[Solved] Cancelable dowloading dialog?
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 ()
void QNetworkReply::close ()
Read about them in Assistant, they are slightlty different.
I'm having problems connecting the QNetworkReply signal.
QNetworkReply *reply = manager->post(request, data);
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
