.SH NAME
minput_set_spot - Set the spot of the input context. 


.SH SYNOPSIS
void
\fBminput_set_spot\fP (\fBMInputContext\fP *
\fIic\fP, int
\fIx\fP, int
\fIy\fP, int
\fIascent\fP, int
\fIdescent\fP, int
\fIfontsize\fP, \fBMText\fP *
\fImt\fP, int
\fIpos\fP)


.SH DESCRIPTION
The
.ft B
minput_set_spot()
.ft R
function sets the spot of input context
.ft B
ic
.ft R
to coordinate (\fBx\fP,
.ft R
.ft B
y
.ft R
) with the height specified by
.ft B
ascent
.ft R
and
.ft B
descent\fP.
.ft R
The semantics of these values depends on the input method driver.
.PP
For instance, a driver designed to work in a CUI environment may use
.ft B
x
.ft R
and
.ft B
y
.ft R
as the column- and row numbers, and may ignore
.ft B
ascent
.ft R
and
.ft B
descent\fP.
.ft R
A driver designed to work in a window system may interpret
.ft B
x
.ft R
and
.ft B
y
.ft R
as the pixel offsets relative to the origin of the client window, and may interpret
.ft B
ascent
.ft R
and
.ft B
descent
.ft R
as the ascent- and descent pixels of the line at (\fBx\fP.
.ft R
.ft B
y
.ft R
).
.PP
.SS fontsiz specifies the fontsize of preedit text in 1/10 point.
.PP
.SS mt
.ft R
and
.ft B
pos
.ft R
are the M-text and the character position at the spot.
.ft B
mt
.ft R
may be
.ft C
NUL, in which case, the input method cannot get information about the text around the spot.
