- .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.
