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.
另请参阅 QKeySequenceEdit::keySequence .
This property contains the currently chosen key sequence.
The shortcut can be changed by the user or via setter function.
