X11::Protocol::Ext::MIT_SUNDRY_NONSTANDARD(3)

NAME
X11::Protocol::Ext::MIT_SUNDRY_NONSTANDARD - X11R2/R3 compatibility mode

SYNOPSIS
 use X11::Protocol;
 my $X = X11::Protocol->new;
 $X->init_extension('MIT-SUNDRY-NONSTANDARD')
   or print "MIT-SUNDRY-NONSTANDARD extension not available";

DESCRIPTION
The MIT-SUNDRY-NONSTANDARD extension controls a "bug mode" setting in the server which helps some X11R2 and X11R3 client programs, including "xterm" from those releases.

Bug mode means: relaxing event mask checking in grab pointer and button requests and window do-not-propagate attributes (to ignore mask bits which are not applicable); something for non-overlapping sibling window stacking order; and keeping maximum keycode below 255 to avoid an Xt toolkit segfault. Unless working with old client programs then these things are unlikely to be of interest.

REQUESTS
The following are made available with an init_extension() per "EXTENSIONS" in X11::Protocol.

    my $bool = $X->init_extension('MIT-SUNDRY-NONSTANDARD');

"$X->MitSundryNonstandardSetBugMode ($flag)"
"$flag = $X->MitSundryNonstandardGetBugMode ()"
    Get or set the bug mode flag. 1 means compatibility mode is on, 0 means off.

SEE ALSO
X11::Protocol

xset(1) "bc" option to control the bug flag from the command line.

Xserver(1) "bc" command-line option to set the flag at server startup.
