Dynamically select TreeView item.

[dayobject]

I have a signal/slot hooked up to return an object that exists within my treeview model.

My question is, how can I find the particular item in the tree view based on this model data? Do I need to traverse the entire tree structure to find a match?

Does something like below exist?

QModelIndex indexOfTreeItem = m_pCurrentModel->findIndex(modelData);

Thanks.

Hi and welcome to devnet,

Are you using a custom model ? If so, it's up to you to provide the findIndex method for your model.

probably the best would be to store the object in a hash-table for quick lookup.
But make sure to cleanup the hash table once the object is destroyed to avoid dumping the memory.

@SGaist Thanks. I'm not using a custom model, though it's looking like I might need to write a custom method to find the value.

about how many tree items are we talking here?
Is the model static or dynamic (items added/removed during runtime)?
