Which Common Model can be used for Tree View Display and List View Display ?

[Talei]

Does b/d are another column in Your model? If so it seams that You listView display only colum 0, with is default, simply use:

listView->setModelColumn( 1 );

listView->setModelColumn( 1 );

To copy to clipboard, switch view to plain text mode 

or any other column number, that you want to display. ListView displays only one column in view.

No they are not another column, they are rows which are children of A and C.

The display Got Formatted in last post, Actual Tree View is :
A
(Tab)b
C
(Tab)d

This is how I am creating the Model:

QStandardItemModel *Treemodel = new QStandardItemModel(0,1);

QStandardItem* item1 = new QStandardItem("A");
QStandardItem* item2 = new QStandardItem("C");

QStandardItem* item3 = new QStandardItem("b");
QStandardItem* item4 = new QStandardItem("d");

item1->appendRow(item3);
item2->appendRow(item4);

So, a TreeVIew for this Model displays all items but A ListView only displays A and C. I want all of them to be displayed on which I can apply some filter to show only Children
Thanks

AFAIK in your current implementation You can't do that, because ListView is one-dimensional list (that's why You can see item1/2, they are parents for children items), so there is, AFAIK "no way" to display 2d matrix. Workaround would be to create 1D list, but You will loose all hierarchy information that way.
Also if You want to show only children in ListView, you can traverse through all parents items (item1/2), build model and display only that in ListView.

Your treemodel will index every element added to the tree.

For any given item in the tree you can get the other elements at the same level using the sibling function.

For more info take a look at the documentation for QModelIndex.

Store your data in a basic table model with a the hierarchy you want for your tree view. If the children you want to show in your list view are all of the same parent then you might consider using a single-columned tree view and QTreeView::setRootIndex(). If not, as would seem to be the case in your example, write a QAbstractItemProxyModel derivative to filter the underlying table to produce a single-columned list for your list view.

I think the browser example in the Qt distribution/demos contains an implmentation described here http://labs.trolltech.com/blogs/2008...-of-modelview/

Thanks a lot guys.... Tried a bit but the solution seems to be somewhat complex ..Going with a Two Model Strategy right now and will try on the suggestion again
sometime later .
