Editor's Notes
- #2: Wherever there is a screen, it can use or need an application. Qt Quick allows for scaleable UI that lets a simple code reuse function in various screen sizes, operating systems, hardwares etc. BC of Qt¡¯s full logic capabilities and extensive libraries all these applications, although in different form factors and OSs, can talk to each other and operate seamlessly. Qt future-prooves your application for platforms that might be the dominant ones in the future. With Qt you can create completely ?platform-independent? software that run everywhere in your end users¡¯ pockets
- #3: Qt for Device Creation and the industry vertical offerings; Qt in Automotive, Qt in Automation, Qt in Digital TV, Qt in Medical
- #4: It is common to look at open source as free of charge and without cost. Comparing this with the cost of a commercial license will certainly look tempting, but there are actual costs connected to open source as well. These costs are less predictable than the well defined costs connected to commercial licensing.
- #5: There are many hidden costs when embarking on the open-source adventure. It is important to have the full picture before starting the journey. With the Qt commercial license there are no hidden costs. The Qt Company will do the ¡°dirty job¡± for you below deck: Reduced development cost Less technical responsibility Access to consultancy services Improved performance Value adding features and tools Protection of your intellectual properties Professional support Reduced risk and increased security
- #10: Everything you need for your entire software development life cycle. Qt is the fastest and smartest way to produce industry-leading software that users love.
