Is there a way to disable the keyboard in macos x?

I am looking for a way I can use this functinality in an application. So preferably something that can be done programatically and does not need root previlages?

I want the keyboard to be dsabled everywhere in the os, even if the application is in the background, until I enable it by pushing a butten for example.

I am new to mac os programming so will appreciate more elaborations :)

UPDATE: I am trying to use this: CGEventTapCreate but cannot get it to work. Anyone nows how to make it work in swift 3?

You can override the keyDown and keyUp events and leave the function without calling its super class

override func keyDown(with event: NSEvent) {
    //super.keyDown(event)
}
override func keyUp(with event: NSEvent) {
    //super.keyUp(event)
}

The above code works for NSTextView

For NSTextField, you should manually delete the letter entered. As for NSTextfield's keyDown event will not be called when overrided. 

override func keyUp(with event: NSEvent) {
    self.stringValue = ""
}

I used these techniques, but not really sure if this is right way to do... But it works :P

  • Thank for the responce, but let make myself clear. I want to completely disabe the keyboard, any input, anywhere, not just in the app. – armin Nov 20 '18 at 18:42
  • This would not work. I want to disable/enable keyboard based on clickong a button. Thanks though. – armin Nov 25 '18 at 18:54
