Illustrator CS5 Checkbox problem

Scripting Forums AppleScriptObjC and Xcode
#1

Hi

Please can someone help. Why do I get an error using the script below?

The app runs OK until I uncheck (or re-check) the check box in the UI i have.


script AppDelegate
	property parent : class "NSObject"
    property window : missing value
    
	property Thischeckbox : true
    
	    on buttonClicked_(sender)

             tell application "Adobe Illustrator"
                activate
                tell document 1
                    display dialog "The check box returned = " &  Thischeckbox
                 end
            end
        end
    
	
	on applicationWillFinishLaunching_(aNotification)
		-- Insert code here to initialize your application before any files are opened 
	end applicationWillFinishLaunching_
	
	on applicationShouldTerminate_(sender)
		-- Insert code here to do any housekeeping before your application quits 
		return current application's NSTerminateNow
	end applicationShouldTerminate_
	
end script

Also, I do not get an error if I move the dialog to before the document tell block. Something about Illustrator seems to be loosing the boolean value of the checkbox.

Thanks for any help.

I’m running Xcode 5.1 on Mavericks.

I don’t know if this matters, but at least from a readability standpoint, I would rewrite your buttonClicked method like this:


on buttonClicked_(sender)
	
	tell application "Adobe Illustrator"
		activate
		tell document 1
			display dialog "The check box returned = " & Thischeckbox
		end tell
	end tell
	
end buttonClicked_

A checkbox is a button, and its state is not a boolean yes/no, but an integer 0/1/-1, where -1 is mixed state (if you allow it). Normally you can get away with using booleans, but sometimes it causes problems.

So when the state of the button is set by the UI, it is no longer an AS true/false, but rather an NSNumber. To display that value in an AppleScript dialog, you have to coerce it AppleScript as an integer (or boolean). So try this:

           display dialog "The check box returned = " & (Thischeckbox as integer)

Thanks Shane but…

Still no luck. Tried your solution but the dialog still does not like it.

I get the error: “Can’t make «class ocid» id «data optr0000000000F8577DFF7F0000» into type integer. (error -1700)”

I’ve managed to get around the problem however by passing off the result to a another variable before the error occurs but would still be interested in a solution.

Thanks

Thanks X74353

You are dead right. The readability of the code does matter. Thanks.

You probably need to coerce the NSNumber to an integer outside the Illustrator tell block.

Thanks Shane.

Can’t try it right now but would this work?

property Thischeckbox : true as integer

?

No. You need something like:

on buttonClicked_(sender)
   set theResponse to Thischeckbox as integer
   tell application "Adobe Illustrator"
       activate
       tell document 1
           display dialog "The check box returned = " & theResponse
       end tell
   end tell
   
end buttonClicked_
