Qt or HTML? A Million Dollar Question

In this white paper, Burkhard Stubert explains how he could save one of the world’s largest home appliance manufacturers millions of Euros by choosing Qt over HTML. The secret? Qt scales down to lower-end hardware a lot better, without sacrificing user experience:

With a five times smaller footprint, four to eight times lower RAM requirements and a more efficient rendering flow than HTML, Qt provides faster start-up times and maintains the cherished 60fps and 100ms response time, where HTML would struggle. The calculations show that being able to just downgrade your SoC by just one tier like this, Qt can reduce your hardware costs by over 53%.

Qt QML vs HTML5

A practical comparison by Sequality

One man takes 160 hours to create a demo application of an embedded system using Qt & QML and same number of hours to create the very equivalent application using HTML5. Discover how he compares the two technologies and shared the findings during the evaluation in terms of:

  • Development comparison between HTML5 vs Qt
  • Development experience
  • Performance results
  • Software management and sustainability

What is not mentioned in this whitepaper, is the beauty of  Qt providing freedom to the developer enabling the  creation of hybrid applications with HTML5 and Qt/QML, whereas HTML5 will not have the ability to mix or show Qt based applications. Developers have the flexibility of creating UIs in many ways besides HTML5.

Audience: This whitepaper is intended for developers and tech. managers creating applications for mobile, desktop, embedded and IoT devices.

Driving the User Interface

Motor show concept cars have traditionally attracted attention through outrageous body styling, but today’s advanced demonstrators place at least as much emphasis on high-tech gadgetry inside. Recent appearances by leading car brands have impressed audiences with large touch screens that centralise access to everything from cellphone contacts, multimedia content and social media to navigation, parking assistance and graphical vehicle diagnostics.

Many of the latest mid-range cars have now been launched with a graphical centre-console for navigation, communication and diagnostics, while high-end brands are beginning to offer connected-car applications delivering Internet access and value-added services to their customers. Demands for such innovations are coming from several directions, as car buyers expect improved user experiences, legislators mandate systems aimed at improving road safety, and car makers seek to connect more closely with customers through electronic value-added
services.

Building the Internet of Things

Building the Internet of Things and How Qt Can Help. The term, Internet of Things (or IoT), is everywhere. For people wanting to impress others, it’s the latest buzzword to include in a conversation in order to be seen as relevant. For many developers, the term is just a more fashionable description of the connected embedded system, however IoT adds additional promises to how these devices need to operate. This whitepaper defines what the requirements are for developing IoT software, compares frameworks and describes the advantages of using Qt to develop your IoT solutions.

Learn about IoT:

  • Software Requirements
  • Embedded Development
  • Specific Challenges
  • Big Data
  • Consumer Experience
