file types with drag/drop

Scripting Forums AppleScript Studio & Xcode
#1

hey guys, im new here, and pretty new to applescripting in general. And while i have learned quite a lot in the past few days, mostly from google results on this site, so I thought Id ask this problem here for which I could not find an answer.

I have need to know the type of file being dropped in an on drop handler for reasons being, i need to not accept dropped folders when afolder is dropped in one place, and only accept jpg and pngs when they are dropped in another place. How can I tell what the of of the file is when it has been dropped?

Help is much appreciated. thanks in advance.

The simplest way is to use the info for command. Here is one way that may get you started:


on open the_Droppings
	set OK_Files to {}
	set dropped_Folders to {}
	repeat with a_Drop in the_Droppings
		if folder of (info for a_Drop) then
			set end of dropped_Folders to a_Drop
		else
			if name extension of (info for a_Drop) is "jpg" or name extension of (info for a_Drop) is "png" then
				set end of OK_Files to a_Drop
			end if
		end if
	end repeat
	display dialog "You dropped " & (OK_Files's length) & " JPG or PNG files, and " & (dropped_Folders's length) & " folders just now."
end open

I dont know if I wasnt completely clear or not, but im not working with a droplet, just drop action in an applescript application. would the code below based on the info for do the trick?


on drop theObject drag info dragInfo
set dataTypes to types of pasteboard of dragInfo

set theFiles to {}
set theFiles to contents of pasteboard of dragInfo

repeat with thisFile in theFiles
   if folder of (info for thisFile) then
     display dialog "This is a Folder"
   else if name extension of (info for thisFile) is "jpg" or name extension of (info for thisFile) is "png" then
     display dialog "this is a valid image"
   end if
     
end repeat
end drop

aparrantly not. the script cant find “thisFile” (of course the actual path is displayed, but it is the thisFile that cant be found)

Umm. Yes, I see. Sorry about that; I’ve no experience with that sort of thing. Have you studied the Drag and Drop example in your Developer/Examples/AppleScript Studio folder? Perhaps there are some clues there.

Thanks for the help jaques, Ill add in the code later today and let you know how it goes. Im sure it will work though. I had tried to set the file as posix already, but I was using “POSIX path of” instead of “POSIX file”
