«Shows you how to implement a custom dialog in Frontier
«This script allows you to change the type and creator of any file
«It's also a sample for doing custom dialogs in Frontier
«
«The dialog it's running is in the Dialogs folder
«In the same folder as the Frontier application
«If you write your own custom dialog you should...
«Design the dialog using a resource editor.
«Make sure that the DLOG resource id is 25000.
«Same for the DITL resource.
«Take note of the item numbers, they're used in the script.
«In dialog.getValue and dialog.setValue calls.
«How the script works:
«It prompts for a file of any type (that's what the 0 is for).
«...in the file.getFileDialog call
«Then it calls dialog.runFromFile, which repeatedly calls itemHit.
«itemHit is prepared for 3 kinds of "hits":
«a signal from Frontier to initialize the dialog
«this will come just as the dialog is opening
«it allows you to set the initial values of the fields
«a click on the OK button
«we save off the values entered in the dialog
«and send a signal back to Frontier to close the dialog
«a click on the Cancel button
«we send a signal back to Frontier to close the dialog
«
«Hope this helps!
