develop a simple javafx json file editor with hierarchy display

Json file example attached.

The editor GUI:

- javafx window with a tabletreeview with these colums:

. Settings: read only column. Displays json file parent node hierarchy. Nodes are named with the json node "name" attribute (refer to attached json file example)

. Value: editable column for leaf nodes ONLY. leaf nodes only. Editable cell by default, combobox when the "list" attribute is set. A button is added on the edit cell or on the combobox when the json node attribute "button" is set

. Help: read-only column. Displays the node help text when the json node attribute "help" is set.

- the tabletreeview fits the entire window content => tabletreeview resized when window is resized

- one menubar with following items:

. save: save json file with modified values

. restore default: replace selected node child leaf node values with the json leaf node "default" attrinute value. Important: when a parent nodeis restored, all child leaf nodes are restored

- quit: save json values and close app

Read/save json file:

the json settings file is located in the same folder than the jar file. Use gson api to read/write file:

import [login to view URL];

BufferedReader bufferedReader = new BufferedReader(new FileReader(path));

Gson gson = new Gson();

HashMap<String, String> json = [login to view URL](bufferedReader, [login to view URL]);

Creating tabletreeview nodes is then straightforward, create node class with one hashmap as private attribute copied from gson read hashmaps => required to manage later fxml dialog controller enhancements ;)

Dialog controller:

- must manage value changes from editcell and combobox. "list" json node is used to fill the combo. The list is a comma separated list of (displayed combo item, item value) => only combo items are displayed in combo, but item value is used to fill json node value attribute and select combo item.

- button action (if any) must call a controller method with the clicked node json attribute as value
