Problems understanding layouts

leonardoMB

QGridLayout *layout = new QGridLayout();
  layout->setContentsMargins(6, 5, 6, 2);
  layout->addWidget(lastUpdatedMsg, 0, 1, 1, 1, Qt::AlignTop | Qt::AlignHCenter);
  layout->addWidget(_configWidget, 1, 0, 1, 1, Qt::AlignLeft);
  layout->addWidget(_graph, 1, 1);
  layout->addWidget(_Msg, 1, 1, 1, 1, Qt::AlignCenter);

So I printed the size of this layout and it says it 2x2. So What is going on here? Things are spaming over the others? there are more than 1 widget per cell space.

mpergand

layout->addWidget(_graph, 1, 1);
layout->addWidget(_Msg, 1, 1, 1, 1, Qt::AlignCenter);

these two are in the same cell
and nothing in cell 0,0
