statement

Syntax:
window output idExpr
Description:
This statement makes an existing window the current output window. The
current output window is the destination for any subsequent text and
drawing commands, and is the target window for such statements and
functions as button
, edit field
,
etc.
The idExpr
can be either a
positive or negative number; window output
affects the window whose ID number is abs(idExpr)
.
If you specify a negative idExpr
,
the window becomes invisible. If you specify a positive idExpr
,
the window becomes visible.
window output
does not
activate the specified window (i.e., it does not highlight its contents
nor bring it to the front), if there are other visible windows open.
Use the window
statement ( or Appearance Window statement )
when you want to explicitly activate a window. (Note: the window
statement also makes the specified window the current
output window.)
window output
is useful in
cases where you need to update the contents of a window which may be in
the background, without bringing the window to the front.
