QDirModel and QTreeView

hi guys,

i have a littel problem with QDirModel.

Code:

---

QString workspace = QFileDialog::getExistingDirectory( this, tr("Open worspace"), QDir::homePath() );
if ( workspace.isEmpty() )
    return;
 
QDirModel *model = new QDirModel();
model->setFilter( QDir::AllDirs );	
model->setLazyChildCount( true );
model->setData( model->index( workspace ), QVariant(workspace), Qt::DisplayRole );
model->setHeaderData(0, Qt::Horizontal, workspace); 
 
tvWorkspace->setModel( model );
tvWorkspace->setRootIndex( model->index( workspace ) );
tvWorkspace->header()->setSortIndicatorShown( true );
tvWorkspace->header()->setClickable( true );
tvWorkspace->setColumnHidden( 1, true );
tvWorkspace->setColumnHidden( 2, true );
tvWorkspace->setColumnHidden( 3, true );
 
connect( tvWorkspace, SIGNAL( clicked( const QModelIndex & ) ), this, SLOT( workspaceItemChanged( const QModelIndex & ) ) );

---

it is work but i see only the folders in this QTreeView:

|-include
|-src
|-ui

but i would like this:

/home/alex/project/test
|-include
|-src
|-ui

i searched on forum index, but can not found items of this ....
but how? can anyone help me? .....

You mean you want the whole directory path to be displayed for the root item?

yes,

but i can not find examples/solution for this :(
i have all tested ..... or? :confused:

Subclass the model and reimplement data() to return an absolute path for items with invalid parents, more or less like so:

Code:

---

QVariant MyDirModel::data(const QModelIndex & index, int role) const{
  if((role==DisplayRole || role==EditRole) 
  && index.isValid() && !index.parent().isValid()) 
    return filePath(index);
  return QDirModel::data(index, role);
}

---

the target is nearby :D

Code:

---

MTWorkSpaceModel *model = new MTWorkSpaceModel();
 
QDirModel *modelDir = new QDirModel();	
modelDir->setFilter( QDir::AllDirs );
modelDir->setLazyChildCount( true );
QVariant data = model->data( modelDir->index( workspace ), Qt::DisplayRole );
qDebug() << data; // data returns QVariant(QString, "/home/alex/test")
 
modelDir->setData( modelDir->index( workspace ), data, Qt::DisplayRole );
 
dirModel = modelDir;
 
tvWorkspace->setModel( modelDir );
tvWorkspace->setRootIndex( modelDir->index( workspace ) );
tvWorkspace->header()->setSortIndicatorShown( true );
tvWorkspace->header()->setClickable( true );
tvWorkspace->setColumnHidden( 1, true );
tvWorkspace->setColumnHidden( 2, true );
tvWorkspace->setColumnHidden( 3, true );
 
connect( tvWorkspace, SIGNAL( clicked( const QModelIndex & ) ), this, SLOT( workspaceItemChanged( const QModelIndex & ) ) );

---

MTWorkSpaceModel

Code:

---

QVariant MTWorkSpaceModel::data( const QModelIndex & index, int role ) const {
	if((role == Qt::DisplayRole || role == Qt::EditRole ) && index.isValid() && index.parent().isValid())
	    return filePath( index );
 
	return QDirModel::data( index, role );
}

---

but not realy function .... why? is the error on

Code:

---

modelDir->setData( modelDir->index( workspace ), data, Qt::DisplayRole );

---

or

Code:

---

tvWorkspace->setRootIndex( modelDir->index( workspace ) );

---

sorry for my bad english

What exactly doesn't work? Could you describe the problem?

i have the subclass created and QDirModel reimplemented with QVariant data(...)

in the code (see above) set i the data of QDirModel with my subclass ....
but it is not function, i see in the treeview only the folder
|-ui
|-src
|-include

but not
/home/alex/test
|-ui
|-src
|-include

in short form: i can not see rootItem .....

See the attached file for a working version.

thank you very much, for this example, i'm so happy and it works *kiss* :D
