.SH NAME
|

|
|
after \- Execute a command after a time delay
|
||
|
|
.SH SYNOPSIS
|
||
|
|
\fBafter \fIms \fR?\fIarg1 arg2 arg3 ...\fR?
|
||
|
|
.BE
|
||
|
|
|
||
|
|
.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
This command is used to delay execution of the program or to execute
|
||
|
|
a command in background after a delay. The \fIms\fR argument gives
|
||
|
|
a time in milliseconds.
|
||
|
|
If \fIms\fR is the only argument to \fBafter\fR
|
||
|
|
then the command sleeps for \fIms\fR milliseconds and returns.
|
||
|
|
.VS
|
||
|
|
While the command is sleeping the application does not respond to
|
||
|
|
X events and other events.
|
||
|
|
.VE
|
||
|
|
.PP
|
||
|
|
If additional arguments are
|
||
|
|
present after \fIms\fR, then a Tcl command is formed by concatenating
|
||
|
|
all the additional arguments in the same fashion as the \fBconcat\fR
|
||
|
|
command. \fBAfter\fR returns immediately but arranges for the command
|
||
|
|
to be executed \fIms\fR milliseconds later in background.
|
||
|
|
.VS
|
||
|
|
The command will be executed at global level (outside the context
|
||
|
|
of any Tcl procedure).
|
||
|
|
.VE
|
||
|
|
If an error occurs while executing the delayed command then the
|
||
|
|
\fBtkerror\fR mechanism is used to report the error.
|
||
|
|
.PP
|
||
|
|
The \fBafter\fR command always returns an empty string.
