[Qt-qml] Views and models

[Cornelius Hald]

Hi,

I´m new to QML and Qt, so please excuse my beginner questions. To get 
acquainted with QML I´m trying to do a small multi-media slide show 
thing. Basically it should show pictures with some text and play some 
audio file. A simple XML model could look like this:

<slideshow>
   <slide id="1">
     <image>http://example.com/img1.jpg";</image>
     <audio>http://example.com/snd1.mp3";</audio>
     <text>Some text...</text>
   </slide>

  [...]

   <slide id="42">
     <image>http://example.com/img42.jpg";</image>
     <audio>http://example.com/snd42.mp3";</audio>
     <text>Some other text...</text>
   </slide>

</slideshow>

My view should have a 'previous' and a 'next' button and always show one 
picture + text + audio. Once someone clicks the 'next' button the next 
slide should be shown.

Building the view was no problem and it´s working as expected, the 
problem is how to build the model for the view and how to present it to 
the view. (The view is just a .qml file, so not a view like the e.g. the 
ListView.)

I´ve looked at ListModel and XmlListModel and I think they provide all I 
need on the model side. Then for the view part I looked at ListView, 
GridView and PathView, but somehow those views are made to show all 
items at once and I only want to display one item a time.

Do I have to create my own *View class? If yes, do I have to do this 
with C++ or is there a way to build a custom view using only QML/JS? I 
was trying to pass a ListModel into my view just by binding properties, 
but that doesn´t seem to work.

It could be that I´m missing something obvious here, if so, please tell 
me :)

All pointers would be very much appreciated and if something is unclear 
I´ll provide more information.

Thanks!
Conny
