    Default How to get data from TableView - QML Desktop Components

    Anyone has an idea how to get data from currently selected item from TableView?
    In ListView there is currentItem, but in TableView there is only currentIndex. Index should be enough, just get data at index. But how do do that? It should be extremely simple.

    I'd like to get item and show additional info (description) in separate text area.

    Any ideas?

    Hmmm... by getting the index number from currentIndex.row ?

    currentIndex itself is row index so I have row index but still no idea how to get object at this index. I can get it from python backend, but I don't want to - unnecessary redundant code.
    If I have ListView there is currentItem and I'm able to operate directly on this item.

    Doesn't this work?

    javascript Code:
    1. model.get(currentIndex).someRole
    To copy to clipboard, switch view to plain text mode

    TypeError: Result of expression 'model.get' [undefined] is not a function.

    The same with model[currentIndex]

    TypeError: Result of expression 'model[currentIndex]' [undefined] is not an object.

    Is model a "ListModel" or some other kind of model?

    In python implementation of AbstractListModel.
    Of course all data from model appears correctly.

    If it's a QAbstractItemModel then you need to provide your own method for accessing data from the model.

    I suggest an equivalent of the following:
    Qt Code:
    1. QVariantMap Model::get(int idx) const {
    2. QVariantMap map;
    3. foreach(int k, roleNames().keys()) {
    4. map[roleNames().value(k)] = data(index(idx, 0), k);
    5. }
    6. return map;
    7. }
    To copy to clipboard, switch view to plain text mode
