Overlaying the Qt form window on the Qml window

Aravinth Ravi

Hi,

I have overlaid the Qt form window on the Qml window. When I trigger the application, both the windows were displayed on the screen simultaneously, in such a way that, form window overlaid on the Qml window.

But when I implement the signal slot connection between the form window and Qml window, both the windows were not displaying on the screen simultaneously, Qml window is displayed and form window is minimized and the icon is displaying on the taskbar. When I click on the icon, form window is getting overlaid on the Qml window.

When there is no signal slot connection, both the windows were displayed simultaneously.(Signal in Qml window and slot in form window) And also when I trigger any components in Qml window, the overlaid form window is getting minimized.

Everytime when I trigger the application, both windows has to open simultaneously and none of the window has to be minimized, when I trigger any components.

Provide some inputs to sort out this issue. Thanks in advance.

Hi @dheerendra ,

This is my sample code, for your reference,
int main(int argc, char *argv[])
{
#if defined(Q_OS_WIN)
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif

QGuiApplication app(argc, argv);


QApplication a(argc, argv);
QScreen *screen = QGuiApplication::primaryScreen();
MainWindow w;
int ScreenGeometry_width = screen->geometry().width();
int ScreenGeometry_height = screen->geometry().height();
w.move(100,100);
w.setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
w.resize(ScreenGeometry_width-120,ScreenGeometry_height-120);
w.show();

QQmlApplicationEngine engine1;
QQmlComponent component(&engine1, QUrl(QLatin1String("qrc:/main.qml")));
QObject *mainPage = component.create();

QObject* item1 = mainPage->findChild<QObject *>("button2");



QObject::connect(item1, SIGNAL(clickedButton1(QString)), &w, SLOT(onButtonClicked1(QString)));

return app.exec();

}
