<li>fix redrawing of windows other than <code>stdscr</code> using - <code>wredrawln()</code> by touching the corresponding rows in - <code>curscr</code>. + <li>improve refresh of window on top of multi-column characters, + taking into account split characters on left/right window + boundaries. - <li>reduce memory leaks in repeated calls to <code>tgetent()</code> by - remembering the last <code>TERMINAL*</code> value allocated to hold - the corresponding data and freeing that if the - <code>tgetent()</code> result buffer is the same as the previous - call. + <li>modify <code>win_wchnstr()</code> to ensure that only a base cell + is returned for each multi-column character. - <li>modify <code>read_termtype()</code> so the <code>term_names</code> - data is always allocated as part of the <code>str_table</code>, a - better fix for a memory leak. + <li>improve <code>waddch()</code> and <code>winsch()</code> handling of + EILSEQ from <code>mbrtowc()</code> by using <code>unctrl()</code> + to display illegal bytes rather than trying to append further bytes + to make up a valid sequence. - <li>fix <code>wins_nwstr(),</code> which did not handle single-column - non-8bit codes. + <li>restore <code>curs_set()</code> state after + <code>endwin()</code>/<code>refresh()</code> - <li>modify <code>wbkgrnd()</code> to avoid clearing the - <code>A_CHARTEXT</code> attribute bits since those record the state - of multicolumn characters. + <li>modify <code>keyname()</code> to use "^X" form only if + <code>meta()</code> has been called, or if <code>keyname()</code> + is called without initializing curses, e.g., via + <code>initscr()</code> or <code>newterm()</code>. - <li>improve <code>SIGWINCH</code> handling by postponing its effect - during <code>newterm()</code>, etc., when allocating screens. + <li>modify <code>unctrl()</code> to check codes in 128-255 range versus + <code>isprint()</code>. + If they are not printable, and locale was set, use a "M-" or "~" + sequence. - <li>remove 970913 feature for copying subwindows as they are moved in - <code>mvwin()</code>. + <li>improve <code>resizeterm()</code> by moving ripped-off lines, and + repainting the soft-keys. - <li>add checks in <code>waddchnstr()</code> and - <code>wadd_wchnstr()</code> to stop copying when a null character - is found. + <li>modify form library to accept control characters such as newline + in set_field_buffer(), which is compatible with Solaris. - <li>add some checks to ensure current position is within scrolling - region before scrolling on a new line. + <li>use <code>NCURSES_MOUSE_MASK()</code> in definition of + <code>BUTTON_RELEASE()</code>, etc., to make those work properly + with the <code>--enable-ext-mouse</code> configuration -
