QDirModel and QTreeView

[ChMaster]

hi guys,

i have a littel problem with QDirModel.

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 & ) ) );

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 & ) ) );
