116=item $string
117
118A perl text string, with an emphasis on I<text>. It can store all unicode
119characters and is to be distinguished with text encoded in a specific

189 222
223=item on_add_lines $term, $string
224
225Called whenever text is about to be output, with the text as argument. You
226can filter/change and output the text yourself by returning a true value
227and calling C<< $term->scr_add_lines >> yourself. Please note that this
228might be very slow, however, as your hook is called for B<all> text being
229output.
230
231=item on_line_update $term, $row
232
233Called whenever a line was updated or changed. Can be used to filter
234screen output (e.g. underline urls or other useless stuff). Only lines
235that are being shown will be filtered, and, due to performance reasons,
236not always immediately.
237
238The row number is always the topmost row of the line if the line spans
239multiple rows.
240
241Please note that, if you change the line, then the hook might get called
242later with the already-modified line (e.g. if unrelated parts change), so
243you cannot just toggle rendition bits, but only set them.

265does focus in processing.

286Called whenever the corresponding X event is received for the terminal If
287the hook returns true, then the even will be ignored by rxvt-unicode.
288
289The event is a hash with most values as named by Xlib (see the XEvent
290manpage), with the additional members C<row> and C<col>, which are the row
291and column under the mouse cursor.

604The sole purpose of this class is to deliver an interface to the
605C<AnyEvent> module - any module using it will work inside urxvt without
606further work. The only exception is that you cannot wait on condition
607variables, but non-blocking condvar use is ok. What this means is that you
608cannot use blocking APIs, but the non-blocking variant should work.
