Not at all. I have a File Server Agent that uses socket communications. I first
get a list of files from the user, then I query the server or a list of what I
call Profiles which right now are just a name and a file path on the server.
I want to present the client user with a list of the names of those profiles.
If the user does not select a profile, either by clicking off the menu I pop
up, or by hitting the escape key, then I notify the user that they must choose
a profile.
If they do choose a profile then I send the server an array with some
key/values, and the file data is stored in a numbered array in the data key.
Each key in the data keys is first encrypted, then tho whole of the array is
arrayEncoded, then base 64Encoded before opening a socket and sending the data.
I tried using the popup menu button but that will not work unless the popup
button command is called from a mouseDown or mouseUp handler. I am making the
call from a behavior script which is why I was getting the error. And besides,
you can’t control the popup menu’s appearance, whereas with a field you can.
Also I am anticipating having more values than can be entirely displayed by a
popup menu without running out of screen real estate, so a scrolling field
works much better.
I’m curious how you would do that with native controls?
