Class “Popover”

Object > NativeObject > Popup > Popover

An Popover represents a modal ui container that is shown above the apps content. It provides the root element of a new layout hierarchy in the form of its contentView property. User provided widgets can be attached to the contentView similarly to the tabris.contentView. In order to close the Popover the close() method can be used.

The appearance of the Popover depends on the device size: On larger devices (like tablets) the Popover is shown as a floating window whereas on smaller devices it is shown as a fullscreen sheet covering the entire app.
