Now that you have created the application and tested its scriptability, let s see whether you can put it to use. Your strategy will be to start by telling the application to show the window you want to use as a dialog box. Then, you will wait until the window isn t showing anymore, and finally, when that happens, you will extract the values from the different controls.

The part of the script that shows the dialog box will look like this: tell application "dialogs" activate tell window "user info" repeat with name_ref in {"chosen button", "name", "phone", "email"} set contents of text field name_ref to "" end repeat set visible to true --more to come here end tell end tell You start by activating the application. This brings the application to the front so users will be able to enter data into its dialog box window. Then, you clear the text from all the editable text fields. This is important since you don t want the dialog box to retain the values from the last time you used it. Instead of clearing the text fields, you could use this part to populate them with default values as well. Then you set the value of the window object s visible property to true, which simply makes the window visible onscreen.

Next, you will create a repeat loop that will go on as long as the window is visible. Since you want to replicate the script s natural behavior, the script has to sit there until the user clicks a button. The script with the waiting repeat loop looks like this: tell application "dialogs" activate tell window "user info" set contents of every text field to "" set visible to true --Wait for window to close: repeat while visible delay 0.1 end repeat --more to come here end tell end tell

The script could, if you needed to, track the time the dialog box is open and close it after a while. This would make the dialog box behave like Standard Additions display dialog command does when you use its giving up after parameter. For example, to make the dialog box automatically dismiss itself after ten seconds, you would use the following waiting loop: set seconds_passed to 0 repeat while visible and seconds_passed < 10 delay 0.1 set seconds_passed to seconds_passed + 0.1 end repeat The external script can then check to see whether the chosen button text field contains an empty string; if it does, it means the dialog box must have expired by itself.
