QDirModel (filter files, custom Icon, look)

[prashant]

Hi,

This is my first post.....

QDirModel *model = new QDirModel(this);
model->setReadOnly(true);
 
model->setSorting(QDir::DirsFirst | QDir::IgnoreCase | QDir::Name);
model->setFilter(QDir::Dirs | QDir::Files | QDir::NoDotAndDotDot);
 
 
QTreeView *treeView = new QTreeView;
treeView->setModel(model);
QDir dir("../node");
treeView->setRootIndex(model->index(dir.path()));

QDirModel *model = new QDirModel(this);
model->setReadOnly(true);
   
model->setSorting(QDir::DirsFirst | QDir::IgnoreCase | QDir::Name);
model->setFilter(QDir::Dirs | QDir::Files | QDir::NoDotAndDotDot);


QTreeView *treeView = new QTreeView;
treeView->setModel(model);
QDir dir("../node");
treeView->setRootIndex(model->index(dir.path()));

To copy to clipboard, switch view to plain text mode 

The above code is working fine. I need to do three more things. The further directory structure inside ("node") directory consists more directories with (.xml,.bmp,.txt) files.

How do I edit QDirModel so that:

1. It should only shows directories and ".xml" files only.

2. Every ".xml" file has equivalent ".bmp" file in the same directory. For e.g. "tree.xml" & "tree.bmp". By default ".xml" files shows system's icon. I need to show the ".bmp" icon
instead of default icon.

3. I don't need the header with colums (Name, Size, Type etc.)

Regards

Prashant

Subclass QSortFilterProxyModel, filter out the entries you don't need and reimplement the data() method to return proper icons. Then position your proxy model between the source model and the view.
