@karti-gesar
Is it QDialog from Cpp and are you talking about QQuickView or QQuickWidget?
How did you call QQuickView from QDialog ?

[karti gesar]

dialog in cpp and Qtquick in qml

[karti gesar]

view =new QQuickView();
view->setSource(QUrl("qrc:/icons/main.qml"));
imgsource<<"file:///E:/additional's/file4.jpg";
view->show();
when button is pressed this some or this will shown

[karti gesar]

image will be shown in qml window

[karti gesar]

my question is when press any key in qml i want to get that dialog window

[karti gesar]

Keys.onPressed: {
if (event.modifiers & Qt.ControlModifier)
{
console.log("qml");
//when press any here i want to hide the view window
}

@karti-gesar If I understood you correctly you want a way to close the QQuickView window using the Keys item in the QML loaded by that QQuickView. If so then there is a global Qt object that provides a quit method. As its description says you just have to connect that signal to your QQuickView's QQmlEngine and then call close on QQuickView.
Eg.
QML

Keys.onPressed: {
  ...
  Qt.quit()
  ...
}

CPP

view =new QQuickView;
connect(view->engine(), SIGNAL(quit()), view, SLOT(close()));
or
connect(view->engine(), &QQmlEngine::quit, view, &QQuickView::close);

Hope this helps...

@karti-gesar No. It is the global object available across all QML files.
