Send KeyEvent to a Target window via process Id

Question

I need to create a key event (cmd + r for refresh for the browser window) and pass the process Id for the window I\'m trying to target. Let\'s say

    let custo         


        

Answer 1

In your case all you need to do is to call postToPid on your CGEvent instance, and pass the PID as argument:

let cgEvent = customEvent!.cgEvent
cgEvent?.postToPid(168) 

Edit
Your code doesn't work because you're just sending a key up event, not CMD+R. You can do this easily in AppleScript. See this question: Mac: reloading document in Chrome or Firefox?

Edit 2

Without AppleScript, this is how I would do it:

let src = CGEventSource(stateID: .hidSystemState)
if let event = CGEvent(keyboardEventSource: src, virtualKey: 0x0f, keyDown: true)
{
    event.flags = .maskCommand
    event.postToPid(your_browser_pid)
}
