This is useful if your application always needs a certain set of files (icons, translation files, etc.) and you dont want to run the risk of losing the files.The resource system is based on tight cooperation between qmake, rcc (Qts resource compiler), and QFile. Qt framework provides localstorage QML type using which you can store data in SQLite database. And to store images, can make use of resources system of QT but cannot write any files in resources system because resources files are converted to bainry form when QT application got compiled. So to store images better to go with resources system and to manipulate data go with SQLite localstorage. Qt is written in C++. In C++, you can create heap objects or stack objects. A heap object is created using new()† and returns a pointer-to-object. A stack object is just created automatically on the stack when you declare it directly.
Stack objects are occasionally useful, but the key thing about them is that they have very limited and strictly defined lifetimes. They are destroyed immediately they go out of scope. As such, in most cases they are not what you want, and in fact most other OOP languages don’t support the same concept.Qt is cross platform and mostly useful for desktop applications & embedded ones . Many corporations use Qt in house to develop desktop applications. Applications have also been coded for the mobile platform using the Qt framework. A handful of apps have been developed in Qt on Android. Android apps can be developed with QT so no Java required. For use of C++, take note that that Qt boasted some rather advanced design, such as signals and smart pointers. One key feature is the signal and slot mechanism, a great way to get different pieces of your program to send messages to each other. Supported platforms are Mac, Windows, Linux, Blackbery, Android, and iOS.
