    @sankarapandiyan said in The ProgressBar doesnt close Properly: popup_progress->setValue(popup_progress->value()+1); int value = popup_progress->value() + 1; popup_progress->setValue(value); Why do you set the value twice?! Lets say popup_progress->value() is 99, then: popup_progress->setValue(popup_progress->value()+1); // here you set it to 100 int value = popup_progress->value() + 1; // value is 101 now popup_progress->setValue(value); // you set 101 here So, value is never 100 in my example!

    To extend @LeLev answer a bit, the easiest way is to initiate QNetworkAccessManager and use one of its methods (put or post, probably, you can also use custom if those two don't exactly fit). Documentation on QNetworkAccessManager

    @AnatoliyS said in QPA: memory leaks in platform integrations like qminimal and others: But it doesn't work, because deleting forward-declared object lead to unpredicted behaviour Can you explain this? QScreen has a virtual dtor so I don't see any problem here. And since you instantiate QMinimalIntegration only once it's not much of a problem (although it should be fixed - please create a bug report about this).
