596 | =item $view_start = $term->view_start ([$newvalue]) |

599 | C<0>, which displays the normal terminal contents. Larger values scroll |

|
|
602 | =item $term->want_refresh |
|
|
603 | |
|
|
604 | Requests a screen refresh. At the next opportunity, rxvt-unicode will |
|
|
605 | compare the on-screen display with its stored representation. If they |
|
|
606 | differ, it redraws the differences. |
|

607 | |

|
|
610 | =item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
611 | |
|
|
612 | Returns the text of the entire row with number C<$row_number>. Row C<0> |
|
|
613 | is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost |
|
|
614 | terminal line. The scrollback buffer starts at line C<-1> and extends to |
|
|
615 | line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line |
|
|
616 | is requested. |
|
|
617 | |
|
|
618 | If C<$new_text> is specified, it will replace characters in the current |
|
|
619 | line, starting at column C<$start_col> (default C<0>), which is useful |
|
|
620 | to replace only parts of a line. The font index in the rendition will |
|
|
621 | automatically be updated. |
|
|
622 | |
|
|
623 | C<$text> is in a special encoding: tabs and wide characters that use more |
|
|
624 | than one cell when displayed are padded with urxvt::NOCHAR characters |
|
|
625 | (C<chr 65535>). Characters with combining characters and other characters |
|
|
626 | that do not fit into the normal tetx encoding will be replaced with |
|
|
627 | characters in the private use area. |
|
|
628 | |
|
|
629 | You have to obey this encoding when changing text. The advantage is |
|
|
630 | that C<substr> and similar functions work on screen cells and not on |
|
|
631 | characters. |
|
|
632 | |
|
|
633 | The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
|
|
634 | can be used to convert normal strings into this encoding and vice versa. |

636 | =item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
637 | |
|
|
638 | Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
|
|
639 | bitsets. Rendition bitsets contain information about colour, font, font |
|
|
640 | styles and similar information. See also C<< $term->ROW_t >>. |
|
|
641 | |
|
|
642 | When setting rendition, the font mask will be ignored. |

|
|
646 | =item $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
647 | |
|
|
648 | Returns the number of screen cells that are in use ("the line |
|
|
649 | length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the |
|
|
650 | line is joined with the following one. |
|
|
651 | |
|
|
652 | =item $bool = $term->is_longer ($row_number) |
|
|
653 | |
|
|
654 | Returns true if the row is part of a multiple-row logical "line" (i.e. |
|
|
655 | joined with the following row), which means all characters are in use |
|
|
656 | and it is continued on the next row (and possibly a continuation of the |

657 | previous row(s)). |
|
|
658 | |
|

|
|
661 | Create and return a new C<urxvt::line> object that stores information |
