Also in this case, the operating system detects rotation of the device and automatically orders the
application to repaint its user interface.
Important As it turns out, full-screen rotations may require some adjustments to the over-
all user interface of the application. It is not unusual that some content originally designed
to extend horizontally needs be reorganized so that it also looks great on a device held in
portrait mode. The operating system doesn't handle this aspect for you. All the operating
system does is let the application know about view changes and ordering a repaint.
The user can turn in the snapped state one of the applications that is currently running in the
background. As a user, you pop up the switch list on the left side of the device and right-click the tile
of the application of choice. As Figure 8-1 shows, you can decide to snap the application to the left or
the right edge.
FIGURE 8-1 Turning a background application into the snapped state.
The result of this action is shown in Figure 8-2. When snapping is on, one application is said to
be snapped; the other application previously running in full-screen mode is turned into a view state
named filled. .
