145=head2 Extension Objects
146
147Very perl extension is a perl class. A separate perl object is created
148for each terminal and each extension and passed as the first parameter to
149hooks. So extensions can use their C<$self> object without having to think
150about other extensions, with the exception of methods and members that
151begin with an underscore character C<_>: these are reserved for internal
152use.
153
154Although it isn't a C<urxvt::term> object, you can call all methods of the
155C<urxvt::term> class on this object.
156
157It has the following methods and data members:

167
168Dynamically enable the given hooks (named without the C<on_> prefix) for
169this extension, replacing any previous hook. This is useful when you want
170to overwrite time-critical hooks only temporarily.

127object that is shared between all packages is stored in the C<term>
128member. It is, however, blessed intot he package of the extension script,

1324=item $success = $term->grab_button ($button, $modifiermask)
1325
1326Registers a synchronous button grab. See the XGrabButton manpage.
1327
1328=item $success = $term->grab ($eventtime[, $sync])
1329
1330Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
1331synchronous (C<$sync> is true). Also remembers the grab timestampe.
1332
1333=item $term->allow_events_async
1334
1335Calls XAllowEvents with AsyncBoth for the most recent grab.
1336
1337=item $term->allow_events_sync
1338
1339Calls XAllowEvents with SyncBoth for the most recent grab.
1340
1341=item $term->allow_events_replay
1342
1343Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for the most
1344recent grab.
1345
1346=item $term->ungrab
1347
1348Calls XUngrab for the most recent grab. Is called automatically on
1349evaluation errors, as it is better to lose the grab in the error case as
1350the session.
