144
145Very perl extension is a perl class. A separate perl object is created
146for each terminal and each extension and passed as the first parameter to
147hooks. So extensions can use their C<$self> object without having to think
148about other extensions, with the exception of methods and members that
149begin with an underscore character C<_>: these are reserved for internal
150use.
151
152Although it isn't a C<urxvt::term> object, you can call all methods of the
153C<urxvt::term> class on this object.

162extension. This member I<must not> be changed in any way.
163
164=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
165
166Dynamically enable the given hooks (named without the C<on_> prefix) for
167this extension, replacing any previous hook. This is useful when you want
168to overwrite time-critical hooks only temporarily.
169

1264=item $success = $term->grab_button ($button, $modifiermask)
1265
1266Registers a synchronous button grab. See the XGrabButton manpage.
1267
1268=item $success = $term->grab ($eventtime[, $sync])
1269
1270Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
1271synchronous (C<$sync> is true). Also remembers the grab timestampe.
1272
1273=item $term->allow_events_async
1274
1275Calls XAllowEvents with AsyncBoth for the most recent grab.
1276
1277=item $term->allow_events_sync
1278
1279Calls XAllowEvents with SyncBoth for the most recent grab.
1280
1281=item $term->allow_events_replay
1282
1283Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for the most
1284recent grab.
1285
1286=item $term->ungrab
1287
1288Calls XUngrab for the most recent grab. Is called automatically on
1289evaluation errors, as it is better to lose the grab in the error case as
1290the session.
