But I am pretty much confused on how to enable any interaction with my chart and need some help to this. I'd be very grateful for any help in the right direction.

问题 When you right click on a TextField there are Undo, Redo, Cut, Copy, Paste, Delete, and Select All options. I want to add a "Register" MenuItem to that list from my controller class, but do not know how.

问题 In my application I have a screen where I use Accelerators. I'm using the function key F3 to execute an operation in my application. It works fine everytime, but when I click in any TextField on this screen the function key doesn't execute. Here is the code where I set the Accelerator: scene.getAccelerators().put( new KeyCodeCombination(KeyCode.F3), new Runnable() { @Override public void run() { // do sth here } } ); When I click my textfield and then hit the F3 function key it doesn't work.

I found the following (Properties omitted because of sensitive/irrelevant information): <delete dir="${store.dir}"/> <mkdir dir="${store.dir}"/> <jar destfile="${store.dir}/temp_final.jar" filesetmanifest="skip"> <zipgroupfileset dir=
