What is the difference between Qt for Symbian and Qt for MeeGo? I know Qt is a cross-compiling platform. Does this mean that if I use a library from Qt the exact same library works on all devices which support Qt (e.g. Symbian, MeeGo)?
For example:
QtDesktopServices can launch a web browser. Despite the name ‘Desktop’ is confusing for mobile devices can I launch a web browser on every device which supports Qt? If I look at MeeGo, MeeGo is used for different kind of devices e.g. In-Vehicle, TV, media phone
Is it guaranteed that every device has a web browser on it? I don’t think so and that’s why I’m asking. If a browser is guaranteed, which browser is it? Which features does it have? I know there is WRT, but a user here stated that WRT has discontinued. So what now?
Do I have to choose between Qt 4.7 and Qt Mobility 1.0?
What leinir said – Qt Mobility is a module that implements common features for mobile devices. Qt’s API is the same on all platforms, though there are some platform-specific functions (mainly dealing with low-level stuff).
While the API (the interface) is the same, the implementation of course may be different. I suggest looking at the Qt online documentation – the pages linked under “Platform-specific Development”
According to “Platform notes – Symbian”, the Symbian port is not complete and lacks some features (e.g. OpenGL support is “planned for a future release”, while printing probably never will be supported). I’m pretty sure that the MeeGo/Maemo version supports OpenGL ES, as I’ve seen a Qt-based application using it (Stellarium on a Nokia N900).
