Is there any thorough tutorial for developing mobile applications with Qt 5.3?
I didn't find any good tutorial or well described step by step example. Almost all QML and Qt Quick tutorials and examples are old.

It would be great if someone here could help me and answer just some of numerous questions.


1. How to start? The app is supposed to run on Android and iOS devices. Create new Qt Quick Application project or something else?
2. How to create custom buttons with background color/image and text? Should it be customized Button control or Rectangle with child objects Image and text?
3. How to create and handle button_click event? Where is it handled, in C++ code behind QML file?
4. How are QML and C++ classes/files connected?
5. How to create couple of pages and navigate through them, i.e. after button click on one page, the other page should be opened?
6. Where are saved user data from application? For example, Settings page have some textboxes and value that user entered must be saved ond available after opening the app next time?


There are a lot of questions but there is no point to write them all.
