Widget for the game "Life" on Qt?

Question

Qt

I decided to write an implementation of the game "Life" in C ++ using Qt. Which widget can be used as a field? If you draw manually, you will have to determine which cell was clicked by the cursor coordinates, this is inconvenient.

Answer 1

What's inconvenient?

void mousePressEvent( QMouseEvent* e ) {
    int row = e->pos().y() / CellSize;
    int column = e->pos().x() / CellSize;

    // do whatever you want

}

Answer 2

QGraphicsScene. And look at the examples of tic-tac-toe)

Answer 3

I made a turn of the model and the delegate, in the examples there is how to draw drawings in circles in the table, here the life modeler turns out to be beautiful)))
