QWebView does not display the map

Mikeeeeee

Hi!
I'm trying to open the map in QWebView , but when you start the program crashes. Please tell me how to fix it.

import QtQuick 2.12
import QtQml 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12
import QtWebView 1.13

Item {
    width: 400
    height: 650
    visible: true
    WebView {
        anchors.fill: parent
        url: "https://m.yandex.ru/maps"
    }

}

Hi,

What Qt version ?
What OS ?
Run it through the debugger and show the stack trace.

Mikeeeeee

Qt 5.13
OS: Windows 7 64 bit pro and Android 6
And you have this code normally opens map?
Debuger get this:

@Mikeeeeee said in QWebView does not display the map:

Debuger get this

How about using a debug build instead of release?

Mikeeeeee

Found a strange bug: when compiling for Windows, you need to stretch the window to the right, then the map will appear. How can this be corrected? And under Android does not compile. Why?

No idea, my crystal ball is broken.
What about giving more information, like errors you get?

Faced almost the same issue on a Video Player project. Try to fix the resolution, and have a trial-error on the resolution variables :D

Mikeeeeee

But I have built pixel-by-pixel website in WebView. I have no video and no resolution setting either.
