if statement asking if an addlistener() event has occured

1 次查看(过去 30 天)
Is there a way to write an if statement that says something like:
if % addlistener(handles.Edit1, 'String','PostGet',f) occured %do something end

I don't really understand why you would want to do this. The purpose of the listener is to fire when something (some event) happens. Why then do you need an if()? When this something happens, the listener will fire and your if() will happen automagically.

Your handles must have been associated with a different figure number I guess.

or improperly GUIDATAed (new verb!). That is why I avoid GUIDATA like the plague.

Have the listener set a variable in an area you can test.

So could I use an expression such as
addlistener(handles.Edit1, 'String', 'PostGet', n=1);
then test my n variable? I tried it and it doesn't like the expression at all and I can't find any documentation why.
