详细描述

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.

特性文档编制

[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 按钮 (当它包含一些文本时)，否则，行编辑不展示清零按钮 (默认)。

该特性在 Qt 6.4 引入。

访问函数：

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.

该特性在 Qt 6.5 引入。

访问函数：

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.

注意： 若 QKeySequence is longer than the maximumSequenceLength property, the key sequence is truncated.

访问函数：

QKeySequence keySequence () const
void setKeySequence (const QKeySequence & keySequence )

通知程序信号：

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.

该特性在 Qt 6.5 引入。

访问函数：

qsizetype maximumSequenceLength () const
void setMaximumSequenceLength (qsizetype count )

成员函数文档编制

[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 .

[虚拟] QKeySequenceEdit:: ~QKeySequenceEdit ()

销毁 QKeySequenceEdit 对象。

[slot] void QKeySequenceEdit:: clear ()

Clears the current key sequence.

[signal] void QKeySequenceEdit:: editingFinished ()

This signal is emitted when the user finishes entering the shortcut.

注意： there is a one second delay before releasing the last key and emitting this signal.

[override virtual protected] bool QKeySequenceEdit:: event ( QEvent * e )

重实现： QWidget::event (QEvent *event).

[override virtual protected] void QKeySequenceEdit:: focusOutEvent ( QFocusEvent * e )

重实现： QWidget::focusOutEvent (QFocusEvent *event).

[override virtual protected] void QKeySequenceEdit:: keyPressEvent ( QKeyEvent * e )

重实现： QWidget::keyPressEvent (QKeyEvent *event).

[override virtual protected] void QKeySequenceEdit:: keyReleaseEvent ( QKeyEvent * e )

重实现： QWidget::keyReleaseEvent (QKeyEvent *event).

[override virtual protected] void QKeySequenceEdit:: timerEvent ( QTimerEvent * e )

重实现： QObject::timerEvent (QTimerEvent *event).
