QNetworckAccessManager & Connecting
-
Hi,
I want to download a list of icons for the items of my QStandardItemModel (appsModel). when I do this it does nothing:void MainWindow::downloadIcons()
{
for (int i=0; i<appsModel->rowCount(); ++i)
{
QUrl iconUrl("https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png");QNetworkRequest request(iconUrl); QNetworkAccessManager *tempManager = new QNetworkAccessManager; tempManager->get(request);
connect(tempManager,SIGNAL(finished(QNetworkReply*)),this,SLOT(setDownloadedIcons(QNetworkReply*)));
}
}for now the link is the google image but I will set it to the data of items of my model. It's just for testing. what am I doing wrong?

Hi,
You should also connect the error signal
By the way, why are you re-creating a new QNetworkAccessManager each time ?

Hi, @SGaist
My code doesn't work. I can't see how the problem is related to connecting the error signal. can you explain?And also What do you mean by one QNetworkAccessManager? How can I do that?

That would allow you to know that something wrong happened by at least printing the error on the console.
I mean don't recreate one each time you send a request. Currently you also have a memory leak since you never delete them.
Just add one as a member of your MainWindow class and use it to send all the requests.
