Syntax:>
dialog = expr%
Description:
This statement posts a dialog
event of type _userDialog
to FutureBasic's internal dialog
queue. This allows your program to post "custom events" to itself. After you post a _userDialog
event, you can use the dialog
function to subsequently read the event from the queue (normally you'll do this from within the dialog-event handling function designated by an on dialog
statement). If you retrieve the event from the queue as follows:
evnt = dialog(0)
id = dialog(evnt)
then evnt
will be set to the value _userDialog
(which equals 23), and id
will be set to the value of expr%
that you specified in the dialog
statement.
To learn how to pass additional information associated with an event of type _userDialog
, see the descriptions of the event%
and event&
statements, and the event%
and event&
functions.
