Application crashes after fast load using ```Qt.createComponent```

Kiovtorov

Hi, I recently started using Qt.createComponent to dynamically load the pages in my application. example:

function onLogInSuccessful(username, fullName) {
                    var component = Qt.createComponent("Dashboard.qml");
                    if (component.status === Component.Ready) {
                        var signInWindow = component.createObject(null, { "usernameRef": username, "fullName": fullName }); // Pass the variable here
                        signInWindow.visible = true;
                        root.close();
                    } else {
                        console.log("Error loading Dashboard.qml: " + component.errorString());
                    }
                }

After some time of testing my program I found out that the program crashes without any given error (the window of the app hides but the app is running) and I have to forcefully close it. If that wasn't clear enough I would be happy to provide more info

Does it crash or hide ?
Does this happen after login ?
How about commenting root.close() ?

May be workable example will help.

If you are on WIndows and build with MIngw32 there is a nice a simple tool that use on test host,drmingw is save me in many time.

@dheerendra said in Application crashes after fast load using ```Qt.createComponent```:

The window hides. The app is still working but the window hides.
It happens no matter if it is a login or any other window opening with

var component = Qt.createComponent("Dashboard.qml");
                    if (component.status === Component.Ready) {
                        var signInWindow = component.createObject(null, { "usernameRef": username, "fullName": fullName }); // Pass the variable here
                        signInWindow.visible = true;
                        root.close();
                    } else {
                        console.log("Error loading Dashboard.qml: " + component.errorString());
                    }

not using root.close isn't doing me any good. the other window opens but the previous window is still open
