TreeModel, remove an item pointed by an index

[Patou355]

Hi all.

I use the stuff described here that basically is a subclass of QAbstractItemModel

My question is very simple but I feel I tried everything.

How can I erase an item of a TreeModel if I have an index pointing to it?

    QModelIndex cycleModelIndex;
    QModelIndex cycleModelIndexChild;
    cycleModelIndex = model->index(2,0);

and I want to kill the item pointed by cycleModelIndex...

Hi,

Isn't that what

TreeNode * TreeModel ::nodeForIndex(const QModelIndex &index) const;
void TreeModel ::removeNode(TreeNode *node);

are for ?

@SGaist Not really. They are only if your tree has only 1 column (i.e. that method removes the entire row). since the linked model only supports 1 role, however, you can just set the Qt::DisplayRole data of the index to QVariant() (you'll probably have to reimplement setData in the model to achieve this)
