[Qt-interest] QGridLayout addWidget

[Leonardo M. Ramé]

Hi, I'm trying to replace the widget of a "cell" in a QGridLayout, 
but if I use the code below, I get a SigSegv:

myLayout->addWidget(m_widgets.value(0), row, col);

m_widgets is a QHash<int, QMyWidget>, where I have inserted one item
using insert(0, new QMyWidget()).

The layout is a 3x3 grid, so I want to replace the cell (row, col) with
a different widget.

How can I do this?.
