A way to know the current element edited on QGridLayout?



  • Hello, a simply question. When we have a QLienEdir matrix, like the image below shows,

    Exist a way to know the position in grid, of the current element edited? Or we have to connect 100 signals and 100 slots in a 100x100 matrix

    my idea is connect all to one slot and decide there, which signal corresponds in a particular string matrix

    like always, any ideas or suggestions are welcome

    thanks in advance.
    Greetings

    Hi
    You can use
    http://doc.qt.io/qt-5/qsignalmapper.html#details

    Also, you can connect many signals to same slot.
    in the slot u can use the sender() function
    to know which widget was the signal sender.

    While you can ask Which widget has focus, the correct way is
    to use signals.
