Obtain index of child's parent

[webquinty]

Hello,

I can obtain index of child and text of parent, but I am interesting to obtain index of both.

QTreeWidgetItem *parent = myItem->parent();
QString nameItem;
int index;
 
      index = parent->indexOfChild(ui->deviceTree->currentItem());            
      nameItem = parent->text(indice);

QTreeWidgetItem *parent = myItem->parent();
QString nameItem;
int index;

      index = parent->indexOfChild(ui->deviceTree->currentItem());            
      nameItem = parent->text(indice);

To copy to clipboard, switch view to plain text mode 

any advice???
Best regards

well, to get the index of the parent, you must ask the grandparent, i.e. the parent of the parent, (or the QTreeWidget, if no grandparent exists)

Any example to understand it???

QTreeWidgetItem *child = /*currentItem() or whatever*/;
QTreeWidgetItem *parent = child->parent(); //check if valid
QTreeWidgetItem *grandparent = parent->parent(); //check if valid
int index_child = parent->indexOfChild(child);
int index_parent = grandparent->indexOfChild(parent);

QTreeWidgetItem *child = /*currentItem() or whatever*/;
QTreeWidgetItem *parent = child->parent(); //check if valid
QTreeWidgetItem *grandparent = parent->parent(); //check if valid
int index_child = parent->indexOfChild(child);
int index_parent = grandparent->indexOfChild(parent);

Thank you very much, I did not understand what was grandparent.
