SYNOPSIS
Get_XInfo(out string display,
out string visual,
out integer depth
[in messageID commission]);
DESCRIPTION
The Get_XInfo request reports the X11 attributes of the optionally
specified window, or of the window primarily associated with the recip‐
ient procid (if no window is specified).
The display argument is an X11 display.
The visual argument is an X11 visual class (which determines how a
pixel will be displayed as a color). Valid values are:
StaticGray
GrayScale
StaticColor
PseudoColor
TrueColor
DirectColor
The depth argument is the number of bits in a pixel.
The commission argument is the ID of the ongoing request with respect
to which X11 attributes are being set or reported.
APPLICATION USAGE
The ttdt_session_join(3), and ttdt_message_accept(3), functions can be
used by Xt applications to register for, and transparently process, the
Get_XInfo request. Also, Get_XInfo can be sent by
ttdt_sender_imprint_on(3).
Since the handler may be running on a different host, it is almost
always better to return a display value of hostname:n[.n] instead of
:n[.n].)
The commission argument is useful to the extent that the handler
employs different attributes for the different operations it may be
carrying out.
EXAMPLES
The Get_XInfo request can be sent as in the following example:
Tt_message msg = tttk_message_create(0, TT_REQUEST, TT_SESSION,
the_recipient_procid, TTDT_GET_XINFO,
my_callback);
tt_message_arg_add(msg, TT_OUT, Tttk_string, 0);
tt_message_arg_add(msg, TT_OUT, Tttk_string, 0);
tt_message_iarg_add(msg, TT_OUT, Tttk_integer, 0);
tt_message_send(msg);
