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.

[read-only] count : int

Holds the number of keys involved in this event. If text is not empty, this is simply the length of the string.

[read-only] isAutoRepeat : bool

Holds whether this event comes from an auto-repeating key.

[read-only] key : int

This property holds the code of the key that was pressed or released.
