| 33 | When a key is pressed or released, a key event is generated and delivered to the
|
|---|
| 34 | focused QML \l Item. To facilitate the construction of reusable components
|
|---|
| 35 | and to address some of the cases unique to fluid user interfaces, the QML items add a
|
|---|
| 36 | \e scope based extension to Qt's traditional keyboard focus model.

|

| 41 |
|
|---|
| 42 | When the user presses or releases a key, the following occurs:
|
|---|
| 43 | \list 1
|
|---|
| 44 | \o Qt receives the key action and generates a key event.
|
|---|
| 45 | \o If the Qt widget containing the \l QDeclarativeView has focus, the key event
|
|---|
| 46 | is delivered to it. Otherwise, regular Qt key handling continues.
