@Pradeep-Reddy ,

Item {
focus: true
Keys.onPressed: {
console.log(event.key)
if (event.key === Qt.Key_Back) {
mainWindow.showMinimized();
event.accepted = true;
}
}
}
It wont work, but it will print key value.
something like 16777219.
I used this value to compare with event key.
It worked
if (event.key === 16777219) {
mainWindow.showMinimized();
}
