Could you post a minimal compilable example which reproduces the problem?

[patrik08]

I attach file...
here ist the small drag in url to qtextedit ...
and a.arguments() that fail on mac on main && drag in on kde (only kde)

you can self use the apps to read this 3 file

main.cpp
openmyfile.cpp
openmyfile.h
drag_test.pro

qmake && make & find apps on ....

TARGET = dragfile
win32 {
DESTDIR	+= ./
}
unix {
DESTDIR	+= ~/Desktop
}
mac {
DESTDIR	+= /Applications
}

TARGET = dragfile
win32 {
DESTDIR	+= ./
}
unix {
DESTDIR	+= ~/Desktop
}
mac {
DESTDIR	+= /Applications
}

Is it really a minimal compilable example?

So what is the incorrect behaviour? It seems to work correctly for me (KDE 3.5.4) I drag the file onto the label, drop it and its contents appear in the text box below.

BTW. Placing files on peoples' desktops is not something I'd call "nice". Please try to avoid it next time when posting an example.

on my KDE not running ... kubuntu qt4.1 packace from debs url

it display inside qtextedit "file:///path/blabla.xx"... as text not read inside

i suppose toLocalFile(); is os different....

void OpenMyFile::Grabdata(const QMimeData *data)
{
  if (!data) {
    return;
  }
   QList<QUrl> urlelist;
    if (data->hasUrls()) {
      urlelist = data->urls(); 
      for ( int i = 0; i < urlelist.size(); ++i ) { 
          QString unfilone = urlelist.at(i).toLocalFile();
          /////qDebug() << "### url  " << unfilone;
          QFile f(unfilone);
          if (f.exists()) {
          OpenFile(unfilone);
          }
 
      }
  }
}

          QString unfilone = urlelist.at(i).toLocalFile();
          /////qDebug() << "### url  " << unfilone;
          QFile f(unfilone);
          if (f.exists()) {
          OpenFile(unfilone);
          }

You're dropping on a wrong widget. The text edit has its own drop handler which is displaying text carried by the drag and it happens that URLs are stored as text, so it's a perfectly good drag for the text edit, so it handles the event and doesn't pass it to a parent widget where your drop handler resides. Try dropping outside the text edit.

Of course it's os specific, but toLocalFile() doesn't have anything to do here - it's not even called when you drop on the text edit.

Or from the C++ Gui programming Book

Suppose the QTextEdit is inside a main Window then

MainWindow::MainWindow( ... ){
[...]
      textEdit->setAcceptDrops( false );
      setAcceptDrops( true );
}
 
void MainWindow::dragEnterEvent( QDragEnterEvent *e ) {
   // accept if  you can decode the mime data
}
 
void MainWindow::dropEvent( QDropEvent *e ) {
  // get the file from the mime Data
  readFile( file );
}

MainWindow::MainWindow( ... ){
[...]
      textEdit->setAcceptDrops( false );
      setAcceptDrops( true );
}

void MainWindow::dragEnterEvent( QDragEnterEvent *e ) {
   // accept if  you can decode the mime data
}

void MainWindow::dropEvent( QDropEvent *e ) {
  // get the file from the mime Data
  readFile( file );
}
