How to change selection in QTableWidget on keypress



  • I'm looking for a documentation that would explain how the QTableWidget reacts on keystrokes.
    I have a 5x5 Table where I set the selection behaviour to QAbstractItemView::SelectRows. However, as soon I have one row selected, I can change the row by pressing keys on the keyboard. In my case for selection it is the first character in the cells of the second column, which is taking into account.
    How I can get the first or the third column getting crucial for the selection.
    Would someone please be so kind and point me to the place in doc, there I can find some notes how this implementation works and how to change it?

    Thank you in advance.
    Greg



  • @GregPhil
    Have you read QItemSelectionModel http://doc.qt.io/qt-5/qitemselectionmodel.html#details ?

    current selected items are part of the current interactive selection (for example with rubber-band selection or keyboard-shift selections).

    And http://doc.qt.io/qt-5/model-view-programming.html#handling-selections-in-item-views.

    I'm looking for a documentation that would explain how the QTableWindow reacts on keystrokes.

    BTW: QTableWindow is QTableView, or QTableWidget, or ...?



  • @JNBarchan
    oh yes I'm sorry, I mixed up the terms. It's always QTableWidget.
    I think your ansers apply to QTableView but not to QTableWidget?



  • @GregPhil
    QTableWidget inherits from QTableView so stuff still applies.

    I am a newcomer, but unless I am mistaken they do not offer any kind of inbuilt:

    can change the row by pressing keys on the keyboard. In my case for selection it is the first character in the cells of the second column

    , just mouse selection support. So that implies it is your code which has the logic for whatever it is doing for "selection by second column", and that is where you would put code to change this behaviour to whatever you desire?



  • @JNBarchan
    ok thank you very much.
    Strange, even if I got the same impression that only mouse selection support is provided by reading the documentation, keystrokes working as well. One can easy verify this. It's only the fact that I can't find any documentation how to adjust this behaviour it to my needs. However, the only idea I have for now (without having a look into it) seems to be an addaption by implementing/overwriting events.

    cheers
