Detailed Description
QKeyEvent event type send by KeyBoardHandler.
Contains parameters that describe a key event
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) |
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 |
isAutoRepeat : const bool
Holds whether this event comes from an auto-repeating key.
Access functions:
| 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.
Access functions:
| int | key() const |
See also QKeyEvent::key.
modifiers : const int
This property holds the keyboard modifier flags that existed immediately before the event occurred.
Access functions:
| int | modifiers() const |
See also 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.
Access functions:
| 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.
Access functions:
| QString | text() const |
Member Function Documentation
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.
See also QKeySequence::StandardKey.
QEvent::Type QKeyEvent::type() const
Returns the type of event
