Stephen,
Modal dialog windows prevent scripts that are not in the modal
stack from continuing to execute. That is why I usually put a
function like yours into the modal stack itself. The function
may open the stack and wait with messages until there is no
window <short name of the modal stack>, before returning the
dialogdata.
Most of the time, I don't use a function for that. I send a
message to the dialog window to open itself. The script from
where I send that message will halt until the window has
disappeared. In the OK button, I include a separate script to
set the dialogData. In this way, you don't need to wait with
messages. Once the dialog has closed, the script from where the
message to open it was sent, will continue and can read out the
dialogData.
Best regards,
Mark

I'm currently recreating in REV what I used to use a Rinaldi XCMD for...
namely a listbox dialog for choosing items from a list.
The idea is to have a function
function listbox pPromptData,pListData
that puts up a window with a prompt field, and a list field. Select and
click an item or hit return or enter. Standard GUI stuff.
This would return the selected item or empty.
I've created the new window/stack, I'm using dialogData to pass the info
back and forth, and I have the function that sets up the data and opens
the window. I had figured on using wait with messages to halt script
execution until the dialog was closed, but I can't seem to send the
right message to it from the dialog closing to get it to go to the next
line of code, 'BEEP'. I also tried changing a variable. Anyone found the
best way to deal with this?
Eventually I'd like to be able do it all from a script on the fly -
create the window,fields, buttons, everything, from a text description
before display like I used to do in WindowScript... it's all about
properties, after all....
thanks...
--this is located in the stack script of the calling stack
--scrunch converts returns to VTs to get more data in dialogdata
function dialogList pPrompt,pListData
global gDialogFlag
if there is a stack "listDialog"
then
put scrunch(pPrompt) & return & scrunch(pListData) into tDialogTxt
set the dialogData to tDialogTxt
--- put the dialogData
-- exit to top
put "true" into gDialogFlag
open stack "listDialog" <------ this is the dialog
wait with messages
-- wait until gDialogFlag is "false" with messages??
beep <--------this never executes
else
answer "Can't find stack: listDialog"
exit to top
end if
return the dialogData
end dialogList
