}

QDirModel *dirMod = (QDirModel *)(localDir->model());
bool selectedIsDir = dirMod->fileInfo( localDir->currentIndex() ).isDir();
QString path = dirMod->fileInfo( localDir->currentIndex() ).absoluteFilePath();

if(selectedIsDir)
{
QFile *file = new QFile(path + "/" + fileName);

ftp->get(fileName, file);
stopAction->setEnabled(true);
down=new MyTreeWidgetItem;
currentDown[ ftp->currentId() ] = down;
connect( ftp, SIGNAL( dataTransferProgress(qint64, qint64) ), currentDown[ ftp->currentId() ] , SLOT( progressTranferDataSlot(qint64, qint64) ) );
listDown->addTopLevelItem( currentDown[ ftp->currentId() ] );
currentDown[ ftp->currentId() ]->setLine(1, fileName);

dirMod->refresh();

The dir model shows its size as 0 or its also empty on the disk? Have you tried checking QFtp::error() and/or QFtp::errorString()?

thanks

in the dir model the size of files isn't 0, but dont have the real size, it have size less than the real size (for example: real size : 79 KB, size in dir model 64KB) :crying:

QFtp::error() (http://doc.trolltech.com/latest/qftp.html#error) return 0 .

What actions do you take when the download finishes?

What actions do you take when the download finishes?




connect( ftp, SIGNAL( commandFinished (int, bool) ), this, SLOT( cmdFinishedSlot(int, bool) ) );

//...

void myMainWindow::cmdFinishedSlot(int cmd, bool error)
{
toParentServer->setEnabled(true);
toRootServer->setEnabled(true);
refreshServer->setEnabled(true);
newDirServer->setEnabled(true);
deleteDirFile->setEnabled(true);
renameFile->setEnabled(true);

downFile->setEnabled(true);
upFile->setEnabled(true);

stopAction->setEnabled(false);

setCursor(Qt::ArrowCursor);

if ( ftp->currentCommand() == QFtp::Get || ftp->currentCommand() == QFtp::Put )
{
disconnect( ftp, SIGNAL( dataTransferProgress(qint64, qint64) ), currentDown[ ftp->currentId() ] , SLOT( progressTranferDataSlot(qint64, qint64) ) );
if ( ftp->currentCommand() == QFtp::Put )
{
serverDir->clear();
currentServerDir.clear();
ftp->list();
}
else
{
QDirModel *dirMod = (QDirModel *)(localDir->model());
dirMod->refresh();
}
}
}


I try to do just


void myMainWindow::cmdFinishedSlot(int cmd, bool error)
{
toParentServer->setEnabled(true);
toRootServer->setEnabled(true);
refreshServer->setEnabled(true);
newDirServer->setEnabled(true);
deleteDirFile->setEnabled(true);
renameFile->setEnabled(true);

downFile->setEnabled(true);
upFile->setEnabled(true);

stopAction->setEnabled(false);

setCursor(Qt::ArrowCursor);
}

and i have the same problem

Hmm, is the file closed and/or the QFile object destructed anywhere?

in th

void myMainWindow::cmdFinishedSlot(int cmd, bool error)
I delete the QFile* in
