Learning to script OmniGraffle
 

Where does one go to learn how to script OG? Reading the scripting dictionary only takes you so far.

My immediate problem: how to get/set the text in an existing text object.
So far, I haven't been able to figure out how to refer to the text object. In an existing drawing, how do I figure this out?

tell application "OmniGraffle Professional 4"
tell document "My Doc"
tell layer 1 of canvas 1
what goes in here?
end tell
end tell
end tell

You can get a head start on how OmniGraffle objects are handled via AppleScript by creating an object, and then copying it as AppleScript from the Edit Menu --> Copy As submenu.

Hope that helps,

OK, I'm making progress, but now I need to know how to make OmniGraffle Pro 4 print. There's only one document open.
tell application "OmniGraffle Professional 4" to print front document without print dialog
just gives an error message: "document 1 doesn't understand the print message"
"print document 1" gives the same message.
