few days ago, I wrote an article comparing three cross-platform C++ GUI frameworks: Qt, Dear ImGui, and Elements, based on my project experience, discussing their performance and trade-offs in different scenarios. After publishing the article, a reader mentioned in the comments, “Could you also discuss U++?” This suggestion reminded me that while working on … Read more
