[Qt-interest] parse items of QTreeWidget into file/QSettings

[André Somers]

Just like any other other QAbstractItemView derived class, QTreeWidget has a
method called “model()” that returns
 a QAbstractItemModel. I think it could
be the model you were after


 

Some tips on iterating over a tree model:

·         The root item(s) of your tree have an invalid parent QModelIndex,
that can be created using the default constructor of that class.

·         Using rows() you can find out the number of rows (as children of a
specified parent node) 

·         Each node in the tree may be the parent of other nodes, but in
your case, only the nodes in column 0 may be parents of other nodes!

·         You can use QAbstractItemModel::index() to create a valid index to
access the nodes of your model.

 

HTH,

 

André

No. I said that you can access the model QTreeWidget is using. Not to
implement your own...

Sorry to say that but you want to do some serious reading on C++, object-
oriented programming (look for classes and derivation) and then patterns
(mostly the Model-View(-Controller)-pattern) and Qt...
