QEvent::Drop not called

jmoriarty

Here is a sample code of what I a trying to do! When I run it QEvent::Drop is never called! I even tried using viewport() and writing a piece including dragMove but nothing works.

setAcceptDrops is true for both MainWindow and ui->EditorMdiArea

Help is much needed!

Thank You

bool MainWindow::eventFilter(QObject *pFilterObj, QEvent *event) {
    if((pFilterObj==ui->EditorMdiArea) && (event-type()==QEvent::Drag)) {
         QDragEnterEvent *devent = (QDragEnterEvent*)event;
         qDebug()<<"Here we are 1";
            devent->acceptProposedAction();
            devent->accept();
    }
    //if((pFilterObj==ui->EditorMdiArea) && (QVariant(event->type()).toString()=="61")) {
    //  QDragEnterEvent *devent = (QDragEnterEvent*)event;
    //   qDebug()<<"Here we are 2";
    //  devent->accept();
    //}
    qDebug()<<"pFilterObj is "<<pFilterObj;
    qDebug()<<"event type is "<<event->type();
    //ui->EditorMdiArea->viewport()->installEventFilter(this);
    //ui->EditorMdiArea->viewport()->setAcceptDrops(true);

    if((pFilterObj==ui->EditorMdiArea) && (Qevent->type()==QEvent::Drop)) {
        qDebug()<<" Inside pFilterObj is "<<pFilterObj;
    qDebug()<<"Inside event type is "<<event->type();
        QDropEvent *devent = (QDropEvent*)event;
          qDebug()<<"Finaly Destination Reached";
            }
        }
    }
    }
    return false;
}

No! But I got the catch. I just added return true in the if block of QEvent::Drag and it worked like a charm! Thanks @SGaist

Hi and welcome to devnet,

How did you setup the event filter ?
What are you trying to drop ?

@SGaist Hello! I am trying to drop a file in the ui->EditorMdiArea so as to open it o drop!
For setting up the event filter I have done the following ui->EditorMdiArea->installEventFilter(this); ui->EditorMdiArea->setAcceptDrops(true); in the constructor of the MainWindow
