[Solved] Cancelable dowloading dialog?

[zolakt]

Hi,

I'm developing an app for Maemo. The app downloads some audio files from the server.
As the data downloads I would like to show the loading dialog.
Also I'd like it to have a "Cancel" button, which will stop the downloading if clicked.

Is there any way to bind the downloading directly to the dialog, or do I have to implement threading myself?

You should implement cancellation by yourself. It will be not hard. Just close the connection and collect garbage.

Any example maybe?
Currently I'm only sending a request to QNetworkAccessManager.
I'm running an event loop to ensure synchronous reply.

Other thing, is there any way to display progress data of downloading. Example. 0.2/1.3mb

To get progress info you can use signal
@
void QNetworkReply::downloadProgress ( qint64 bytesReceived, qint64 bytesTotal )
@

For cancellation you can use either
@
void QNetworkReply::abort ()
@
or
@
void QNetworkReply::close ()
@

Read about them in Assistant, they are slightlty different.

I'm having problems connecting the QNetworkReply signal.

My code:
@
QNetworkReply *reply = manager->post(request, data);
QObject::connect(reply, SIGNAL(downloadProgress(qint64,qint64)),
this, SLOT(downProg(qint64,qint64)))
@

Gives an error:
no matching function to call to 'QObject:connect(QNetworkReply*&, const char*, MyClass* const, const char*)'
candidates are: static bool QObject::connect(const QObject*, const char*, const QObject*, const char*, Qt:ConnectionType)'

got it working
forgot to derive myClass from QObject

thanks a lot for your help
