设置

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 ) |
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 |
Holds whether this event comes from an auto-repeating key.
访问函数:
bool | isAutoRepeat () const |
This property holds the code of the key that was pressed or released.
见 Qt.Key for the list of keyboard codes.
另请参阅 QKeyEvent::key ().
访问函数:
int | key () const |
This property holds the keyboard modifier flags that existed immediately before the event occurred.
另请参阅 QKeyEvent::modifiers ().
访问函数:
int | modifiers () const |
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 |
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 |
返回
true
if the key event matches the given standard key
key_
;否则返回
false
.
注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .
另请参阅 QKeySequence::StandardKey .
Returns the type of the event.
