/**
 * @short A push button that looks like a keyboard key.
 *
 * You must call setShortcut() to set the widget's currently displayed key.
 * You can call captureShortcut() to get a new shortcut from the user.
 * If captureShortcut() succeeds, then the capturedShortcut() signal will be
 * emitted with the value of the new shortcut.  The widget containing
 * a KKeyButton widget must connect to this signal and check if the shortcut
 * is valid.  If it is, you will need to call setShortcut() with the new
 * value in order make it the key currently displayed.
