[solved]How to get options on right click of mouse in a tableview

Ratzz

I have a tableview set to a QStandardItemModel . I have 6 rows and 4 column in it . each cell has "item 0" by default. When an user select some cell on the mouse i want some options to be displayed on the right click of the mouse.
mymodel.cpp

mymodel::mymodel(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::mymodel)
{
    ui->setupUi(this);
    moniterFilterModel = new QStandardItemModel(6,4,this);
    ui->tableView->setModel(moniterFilterModel);
    for(int row = 0; row < 6; row++)
    {
        for(int col = 0; col < 4; col++)
        {
            QModelIndex index= moniterFilterModel->index(row,col,QModelIndex());
            moniterFilterModel->setData(index,"Item 0") ;
        }
    }
    connect(ui->tableView,SIGNAL(customContextMenuRequested(QPoint)),this,SLOT(MonitorFilterContextMenu(QPoint)));
        ui->tableView->setMouseTracking(true);
        ui->tableView->viewport()->setAttribute(Qt::WA_Hover,true);

void mymodel::MonitorFilterContextMenu(QPoint position)
{
    Q_UNUSED(position);
    QAction *pTxAction  = new QAction("Change to Tx",this);
    connect(pTxAction,SIGNAL(triggered()),this,SLOT(ChangeSelectedToTx()));

    QAction *pRxAction  = new QAction("Change to Rx",this);
    connect(pRxAction,SIGNAL(triggered()),this,SLOT(ChangeSelectedToRx()));

    QAction *pTRAction  = new QAction("Change to TR",this);
    connect(pTRAction,SIGNAL(triggered()),this,SLOT(ChangeSelectedToTR()));

    QAction *pDisableAction  = new QAction("Disable Monitoring",this);
    connect(pDisableAction,SIGNAL(triggered()),this,SLOT(DisableMonitoringForSelectedItems()));

    QMenu *pContextMenu = new QMenu( this);
    pContextMenu->addAction(pTRAction);
    pContextMenu->addAction(pTxAction);
    pContextMenu->addAction(pRxAction);
    pContextMenu->addAction(pDisableAction);
    pContextMenu->exec(QCursor::pos());
}

void mymodel::ChangeSelectedToTR()
{
    QModelIndexList selectedItemList = ui->tableView->selectionModel()->selectedIndexes();
    foreach(QModelIndex itemIndex, selectedItemList)
    {
        moniterFilterModel->setData(itemIndex, QVariant("TR"));
    }
}

void mymodel::ChangeSelectedToTx()
{
    QModelIndexList selectedItemList = ui->tableView->selectionModel()->selectedIndexes();
    foreach(QModelIndex itemIndex, selectedItemList)
    {
        moniterFilterModel->setData(itemIndex, QVariant("T"));
    }
}

void mymodel::ChangeSelectedToRx()
{
    QModelIndexList selectedItemList = ui->tableView->selectionModel()->selectedIndexes();
    foreach(QModelIndex itemIndex, selectedItemList)
    {
        moniterFilterModel->setData(itemIndex, QVariant("R"));    }
}

void mymodel::DisableMonitoringForSelectedItems()
{
    QModelIndexList selectedItemList = ui->tableView->selectionModel()->selectedIndexes();
    foreach(QModelIndex itemIndex, selectedItemList)
    {
        moniterFilterModel->setData(itemIndex, QVariant(".."));
    }
}

what am i missing ?

Hi,

What problem are you experiencing ? By the way, why don't you use position when executing your context menu ?

On a side note, you are currently leaking memory, each time your slot is called, you recreate everything.

how to use postion when execulting context menu ?

Ratzz

I added below code to make it worked .

    ui->TableView->setContextMenuPolicy(Qt::CustomContextMenu);

SGaist

For the position thing, just use it in place of calling QCursor::pos()

Glad you found out, don't forget to update the thread title prepending [solved] so other forum users may know a solution has been found :)
