Mouse ShortCut menu on DialogWindows?

Mucip

Hi,
Normally I use ShortCut Menu on Mainwindow like below code
In constructor:

ui->tVDetay->setContextMenuPolicy(Qt::CustomContextMenu);
           connect(ui->tVDetay, SIGNAL(customContextMenuRequested(const QPoint&)),
                      this, SLOT(ShowContextMenuTalep(const QPoint&)));

And the pordedure is:

void StokBilgiGiris::ShowContextMenuTalep(const QPoint& pos)
{
    QPoint globalPos = ui->tVDetay->mapToGlobal(pos);

    QMenu myMenuX;

    myMenuX.addAction("Stok Bilgisi Göster");


    QAction* selectedItem = myMenuX.exec(globalPos);

    // Hiçbir şey tıklanmazsa hata vermesin diye... :)

    if (selectedItem == nullptr) return;


    QModelIndex index;
    index = ui->tVDetay->currentIndex();


    if(!index.isValid())
    {
        QMessageBox::warning(this,"Seçim Hatası", "Seçili bir satır olması gerekir!");
        return;
    }  

    if (selectedItem->text() == "Stok Bilgisi Göster" )
    {

    }



}

But I don' know why Below line has error

QMenu myMenuX;

And teh error message is:

D:\Belgeler\Qt\CSI_Yonetim\stokbilgigiris.cpp:65: error: variable has incomplete type 'QMenu'
D:\ProgramFiles\Qt\5.10.1\msvc2017_64\include\QtWidgets\qlineedit.h:54: forward declaration of 'QMenu'

What is the problem?

Hi,

You are missing #include <QMenu>.

The incomplete type error means that you are missing the definition of the class which usually means that you didn't include the corresponding header.

Hi SGaist,
Thanks. Yes.
I confused because there isn't any error like missing library or like?

You won't have any linker error since the code cannot be compiled because of the missing include.
