Menu Buttons

[dunbarx at aol.com]

When you say you want to drive the menuItems displayed by script, does that mean you never want to use the mouse at all? I made a workaround recently where I did something like this, and I am giving you a snippet for your examination. Make two buttons, one an ordinary one, and one a combo box. Put several choices into the combo. Place the comboBox so that the loc of its selection arrow is, say, "200,200". In the regular button script write:


on mouseUp
   click at "200,200"
   wait 50
   click at "175," && 225 + random(100)
end mouseUp


This should open the combo box and select a random line within it. You can trap a "menuPick" message inside the combo box. Not sure what you are doing, but this might give you a hint as to a possible method. HTH.

Subject: Menu Buttons


I am trying to create a series of "helps" where I step a user through a process 
using the underlying tool. I have one "help" field that variously shows, hides, 
fills, and moves around.

The scripts "say" things (aural feedback).

There is a "pointer" button that locates as needed, flashes, and shows/hides.

Here's my problem. Suppose I have a menu button that affords several choices. In 
my application, I can click the button, move among the choices from a list that 
is displayed -- with a choice automatically hiliting as I move around (hovering) 
in the list, and then click to make the hilited choice. 

I want to drive that from a script. Is there an easy way? The list seems to 
behave like some sort of modal stack that I must deal with. That is, if I create 
a script that pops out the list, that list behaves as I would expect -- FROM 
MOUSE ACTIONS -- but I haven't found scripting that leads to the same effects. I 
suppose I could capture images and use these AS IF they were the real thing, but 
then I'd have less flexibility than if I did this from scripts. 

Should I simply redesign things such that buttons display fields and try to go 
from there? I seem to be able to get that approach to work from scripts, but it 
seems cumbersome.

Thanks in advance for your help.
