The LocalBusyIndicator can be used to disable single controls. It prevents the user from interacting with the control. This can be used if new data is loaded from the backend.
The LocalBusyIndicator is automatically added to Controls. It can be displayed by calling setBusy(true) on the control or element. It shows up after one second (standard behaviour). The delay can be changed by calling setBusyIndicatorDelay(ms) on the control.
