Showing a busy indicator or a loading image while loading large QML file

[x_d]

I'm working on a QML based app. where I dynamically load the content. However when running the application it takes quite a long time (5-10 secs), so I need to show any loading screen or indicator while the whole content is being loaded. Can anyone suggest me how to do it ?

For example, after I login in my application it took some time to load the next page so within that period of time i want to show the loading screen.

Truptimayee, 

Many samples have BusyIndicator QML, BusyIndicator QML Type | Qt Quick Controls 5.15.0, for example, the Analyze Viewshed sample, look at MyApp.qml around line 257 for BusyIndicator. 

Thank you,

Erwin.

Well my issue is when I redirect from one page to another on button click, then it takes quite a lot of time as i am loading data from server. So i want to redirect to next page quickly and then load all the content
