#include "mytreeview.h"
 
MyTreeView::MyTreeView(QWidget *parent) :
    QTreeView(parent)
{
    this->setContextMenuPolicy(Qt::CustomContextMenu);
    connect(this,SIGNAL(customContextMenuRequested(QPoint &point)), this, SLOT(slotCustomContextMenu(QPoint &point)));
}
 
void MyTreeView::slotCustomContextMenu(QPoint &point)
{
     QMenu *menu = new QMenu;
     QModelIndex index = this->currentIndex();
 
     QString fileName = this->model()->data(this->model()->index(index.row(), 0),0).toString();
     menu->addAction(QString("Import"), this, SLOT(slotTest()));
     menu->addAction(QString("Export"), this, SLOT(slotTest()));
     menu->exec(QCursor::pos());
}
 
void MyTreeView::slotTest()
{
}

#include "mytreeview.h"

MyTreeView::MyTreeView(QWidget *parent) :
    QTreeView(parent)
{
    this->setContextMenuPolicy(Qt::CustomContextMenu);
    connect(this,SIGNAL(customContextMenuRequested(QPoint &point)), this, SLOT(slotCustomContextMenu(QPoint &point)));
}

void MyTreeView::slotCustomContextMenu(QPoint &point)
{
     QMenu *menu = new QMenu;
     QModelIndex index = this->currentIndex();

     QString fileName = this->model()->data(this->model()->index(index.row(), 0),0).toString();
     menu->addAction(QString("Import"), this, SLOT(slotTest()));
     menu->addAction(QString("Export"), this, SLOT(slotTest()));
     menu->exec(QCursor::pos());
}

{
}

treeview work but right click dont show menu ;( some advice ??

As far as I remember it is not necessary to create context menu for the treeview manually. Try something like this:

treeView->setContextMenuPolicy(Qt::ActionsContextMenu);
treeView->addAction(yourAction1);
treeView->addAction(yourAction2);
...

treeView->setContextMenuPolicy(Qt::ActionsContextMenu);
treeView->addAction(yourAction1);
treeView->addAction(yourAction2);
...

Keep in mind slotCustomContextMenu is not really necessary unless you want to implement some custom menu behavior. Take a look at the project attached.

Handle selectionChanged or click events and disable/enable your actions there.
