Drag and drop bug in Linux?

[hbatalha]

I am using a Linux Mint 20.1 to test my app in a linux environment and for some reason the drag and drop for text is not working as the mimeData()->text() is always empty.

This is the code used to enable the drag and drop.

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    this->setAcceptDrops(true);

//...
}

void MainWindow::dragEnterEvent(QDragEnterEvent *event)
{
    if(event->mimeData()->hasFormat("text/plain"))
    {
        event->acceptProposedAction();
    }
}

void MainWindow::dropEvent(QDropEvent *event)
{
    if( ! isProcessingLink)
    {
        qDebug() << event->mimeData()->text(); // empty
        processLink(event->mimeData()->text());
    }

    event->acceptProposedAction();
}

On windows this works fine but in linux there's no text.

I am using Qt 6.2.0

Hi,

Did you check the type of the mime data you are getting ?

[hbatalha]

@SGaist I checked if it has text and it returned true.

[SGaist]

That wasn't my question. What are the types that have been registered in the mine data object ? There might be a difference there.

[hbatalha]

@SGaist I don't know how to verify that.

[SGaist]

QMimeData::formats.

[hbatalha]

@SGaist This is what I get when I run

qDebug() << event->mimeData()->formats();

QList("text/plain", "_NETSCAPE_URL", "chromium/x-renderer-taint", "text/html", "text/uri-list")

[SGaist]

Did you check what QMimeData::data returns for each type ?

[hbatalha]

@SGaist Sorry for the late reply

I did that and it returned everything ok for each type. So I did this:

processLink(event->mimeData()->data("text/plain"));

And it is working great. I don't know why mimeData()->text() is returning empty, can it be a bug?
