Java Application for tracking monthly income and balance pt2

New week, new post. I'm almost done with my little application described in the last post , I need to do only the pop up message when closing and I need to do some fixes to the layout, as you can see in the screen below.

You can find the full code at my repository on GitHub, and here is the part of code which make me mad:

I'll try to use multiple pane, and so multiple layout manager, to resolve this damn layout, as explained here. When I fix I post everything.

Java Application for tracking monthly income and balance

As I say in the very first post, I use this blog as worklog for my personal project, and since with my Arduino Starter Kit explanation I'm blocked (I don't have a 9V battery, and neither the time to go out and buy it, shame on me), I'm now working on a little project that I have in mind from long time.

For tracking my personal bank balance, inasmuch as I found the movement list in my home banking not useful, I usually use an Excel file that do simple calculation and return how much money I can spent over the month. So why not write this in java using Swing?

So here a simple analysis:
Monthly Income (shortened in MonIn), is a simple java application which read a file with some hashtag inside, each tag define a value.
Using Swing GUI, display this data to video, then let you modify the data and calculate some total predetermined.

In the future I change the file I/O with a DataBase and relative query.

As you can see I'm a real artist when using MSPaint. 

The source file contains some tag in this form:

#tag1 = value1;
#tag2= value2;
...
#tagN=valueN;

The java.io package is needed to read and write to the file.

The Swing GUI contains the form with all the text field, a table, a button to make the calculation, a checkbox to enable advance setting.

in the future I change the form adding a tabbed pane

The first four text fields are JTextFields, tfAccrual is not editable (setEnabled(false)) and by default set to 200. Constant loss is a JTable, and contains only standard monthly expenses. By default is not editable.
CalcBtn is a JButton, which at click calc the total. Advanced Setting is a JCheckBox, if selected enable editing to tfAccrual and Constant Loss. Totals are three JTextField, not editable, when start application they contains the previous month total.
SaveBtn is a JButton, when pressed write the new value to the file (or in the DB).
This project use the GroupLayout as Layout Manager.
JFrame cannot be resizable in this application (setResizable(false));

On exit, using a WindowListener to check the exit before the closing action of the frame, if there are no unsaved modification then exit, else popup a message that ask if want to save before exit, the popup message is a JOptionPane.

On line documentation about these component and listener on Oracle Doc and Oracle Tutorial.

I the next days I'll post, alternating with Arduino, all the code and some image of this project.
