Listing all windows of all applications - macos

Question

I am trying to write an applescript script that resizes all open windows. In order to make sure that I'm getting to all the windows, I'm making my script say the name of the application as well as the number of open windows of that application.
Interestingly, while I hear the names of all my open applications, my script says that they all have 0 windows open. How can I fix this issue?
Here's my code:
tell application "System Events"
repeat with theProcess in (every process)
if background only of theProcess is false then
if name of theProcess is not "Finder" then
if name of theProcess is "Google Chrome" then
say "Chrome woo hoo"
say (count windows as string)
else
say name of theProcess as string
say (count windows as string)
tell theProcess
repeat with theWindow in windows
say "found a window of"
say (name of theProcess) as string
tell theWindow
click button 2
end tell
end repeat
end tell
end if
end if
end if
end repeat
end tell
I'm on Mac OS X 10.7.5, using automator 2.2.4 to write/run this applescript

You have to tell the process to count windows. After all it's the process that knows about its windows, not system events.
You have told the process to say its name e.g. "say name of theProcess as string" however you only use "say (count windows as string)"... no process is tied to that. Try "count windows of theProcess". Basically you have lines where sometimes you tell the process, other times you don't, and other times where you tell the process even though you've already told the process, so you do it twice. That's where you have "say (name of theProcess) as string" but that code is inside a "tell theProcess" block so it's already being told to theProcess.
Really you need to go through your code and be more precise. A tip... if you want to click a button in a window then the window must be frontmost on the screen otherwise you can't click it. Another tip... "name" is already a string so you don't need to coerce that to a string.
By the way, I agree with Michael Dautermann's comment to your post... there will be processes where you won't get access. But you'll find that out as you progress.
Here's how I would write your code. Basically I would get all of the variables at the beginning using a "tell theProcess" block. Then I can do stuff with those variables. I hope that helps. Notice that I only made the process frontmost which means if it has multiple windows open it will only click a button on the front window. You'll have to add code to make each window come to the front before you can click its button. Good luck.
tell application "System Events"
repeat with theProcess in processes
if not background only of theProcess then
tell theProcess
set processName to name
set theWindows to windows
end tell
set windowsCount to count of theWindows
if processName is "Google Chrome" then
say "Chrome woo hoo"
say windowsCount as text
else if processName is not "Finder" then
say processName
say windowsCount as text
if windowsCount is greater than 0 then
repeat with theWindow in theWindows
say "found a window of " & processName
tell theProcess
set frontmost to true
tell theWindow
click button 2
end tell
end tell
end repeat
end if
end if
end if
end repeat
end tell

I create a list of all open windows of visible applications on Mavericks like this:
tell application "System Events"
set this_info to {}
repeat with theProcess in (application processes where visible is true)
set this_info to this_info & (value of (first attribute whose name is "AXWindows") of theProcess)
end repeat
this_info -- display list in results window of AppleScript Editor
end tell
You need to allow any app using this to access the interface under Accessibility.
