I have an app with an AppTextEdit item. I want to type text with accented characters (é, à, etc). On MacOS you do this by holding down the key and then a pop up window shows, like this: http://osxdaily.com/2017/03/22/type-accents-mac-easy/. However, in my app when I hold down the key, it prints the character repeatedly. I also notice that if I turn off key repeats in the OS system preferences, this has no effect in my app. I understand this behaviour is useful for games where key repeats are needed, but is there any workaround for apps?
