This session shows how to develop applications for multiple screen sizes, screen resolutions and form factors like phones, tablets and desktop PCs with Qt. We show how you can use the same code base, while having native-looking UIs across platforms. This involves tips for responsive design with Qt and a comparison when to use Qt Quick and in which cases C++ is the better choice. This talk will also explain which Qt components you can use to increase your application downloads and user retention. And how to measure the success of your apps across platforms. This presentation gives you a non-technical overview of the possibilities with Qt for multi-screen development. For an in-depth session with code examples see the technical second part of this presentation in the Qt Application Development & Device Creation Track.
