I've created a simple text editor that autosaves txt files every minute and also spell checks the TextArea with the languagetool java api. I'd like to have the autosaving done when the user stops typing and also have the spellchecking done when the user stops typing as well. I think I can do it some way with the OnKeyPressed and OnKeyRealesed methods associated with the textarea and use System.currentTimeMillis method but I have not been able to figure that out. I also thought it’d be best to do these processes in another thread but I was unsure how to implement that.
The auto saving and spell checking is done with the AutoSave and AutoSaveMac Class that use TimerTask to create a task that then runs every min. These Classes are used in the runAutoSave() function that runs on app initialization.
So I guess my question is how can I run the saving and spell checking in another thread when the user stops typing?
Please let me know if I can answer any other questions whatsoever.
EDIT: I've since started testing with the lines of code for the languagetool api removed/commented out. (In FXMLController.java and pom.xml) Way quicker for testing as the languagetool api takes a bit to load on run. I figure if i can get saving working when user stops typing then i'll easily be able to add the languagetool api code.
