display informations of QDirModel on QDialog

[hbill]

hi
i have a QTreeView with QDirModel,
on right click on a QTreeView lines, i display a menu context :

//slot
void MyTreeView::showContextMenu(QModelIndex index, QPoint point)
{
    QString fP = ( (QDirModel *)model() )->fileInfo( index ).absoluteFilePath ();
    myAction *propertyAction = new myAction(QIcon("../img/property.png"), tr("&Proprietes"), this, tr("Ctrl+P"));
    connect( propertyAction, SIGNAL( triggered() ), this->parent(), SLOT( showDialogInfo() ) );
    QMenu treeMenu;
    treeMenu.addAction(propertyAction);
    treeMenu.exec(point);
}

//slot
void MyTreeView::showContextMenu(QModelIndex index, QPoint point)
{
    QString fP = ( (QDirModel *)model() )->fileInfo( index ).absoluteFilePath ();
    myAction *propertyAction = new myAction(QIcon("../img/property.png"), tr("&Proprietes"), this, tr("Ctrl+P"));
    connect( propertyAction, SIGNAL( triggered() ), this->parent(), SLOT( showDialogInfo() ) );
    QMenu treeMenu;
    treeMenu.addAction(propertyAction);
    treeMenu.exec(point);
}

To copy to clipboard, switch view to plain text mode 

and i have a QDialog, i want display on this QDialog all information of directory or file selected (name, path, permission, owner, size .....) with the slot showDialogInfo();

connect( propertyAction, SIGNAL( triggered() ), this->parent(), SLOT( showDialogInfo(fP) ) );

connect( propertyAction, SIGNAL( triggered() ), this->parent(), SLOT( showDialogInfo(fP) ) );

class myMainWindow : public QMainWindow
{
    Q_OBJECT
public:
    myMainWindow( QWidget * parent = 0, Qt::WindowFlags flags = 0);
    ~myMainWindow();
private:
    MyTreeView *localDir;
    QComboBox *homeDir;
    myDialog *dialog;
private slots:
    void showDialogInfo();
};
 
void myMainWindow::showDialogInfo()
{
    dialog->show();
}

Hi, what's about

if (treeMenu.exec(point) == propertyAction)
  this->parent()->showDialogInfo(fP);

if (treeMenu.exec(point) == propertyAction)
  this->parent()->showDialogInfo(fP);

To copy to clipboard, switch view to plain text mode 

in MyTreeView::showContextMenu.
or even better

if (treeMenu.exec(point) == propertyAction)
  emit mySignalShowDialogInfo(fP);

if (treeMenu.exec(point) == propertyAction)
  emit mySignalShowDialogInfo(fP);
