[Qt-interest] QStandardItemModel spread only with one click

[David Boosalis]

If your using a QTreeView (I think it will work for QTreeWidget.

You can capture the mouse event yourself test it and then emit a signal to
expand all.  Something like this:

void MyTreeView::mousePressEvent(QMouseEvent *me)
{
  QModelIndex index;
  if (me->button() == Qt::RightButton) {  // or use left mouse button if you
lie
    index = indexAt(me->pos());
    if (index.isValid()) {
      me->accept();
      emit itemClicked(index,me->globalPos());
   }
  else
    QTreeView::mousePressEvent(me);
}


MyParentWidget::itemPressedSlot(ModelIndex mi, QPoint pos)
{
  QStandardItem *item = myModel->itemFromIndex(mi);


}
