Split pane view with different headers.

I figured out my problem. In my QSortFilterProxyModel, I had to reimplement all the public methods from my model.

One other question, do I need to reimplement the mapToSource and mapFromSource in my QSortFilterProxyModel or will the base methods work?

I ask because I have not reimplemented them and when I set a certain location to expand in the tree view, it is expanding the wrong location in the view, so it's like it's getting the wrong indices for the items.

Okay, any help from anyone will be much appreciated. I've worked through any of the above problems that I had.

I have a model, a tree proxy model and a table proxy model and two views a tree view and a table view. The Proxy's are based on QSortFilterProxy. The treeview gets the data and displays it (filtered to be only folders). The table view is supposed to only display the data matching it's set parent, for example a users home directory. The treeview/proxy model works fine.

The problem is that the table view/proxy does not recieve data from the model. If I connect a signal/SLOT on rowsInserted, then I can see that the filter sees the top level data, but does not display anything. In addition, the table proxy model's data method is never called.

Here are some snippets.
class MyDataModel : QAbstractItemModel
class MyTreeProxyModel : QSortFilterProxyModel
class MyTableProxyModel : QSortFilterProxyModel

QTreeView *myTreeView;
QTableView *myTableView;

In Mainwindow::Mainwindow()

MyDataModel *dataModel = new MyDataModel();
// Sets the root directory to display
dataModel->setRoot("/");
MyTreeProxyModel *treeProxy = new MyTreeProxyModel();
MyTableProxyModel *tableProxy = new MyTableProxyModel();

treeProxy->setSourceModel(dataModel);
tableProxy->setSourceModel(dataModel);

// Sets the directory on which to filter..
tableProxy->setParent("/home/user1");

myTreeView = new QTreeView();
myTreeView->setModel(treeProxy);

myTableView = new QTableView();
myTableView->setModel(tableProxy);

QSplitter* splitter = new QSplitter(this);
splitter->addWidget(myTreeView);
splitter->addWidget(myTableView);
setCentralWidget(splitter);

//This starts the process, i.e. the tree view recieves and displays data
setRootPath("/home/user1");
---------------------------------------

What I need to do is display a list of folders on one side in a tree and in the other side in tabular form, information about the children of a selected folder. You can think of windows explorer in how it's supposed to behave.

Example data:
FOLDERS----------------------------------------- NAME INFO1 INFO2 INFO3

/folder1------------------------------------------- file1 info1 info2 info3
/folder2------------------------------------------- file2 info1 info2 info3
+/home/user1
/file1
/file2
/folder3
.
.
.

I appreciate any help in advance.

Has anyone seen this or have any ideas? I really need to get this working.

Did you remember to emit appropriate signals from the proxy when "things happen" in the base model?

[chocolate]

Yes, I do emit the signal and see that it is emited and received.

I can also see the data going through the filter, but the tableProxy's data method is never called. The treeproxy's data method is called (although it's just a pass through to the underlying model).
