Instead, the xterm mouse + report sequence will appear in the string read. + + Mouse events under xterm will not be detected correctly in a window + with its keypad bit off, since they are interpreted as a variety of + function key. Your terminfo description should have <STRONG>kmous</STRONG> set to + "\E[M" (the beginning of the response from xterm for mouse clicks). + Other values for <STRONG>kmous</STRONG> are permitted, but under the same assumption, + i.e., it is the beginning of the response. + + Because there are no standard terminal responses that would serve to + identify terminals which support the xterm mouse protocol, <STRONG>ncurses</STRONG> as- + sumes that if <STRONG>kmous</STRONG> is defined in the terminal description, or if the + terminal description's primary name or aliases contain the string + "xterm", then the terminal may send mouse events. The <STRONG>kmous</STRONG> capability + is checked first, allowing the use of newer xterm mouse protocols such + as xterm's private mode 1006. + + +</PRE><H2><a name="h2-SEE-ALSO">SEE ALSO</a></H2><PRE> + <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="curs_kernel.3x.html">curs_kernel(3x)</A></STRONG>, <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG>, <STRONG><A HREF="curs_variables.3x.html">curs_variables(3x)</A></STRONG>. - <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> + <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> </PRE> -<HR> -<ADDRESS> -Man(1) output converted with -<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a> -</ADDRESS> +<div class="nav"> +<ul> +<li><a href="#h2-NAME">NAME</a></li> +<li><a href="#h2-SYNOPSIS">SYNOPSIS</a></li> +<li><a href="#h2-DESCRIPTION">DESCRIPTION</a> +<ul> +<li><a href="#h3-mousemask">mousemask</a></li> +<li><a href="#h3-Mouse-events">Mouse events</a></li> +<li><a href="#h3-getmouse">getmouse</a></li> +<li><a href="#h3-ungetmouse">ungetmouse</a></li> +<li><a href="#h3-wenclose">wenclose</a></li> +<li><a href="#h3-wmouse_trafo">wmouse_trafo</a></li> +<li><a href="#h3-mouse_trafo">mouse_trafo</a></li> +<li><a href="#h3-mouseinterval">mouseinterval</a></li> +<li><a href="#h3-has_mouse">has_mouse</a></li> +</ul> +</li> +<li><a href="#h2-RETURN-VALUE">RETURN VALUE</a></li> +<li><a href="#h2-PORTABILITY">PORTABILITY</a></li> +<li><a href="#h2-BUGS">BUGS</a></li> +<li><a href="#h2-SEE-ALSO">SEE ALSO</a></li> +</ul> +</div> </BODY> </HTML> |
