save QPixmap asynchronously

[atonical]

Hi,

I use the following codes to save a QPixmap, while it does really saves, it actually makes my app pause a little, probably due the the amount of data to be written is large.

Therefore, I would like to find out how can i save a image asynchronously such that my app will not "hang"?

                baTemp.append(recvStringModified);
                ba.append(QByteArray::fromBase64(baTemp));

                QPixmap *aPicmap2=new QPixmap();
                qDebug()<<ba.size();
                bool status1=aPicmap2->loadFromData(ba);
      

                qDebug()<<"saving image....";
                bool status2=aPicmap2->save("/home/user/MyDocs/DCIM/filename.png");

Any help is appreciated. Thanks!

Hi,
You can put the code you want to run asynchronously in a new QObject sublcass and then run it in a separate thread as
shown in the following example [1].
