Detailed Description
This widget lets the user choose a QKeySequence, which is usually used as a shortcut. The recording is initiated when the widget receives the focus and ends one second after the user releases the last key.
See also QKeySequenceEdit::keySequence.
Property Documentation
[since 6.4] clearButtonEnabled : bool
This property holds whether the key sequence edit displays a clear button when it is not empty.
If enabled, the key sequence edit displays a trailing clear button when it contains some text, otherwise the line edit does not show a clear button (the default).
This property was introduced in Qt 6.4.
Access functions:
| bool | isClearButtonEnabled() const |
| void | setClearButtonEnabled(bool enable) |
[since 6.5] finishingKeyCombinations : QList<QKeyCombination>
This property holds the list of key combinations that finish editing the key sequences.
Any combination in the list will finish the editing of key sequences. All other key combinations can be recorded as part of a key sequence. By default, Qt::Key_Tab and Qt::Key_Backtab will finish recording the key sequence.
This property was introduced in Qt 6.5.
Access functions:
| QList<QKeyCombination> | finishingKeyCombinations() const |
| void | setFinishingKeyCombinations(const QList<QKeyCombination> &finishingKeyCombinations) |
keySequence : QKeySequence
This property contains the currently chosen key sequence.
The shortcut can be changed by the user or via setter function.
Note: If the QKeySequence is longer than the maximumSequenceLength property, the key sequence is truncated.
Access functions:
| QKeySequence | keySequence() const |
| void | setKeySequence(const QKeySequence &keySequence) |
Notifier signal:
| void | keySequenceChanged(const QKeySequence &keySequence) |
[since 6.5] maximumSequenceLength : qsizetype
This property holds the maximum sequence length.
The maximum number of key sequences a user can enter. The value needs to be between 1 and 4, with 4 being the default.
This property was introduced in Qt 6.5.
Access functions:
| qsizetype | maximumSequenceLength() const |
| void | setMaximumSequenceLength(qsizetype count) |
Member Function Documentation
[explicit] QKeySequenceEdit::QKeySequenceEdit(QWidget *parent = nullptr)
Constructs a QKeySequenceEdit widget with the given parent.
[explicit] QKeySequenceEdit::QKeySequenceEdit(const QKeySequence &keySequence, QWidget *parent = nullptr)
Constructs a QKeySequenceEdit widget with the given keySequence and parent.
[virtual noexcept] QKeySequenceEdit::~QKeySequenceEdit()
Destroys the QKeySequenceEdit object.
[slot] void QKeySequenceEdit::clear()
Clears the current key sequence.
[signal] void QKeySequenceEdit::editingFinished()
This signal is emitted when the user finishes entering the shortcut.
Note: there is a one second delay before releasing the last key and emitting this signal.
