-      Grabs are a method to claim all input events from a device,

-      or explicitly. Implicit grabs happen on user interaction, when
-      a #GdkEventButtonPress happens, all events from then on, until
-      after the corresponding #GdkEventButtonRelease, will be reported
-      to the widget that got the first event. Likewise, on touch events,

-      Explicit grabs happen programatically (both activation and
-      deactivation), and can be either system-wide (GDK grabs) or
-      application-wide (GTK grabs). On the windowing platforms that
-      support it, GDK grabs will prevent any interaction with any other
-      application/window/widget than the grabbing one, whereas GTK grabs

-      device is already grabbed. This makes it necessary for widgets to
-      handle the cancellation of any ongoing interaction. Depending on
-      whether a GTK or GDK grab is causing this, the widget will
