Anyone have any advice for GUI debugging, and figuring out what is being triggered by certain events, especially

问题 So I have Entries which have some values assigned to them from a CFG File. I want to modify the CFG file when the Entry is updated, live, without a submit button; Using <Key> binding will work but will take only the previous value, not the current one, as the last key pressed is not taken into consideration as a value, but as a key-press .

问题 I'm doing a program in which there are 8 shapes contained in an array that will be displayed when you click the mouse. I am new to Java and not that familiar with event handlers and listeners.
