+    Adds the PM event filter to this widget. This is functionally equivalent to
+    overriding the QWidget::pmEvent() virtual method.
+
+    Note that the event filters added with this method are called before
+    QWidget::pmEvent() and may prevent Qt from further event processing
+    including passing it to QWidget::pmEvent(). The order in which these filters
+    are called corresponds to the order they are added to this widget.
