I want to right click the particular treewidgetitem..

karti gesar

treeWidget = new QTreeWidget(this);
treeWidget->setContextMenuPolicy(Qt::ActionsContextMenu);
treeWidget->setHeaderLabel("Display");

Above code is what i used....for entire treewidget the right click appears...for me only for item right click should appear.....do you have any idea....

@karti-gesar

use setContextMenuPolicy(Qt::CustomContextMenu) and connect customContextMenuRequested(QPoint) to your slot and accept only if index is valid.

k i will try

karti gesar

treeWidget = new QTreeWidget(this);
treeWidget->setGeometry(0,0,200,200);
treeWidget->setContextMenuPolicy(Qt::CustomContextMenu);
connect(treeWidget, SIGNAL(customContextMenuRequested(const QPoint&)),
this, SLOT(ShowContextMenu(const QPoint&)));
}

void MainWindow::ShowContextMenu( const QPoint & pos )
{

QPoint globalPos = treeWidget->mapToGlobal(pos);
   // for QAbstractScrollArea and derived classes you would use:
   // QPoint globalPos = myWidget->viewport()->mapToGlobal(pos);

   QMenu myMenu;
   myMenu.addAction("Menu Item 1");
   // ...

   QAction* selectedItem = myMenu.exec(globalPos);
   if (selectedItem)
   {
       // something was chosen, do stuff
   }
   else
   {
       // nothing was chosen
   }

}

@karti-gesar
something like this

    QModelIndex index = ui->treeWidget->indexAt(point);
    if(index .isValid())
    {
     /// add actions here
    }

i don't know how to use this

Ratzz

@karti-gesar
This works for me
//cons

    ui->treeWidget->setContextMenuPolicy(Qt::CustomContextMenu);
    connect(ui->treeWidget,SIGNAL(customContextMenuRequested(QPoint)),this,SLOT(goHere(QPoint)));

//go here

    QMenu* menu = new QMenu("Menu",ui->treeWidget);
    QModelIndex index = ui->treeWidget->indexAt(point);
    if(index.isValid())
    {
        QAction *myaction  = new QAction(QIcon(":/new/prefix1/Icons/action.png"),"action",this);
        menu->addAction(myaction);
        menu->exec((QCursor::pos()));
    }

@karti-gesar said:

What do you mean?

Show me your code

karti gesar

for particular item only i want right....but for entire widget it appears

karti gesar

treeWidget = new QTreeWidget(this);

treeWidget->setContextMenuPolicy(Qt::ActionsContextMenu);
  treeWidget->setHeaderLabel("Display");


  //tree = new QTreeView(this);
       // tree->setModel(treeWidget);

  //Cpp file:

myAction = new QAction(tr("&Add Subprogram"), treeWidget);
connect(myAction, SIGNAL(triggered()), this, SLOT(mySlot()));
myAction1 = new QAction(tr("&Delete Subprogram"), treeWidget);
connect(myAction1, SIGNAL(triggered()), this, SLOT(deleteSubpgm()));
myAction2 = new QAction(tr("&AddProgram"), treeWidget);
connect(myAction2, SIGNAL(triggered()), this, SLOT(AddProgram()));
myAction3 = new QAction(tr("&DeleteProgram"), treeWidget);
connect(myAction3, SIGNAL(triggered()), this, SLOT(DeleteProgram()));
// Then add it to your treeWidget:
treeWidget->addAction(myAction);
treeWidget->addAction(myAction1);
treeWidget->addAction(myAction2);
treeWidget->addAction(myAction3);
prg1 = new QTreeWidgetItem(treeWidget);
prg1->setIcon(0,QIcon("C:/Users/skarthick.DART0/Downloads/clapperboard.png"));
prg1->setText(0, tr("Program1"));
}

void Dialog::mySlot()
{
qDebug()<<"ee";
osloItem = new QTreeWidgetItem(prg1);
static int i=1;
osloItem->setText(0, QString("Subprogram %1").arg(i));

i++;
if(i>=12)
{
    QMessageBox msgBox;
    msgBox.setText("no more to add.");
    msgBox.exec();
}

}

void Dialog::deleteSubpgm()
{
osloItem = treeWidget->currentItem();
if(osloItem)
delete osloItem->parent()->takeChild(osloItem->parent()->indexOfChild(osloItem));

}
void Dialog::AddProgram()
{
prg2 = new QTreeWidgetItem(treeWidget);
static int j=2;
prg2->setIcon(0,QIcon("C:/Users/skarthick.DART0/Downloads/clapperboard.png"));
prg2->setText(0, QString("program %2").arg(j));
j++;

}
void Dialog::DeleteProgram()
{
prg2= treeWidget->currentItem();
if(prg2)
{

delete prg2->parent();

}
}

@karti-gesar
I don't see any checking for valid index . i.e index.isValid() ??

Hi,

Like @Ratzz wrote, you should use Qt::CustomContextMenu not Qt::ActionsContextMenu.

The use of CustomContextMenu will trigger the customContextMenuRequested signal and you'll build your contextual menu in the slot connected to it.

i will try it,,,
