    Default Master - Detail in QML ListViews. A ListView with a delegate with another ListView.

    I have a ListView (A) that on it's delegate has another ListView (B). How can (B) objects change when the user changes from one item to another in (A)?

    For exemple:

    Imagine that I have a list of persons, and every person has a list of cars:
    - Person1 - car1, car2, car3
    - Person2 - car4
    - Person3 - car5, car6, car7, car8
    - Person4 - car9, car10
    ...

    The QML has a ListView (A) that it's delegate has another ListView (B). The parent ListView (A) shows the Person data, and the detail ListView (B) must show the cars of that person.

    Qt Code:
    1. // A ListView
    2. ListView {
    3. model: personModels
    4. delegate: Row {
    5. Text {
    6. text: model.name
    7. }
    8. Text {
    9. text: model.street
    10. }
    11. ...
    12. // B ListView
    13. ListView {
    14. model: ????
    15. delegate: Row {
    16. Text {
    17. text: model.carColor
    18. }
    19. }
    20. }
    21. }
    22. }
    To copy to clipboard, switch view to plain text mode 

    The problem is that the second ListView must change the model for every item in ListView A.

    How can I do it?

    You need a property in "personModels" that contains the cars for that person.
    Then you can just write something like
    Qt Code:
    1. model: model.cars
    To copy to clipboard, switch view to plain text mode 

    What's the type behind "personsModels"?

    Cheers,

    Yes, it work's, but in the QML can't put model., it gives error.

    It must be:

    Qt Code:
    1. model: cars
    To copy to clipboard, switch view to plain text mode 

    Cheers
