QTextEdit's dropEvent always append "file:///XXXXXXXXXXXX" to the end of QTextEdit

Soul

I wan't to drag a file to the text edit and open it in the background.
But when I drag the file into text edit, the text edit always append "file:///XXXXXXXXXXXX" to the end of it.
Is there any way to solve the problem ? Please help.

The code is shown below:


void ConsoleEdit::dropEvent(QDropEvent *e)
{
    QFileInfo file(e->mimeData()->text());

    if(file.suffix().contains("Bin") ||\
            file.suffix().contains("bin") ||\
            file.suffix().contains("BIN")){
        qDebug("support file\r\n");

        if(pFile->isOpen()){
            pFile->close();
        }
        else{
            pFile->setFileName(e->mimeData()->urls().first().toLocalFile());
            if(pFile->open(QIODevice::ReadOnly)){
                emit newBinFileDragInEvent();
                //appendInfo("New file opened\r\n");
            }
        }
    }
    else{
        appendInfo("Unsupport file .\r\n", INFO_TYPE_ERR);
    }

    QTextEdit::dropEvent(e);
}

@Soul
something like this:

bool MyTextEdit::canInsertFromMimeData(const QMimeData *source) const
{
      return source->hasUrls() || QTextEdit::canInsertFromMimeData(source);
}

void MyTextEdit::insertFromMimeData(const QMimeData *source)
{
    if (source->hasUrls())
    {
        QFile file (source->urls().first().toLocalFile());
        if ( file.open(QIODevice::ReadOnly) )
        {
            QTextStream in( &file );
            this->setPlainText( in.readAll() );
            return;
        }
   }
   QTextEdit::insertFromMimeData(source);
}

Hi Raven, Thanks for you replying.
I tryed the code you had given to me. But I think it still can not prevent the dropEvent insert "file:///XXXX" to the end.
Can I pass something NULL-Event to the QTextEdit::dropEvent() ？

@Soul said in QTextEdit's dropEvent always append "file:///XXXXXXXXXXXX" to the end of QTextEdit:

QTextEdit::dropEvent(e);

I would guess the default implementation just reads the url from the QMimeData and appends it to the QTextEdit. Try to simply not call the base implementation to avoid this.

do you think or do you know?
I haven't tested my code, but if there are urls in the mime data they are inserted before any other data (like text).

@Christian-Ehrlicher Yes it's the reason. But when I do not call the QTextEdit::dropEvent(e), the text cursor is frozened after I drag the file into text area.
