    Smile Can't I modify qlistview's item? can i modify only qlistwidget's item?

    I want to modify listview's item.

    so I add code this:

    Qt Code:
    1. setEditTriggers(QAbstractItemView::DoubleClicked | QAbstractItemView::SelectedClicked);
    To copy to clipboard, switch view to plain text mode 

    but anythings are not changed.
    I double-click listview's item, but i can't edit item..

    I show some example about editing tablewidget's item.

    Can I edit only listWIDGET or tableWIDGET, NOT listVIEW, tableVIEW??

    than why listview has <setEditTriggers>function??
    I can't understand.....

    PLEASE HELP ME!

    have you examined the model -view examples?
    If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

    Thanks for your answer!

    sorry..
    Where is model-view example?
    I examined only itemview example.
    I can't find model-view example.
    Is right you mean example of qt\4.8.2\exmaples?

    I think editable itemview's exmaple is only listwidget not listview..
    Isn't it??

    The model underlying the view class needs to be editable or the view will not be able to edit it regardless of the edit triggers. The model needs to return Qt::ItemIsEditable amongst the flags() for the items the model allows editing for.

    I FIND EDITABLE LISTVIEW EXMAPLE!
    but, this example use QStringListModel.
    so I change QStingListModel to QAbstractListModel that i reimplement.
    than this exmaple is broken! changed to no-editable ...
    why????

    thankyou ChrisW67.
    actually I can't fully understand you're answer.
    but roughly understanding, i add code
    Qt Code:
    1. Qt::ItemFlags GalleryModel::flags(const QModelIndex & index)
    2. {
    3. return Qt::ItemIsEditable;
    4. }
    To copy to clipboard, switch view to plain text mode 

    GalleryModel is my QAbstractListModel...

    isn't what you mean?
    but still item's not changed..

    when called flag function of model?
    I can't understand

    oh my god....
    You were right!
    I reimplement flags and setdata function. but It is not activate properly. so I ask a question you continues..
    Because I think i do all action for listview's editable, I am very confused.
    But I find I droped word 'const' in my flags function
    And I got the all I wants.
    THANK YOU! THANK YOU!

    sprit Thanks for your interest.
    Actually, i can't understand 'This should spill the light.'s mean..
    It means you need more information?
    I can't speak english, well. sorry.
    IF we will meet next time, help me please! thank you
