Using WebChannel and WebEngine IPC to get access to QtObjects from HTML

dominator

Hi all,

I'm trying to establish a connection between the HTML and QtQuick Application. On the QML Side I create an QtObject and add it to the WebChannel

QtObject{
        id: rotateID
        WebChannel.id: "rotateJS"

        function screenOrientation(value){
            //do something
        }
    }

WebEngineView {
        id: webEngine
        WebChannel{
               id: testobject
               registeredObjects: [rotateID]
               }
    }

Inside the HTML I'm using the qwebchannel.js and try to call this function

new QWebChannel(qt.webChannelTransport, function (channel) {
      channel.rotateJS.screenOrientation("portrait");
    });

Unfortunately it seems that the communction via the WebEngine IPC doesn't work. Does anyone have experience with this?

Best,

you can check if there are any javascript errors on the console.

I found the problem.

You have to set the webChannel property of the WebEngineView

WebEngineView {
        id: webEngine
       webChannel: testobject
        
    }
WebChannel{
       id: testobject
       registeredObjects: [rotateID]
    }
