I am trying to use simple tree model, but I am not able to make the example works in my project.
First, I was able to use QTreeView without problem, with QStandardItemModel. In the following case, I am able to see my QTreeView with data inside. See the working code :
constructor{
m_pModel = new QStandardItemModel();
ui.treeViewDevicesList->setModel(m_pModel);
fillTreeView(devicesList);
}
void GatewayDeviceViewerEditor::fillTreeView(const std::vector<Payload> &devicesList)
{
QVector<QStandardItem *> parents(MAX_PARENTS);
parents[0] = m_pModel->invisibleRootItem();
for (vector<Payload>::const_iterator it = devicesList.begin() ; it != devicesList.end(); ++it)
{
QStandardItem *pTreeViewItem = new QStandardItem();
string rootTitle = it->deviceId + " " + it->deviceName + " " + it->status ;
pTreeViewItem->setText(rootTitle.c_str());
parents[0]->appendRow(pTreeViewItem);
// parents[1] = pTreeViewItem;
}
}
Now, the following code is NOT working. I am trying to subclass the model. In that case, the QTreeView is showing up but completly empty. There is something that I guess that I don't understand.
entryPoint{
DeviceTreeModel deviceTreeModel(devicesList);
ui.treeViewDevicesList->setModel(&deviceTreeModel);
}
DeviceTreeModel::DeviceTreeModel(const std::vector<Payload> &devicesList, QObject *parent)
: QAbstractItemModel(parent)
{
QList<QVariant> rootData;
rootData << "Title" << "Summary";
m_pRootItem = new DeviceTreeItem(rootData);
setupModelData(devicesList, m_pRootItem);
}
void DeviceTreeModel::setupModelData(const std::vector<Payload> &devicesList, DeviceTreeItem *parent)
{
QList<DeviceTreeItem*> parents;
parents << parent;
for (vector<Payload>::const_iterator it = devicesList.begin() ; it != devicesList.end(); ++it)
{
string rootTitle = it->deviceId + " " + it->deviceName + " " + it->status ;
QString test(rootTitle.c_str());
QList<QVariant> columnData;
columnData << test << "Summary";
parents.last()->appendChild(new DeviceTreeItem(columnData, parents.last()));
}
}
