I am keeping track of all Finder windows opened by using a
an applet and within the idle cycle, I run:
tell application "Finder"
set windowList to every Finder window
set windewListAsText to ""
repeat with thisWindow in windowList
try
set thePath to thisWindow's target as string
set theSize to (size of (folder thePath)) / (1024 ^ 2) as integer
-- set newSize to theSize / (1024 ^ 2) as integer
on error
set theSize to "0"
end try
try
set windewListAsText to windewListAsText & thisWindow's id & tab & thisWindow's index & tab & thisWindow's name & tab & thisWindow's target & tab & ((theSize as string) & " MB") & linefeed
on error
set windewListAsText to windewListAsText & thisWindow's id & tab & thisWindow's index & tab & thisWindow's name & tab & "No path found" & tab & "0 MB" & linefeed
end try
end repeat
return windewListAsText
end tell
Is there any way to skip the cycle if the “Finder” has NOT changed.
I mean: I wonder if there is any property that I can interrogate to check whether it is worth to run the code above:
Something like:
If FinderHasChanged then
--> run the above code
else
return -- skipping idle
end if
I hope I understood you correctly. It is not possible to skip the execution of the on idle() handler, so you would probably want to skip some actions in this handler (do nothing).
I’m not sure, but I don’t think the Finder updates the folder’s size immediately, so the script might not work properly. In any case, I would start like this:
property windowsInfo : ""
on run {}
set windowsInfo to my getFinderWindowsInfo()
end run
on idle
set newWindowsInfo to my getFinderWindowsInfo()
if newWindowsInfo = windowsInfo then
-- do nothing
else
-- do something. For example:
tell me to activate
tell me to display dialog "Some of the Finder window still is updated" giving up after 1
set windowsInfo to newWindowsInfo
end if
return 1
end idle
on getFinderWindowsInfo()
tell application "Finder"
set windowList to Finder windows
if windowList is not {} then reopen it
set windewListAsText to ""
repeat with thisWindow in windowList
try
set theSize to (size of (thisWindow's target)) / (1024 ^ 2) as integer
on error
set theSize to "0"
end try
try
set windewListAsText to windewListAsText & thisWindow's id & tab & thisWindow's index & tab & thisWindow's name & tab & thisWindow's target & tab & ((theSize as string) & " MB") & linefeed
on error
set windewListAsText to windewListAsText & thisWindow's id & tab & thisWindow's index & tab & thisWindow's name & tab & "No path found" & tab & "0 MB" & linefeed
end try
end repeat
return windewListAsText
end tell
end getFinderWindowsInfo
. NOTE: The script in this form will not notice changes if the folder size is changed by < 1 MB. To notice the slightest changes, do not convert Bytes to MB.
You can also use the PFAssistive framework from the PFiddlesoft website (https://pfiddlesoft.com/frameworks/index.html) and register an observer.
Unfortunately, the website is only available until October 17.
use AppleScript version "2.4" -- Yosemite (10.10) or later
use scripting additions
use framework "Foundation"
use framework "AppKit"
use framework "PFAssistive"
set observer to current application's PFObserver's observerWithBundleIdentifier:"com.apple.finder"
observer's setDelegate:me
observer's registerForNotification:(current application's NSAccessibilityMainWindowChangedNotification) fromElement:(missing value) contextInfo:(missing value)
on applicationWithIdentifier:theIdentifier atPath:theFullPath didPostAccessibilityNotification:theNotification fromObservedUIElement:theObservedUIElement forAffectedUIElement:theAffectedUIElement
display notification (theAffectedUIElement's AXTitle as text)
end applicationWithIdentifier:atPath:didPostAccessibilityNotification:fromObservedUIElement:forAffectedUIElement:
-- delay 60 -- for testing in the Script Editor
Note: The observer is only active as long as the script is running. Therefore the delay at the end of the script for testing in the Script Editor. For the runtime it’s better to use a Stay-Open Applet.
Many thanks to Bill Cheeseman for his great work - Especially the UI Browser!
