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.
访问函数:
| bool | isAccepted() const |
| void | setAccepted(bool accepted) |
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.
访问函数:
| int | count() const |
isAutoRepeat : const bool
Holds whether this event comes from an auto-repeating key.
访问函数:
| bool | isAutoRepeat() const |
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.
访问函数:
| int | key() const |
参见 QKeyEvent::key.
modifiers : const int
This property holds the keyboard modifier flags that existed immediately before the event occurred.
访问函数:
| int | modifiers() const |
参见 QKeyEvent::modifiers.
nativeScanCode : const quint32
This property contains the native scan code of the key that was pressed. It is passed through from QKeyEvent unchanged.
访问函数:
| quint32 | nativeScanCode() const |
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.
访问函数:
| QString | text() const |
成员函数
QKeyEvent::QKeyEvent(QEvent::Type type, int key, Qt::KeyboardModifiers modifiers, const QString &text = QString(), bool autorep = false, ushort count = 1)
Default constructs an instance of QKeyEvent.
QKeyEvent::QKeyEvent(const QKeyEvent &ke)
Copy constructor.
bool QKeyEvent::matches(QKeySequence::StandardKey key_) const
Returns true if the key event matches the given standard key key_; otherwise returns false.
QEvent::Type QKeyEvent::type() const
Returns the type of event
