## Detailed Description

## Property Documentation

### accepted : bool

Setting accepted to `true` prevents the key event from being propagated to the item's parent.

Generally, if the item acts on the key event then it should be accepted so that ancestor items do not also respond to the same event.

Access functions:

bool | isAccepted() const
void | setAccepted(bool accepted)

### `[read-only]` count : const int

Holds the number of keys involved in this event. If text is not empty, this is simply the length of the string.

Access functions:

int | count() const

### `[read-only]` isAutoRepeat : const bool

Holds whether this event comes from an auto-repeating key.

Access functions:

bool | isAutoRepeat() const

### `[read-only]` key : const int

This property holds the code of the key that was pressed or released.

See Qt.Key for the list of keyboard codes.

See also QKeyEvent::key().

Access functions:

int | key() const

### `[read-only]` modifiers : const int

This property holds the keyboard modifier flags that existed immediately before the event occurred.

See also QKeyEvent::modifiers().

Access functions:

int | modifiers() const

### `[read-only]` nativeScanCode : const quint32

This property contains the native scan code of the key that was pressed. It is passed through from QKeyEvent unchanged.

Access functions:

quint32 | nativeScanCode() const

### `[read-only]` text : const QString

This property holds the Unicode text that the key generated. The text returned can be an empty string in cases where modifier keys, such as Shift, Control, Alt, and Meta, are being pressed or released. In such cases key will contain a valid value.

Access functions:

QString | text() const

## Member Function Documentation

### `[invokable]` bool QKeyEvent::matches(QKeySequence::StandardKey key_) const

Returns `true` if the key event matches the given standard key key_; otherwise returns `false`.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

See also QKeySequence::StandardKey.

### QEvent::Type QKeyEvent::type() const

Returns the type of the event.

### QKeyEventPtr

A shared pointer for QKeyEvent.
