Hello everyone,
I'm developing a qt application in raspberry pi3 . The program includes a part which shows a special latitude and longitude on google maps (online). When running the program after loading the google map ( about 4 seconds) suddenly it crashes and shows "The program has unexpectedly finished."! here is the code I use to show the map :

ui->webView->setUrl(QUrl("https://www.google.com/maps/@30.2676303,57.0950032,16z"));

In addition, I used a try-catch to find the error when crashing, but the program doesnt go to catch part and shows nothing! This is my code with using try-catch :

try{
        ui->webView->setUrl(QUrl("https://www.google.com/maps/@30.2676303,57.0950032,16z"));
            }
    catch (...) {
          QMessageBox msgBox;
         msgBox.setText("something went wrong.");
           msgBox.exec();
    }

What QtWebKit version are you using?

In addition, I used a try-catch to find the error when crashing,

QtWebKit doesn't throw exceptions

![thanks for the respond,
actually I don't know the exact version of QTWebkit version but in "About QT Creator" section there're these information given:

Qt Creator 3.2.1
Based on Qt 5.3.2 (GCC 4.9.2, 32 bit)

Built on May 11 2016 at 17:13:20

If you can't recognise the QTWebkit version inside the above information, would you tell me how to find it myself please?

Regards.

@Konstantin-Tokarev
I found this command to identify the qtwebkit version, but not sure about it:

apt-cache policy libwebkitgtk-3.0-0

the output is :
libwebkitgtk-3.0-0:
Installed: 1:2.4.1-1rpi53rpi1g
Candidate: 1:2.4.1-1rpi53rpi1g
Version table:

@SGaist Can you help me with this case? I think QT 5.3 has a problem with Webview, then I plan to install qt5.12 (which I'm asking for help in another topic). what do you think bro?
thanks.
