Try using QDirModel and QTableView.

thanks
can i use QTreeWidget and QDirModel ?

[wysota]

No, you can't. What do you need QTreeWidget for? You can use QTreeView instead of the table view if you want.

[hbill]

i will use it in a ftp client, to view a local and server files ...
so i need a name, path and many informations of treewidget items to use with Qftp class

thanks

[wysota]

Use QTreeView with QDirModel as suggested.

[hbill]

If i use for exampl a mouse event, how can i identify which item on the treeview is clicked ?
for exampl on QTreeWidget i can use my class

class myTreeWidget:public QTreeWidget

class myTreeWidget:public QTreeWidget

To copy to clipboard, switch view to plain text mode 

void mousePressEvent (QMouseEvent *event)
signals:
   void itemClicked (QTreeWidgetItem *);
//......
void myTreeWidget::itemClicked(QMouseEvent * e)
{
   QTreeWidgetItem *selectedItem = itemAt(e->pos());
   emit itemClicked(selectedItem);
}

void mousePressEvent (QMouseEvent *event)
signals:
   void itemClicked (QTreeWidgetItem *);
//......
void myTreeWidget::itemClicked(QMouseEvent * e)
{
   QTreeWidgetItem *selectedItem = itemAt(e->pos());
   emit itemClicked(selectedItem);
}

To copy to clipboard, switch view to plain text mode 

how can i use like this on QTreeView
thank you

Dear all,

I am using QTableView with QDirModel to display the local file system.

I have set the filter with "QDir::AllEntries". it is displaying all folders and Files including "." and ".." items.

If I use QDir::NoDotAndDotDot, both "." and ".." is filtered.

I need only ".." but not "."

can anyone suggest me the way of doing this.

Thanks in advance.

[wysota]

Apply a sort filter proxy model that will filter out the single dot.

Dear all,

I have used QSortFilterProxyModel as per wysota's suggestion. its working fine. thanks for this.
can anyone help me with regular expression that should display only ".." not "."

proxyModel->setFilterRegExp ( QRegExp ( "......." ) );
proxyModel->setFilterKeyColumn ( 0 );

thanks in advance.

Am not sure but

"[^\.]"

ie. Anything except '.'
Also have a look at QRegExp

[ssaa]

thanks for your reply.

I have checked with this, but it filters both ".." and "."

my requirement is only ".."

You can subclass the proxy and reimplement its filterAcceptsRow() method.
