C++ (Cpp) ModelItem::childCount Examples

Example #1

File: UIApplianceEditorWidget.cpp Project: virendramishra/VirtualBox4.1.18

void VirtualSystemModel::restoreDefaults(const QModelIndex &parentIdx /* = QModelIndex() */)
{
    ModelItem *parentItem;

    if (!parentIdx.isValid())
        parentItem = m_pRootItem;
    else
        parentItem = static_cast<ModelItem*>(parentIdx.internalPointer());

    for (int i = 0; i < parentItem->childCount(); ++i)
    {
        parentItem->child(i)->restoreDefaults();
        restoreDefaults(index(i, 0, parentIdx));
    }
    emit dataChanged(index(0, 0, parentIdx), index(parentItem->childCount()-1, 0, parentIdx));
}

Example #2

File: UIApplianceEditorWidget.cpp Project: virendramishra/VirtualBox4.1.18

int VirtualSystemModel::rowCount(const QModelIndex &parentIdx /* = QModelIndex() */) const
{
    ModelItem *parentItem;
    if (parentIdx.column() > 0)
        return 0;

    if (!parentIdx.isValid())
        parentItem = m_pRootItem;
    else
        parentItem = static_cast<ModelItem*>(parentIdx.internalPointer());

    return parentItem->childCount();
