Does anybody know a simple method of closing a created window from within the main.js that created it. I ask this as although I have resolved this with a convoluted method, it is not ideal. When created, the window.create() does return a PID but it seems that is not a system PID but one that is created by Neutralino. The only way this can be done as far as I am aware is to do a search for the system PID based on the window title and then do a taskKill on that. I would have thought there should be a way to do this using the Neutralino PID. Any help would be appreciated.
