Camera:onCreate()

Camera:onCreate()event

widget only

This event is only available when the ui module is loaded before capture and Camera is used as a widget.

This event is fired when the Camera widget has just been created, right after the constructor returns. It is a good place to initialize widget properties.

Return value

The event returns no value.
