如何在 Mac AppleScript 中从 PID 获取要调用的应用程序名称

Question

There is a script that lets you resize any app in mac. This is the code:

set theApp to "Application Name" 
set appHeight to 1080
set appWidth to 1920

    tell application "Finder"
    set screenResolution to bounds of window of desktop
end tell

set screenWidth to item 3 of screenResolution
set screenHeight to item 4 of screenResolution

tell application theApp
      activate
      reopen
      set yAxis to (screenHeight - appHeight) / 2 as integer
      set xAxis to (screenWidth - appWidth) / 2 as integer
      set the bounds of the first window to {xAxis, yAxis, appWidth + xAxis, appHeight + yAxis}
      end tell

I want to change the size of a java application opened by a launcher. When I insert the name of any app, it works. However when I insert the name of the app that I want to resize it doesn't work. I know the process id of the app that I want to resize. Is there a way I can change this line set theApp to "Application Name" to use PID instead of Application name? Thanks.

Not all apps are AppleScript scriptable and some that are do not support the bounds property , they use position property and size property . Also, sometimes you'll need System Events to position and size an app's window .

I use a keyboard shortcut assigned in FastScripts with the following example AppleScript code to automatically adjust the frontmost app's window . You can adjust the code to suite your needs.

If the frontmost app can't use the bounds property it silently errors , and then System Events does it.

tell application "System Events"
    set frontmostProcess to name of process 1 whose frontmost is true
end tell

try
    tell application frontmostProcess
        set bounds of window 1 to {0, 22, 1136, 844}
    end tell
on error
    tell application "System Events" to tell application process frontmostProcess
        set position of window 1 to {0, 22}
        set size of window 1 to {1136, 822}
    end tell
end try
