You are creating a new WindowEvent with
WindowEvent tabClosingEvent = new WindowEvent(this,....
and posting this to the event queue. The this here refers to the main frame. That's why it is closed.
However, you should usually not mess around with the event queue manually. Instead, you should do the respective actions programmatically with the method that perform the desired actions.
There are some parts of the code between the first { and the last } that might benefit from a slight cleanup, but in order to solve the actual issue, you could change your closeActionPerformed method to something like this:
private void closeActionPerformed(java.awt.event.ActionEvent evt)
{
Component c = tPane.getSelectedComponent();
if (c instanceof JInternalFrame)
{
JInternalFrame f = (JInternalFrame)c;
f.dispose();
tPane.remove(f);
}
}
(BTW: Then you also don't need the InternalFrameListener any more)

I am trying to update a JTextBox with data from a serial port in java swing. The problem I am facing is that the JTextBox is not getting updated.
I tried repaint() and revalidate functions also but not use. I also tried putting the setText() inside a runnable. Nothing works. Please guide me in this.

When a serial data is received, serialEvent is called in PortReader class which in turn calls the showSensorValueOnScreen() method in the PrinterUI class. The JTextBox widget doesnt gets updated.
But when a button on the UI is pressed, the JTextBox gets updated.
Why doesnt it get updated when I call it from outside the class?. Please help me out here.
I found out the issue. I am trying to update the UI from another class by creating a new object for the UI. The actual UI was created from void main using a different object.
I resolved it by passing the existing object to the class that was calling the UI update function.
Thank you for your help people.

Use the jlabel.setIcon(Icon icon) method.
Don't forget to use jlabel.revalidate() and jlabel.repaint() after update your GUI.
I want to write data in note pad by clicking that buttons.
By using using my code I tried to write in note pad it's not working. I want functionality like same as on-screen keyboard of windows. By windows on-screen keyboard we can write in note pad as well as in google chrome like that I want to create the application.
How can I create like that by using java ?
I tried below way but it's not working.

Some time ago, I've written a framework for such tasks. Maybe you find it useful (the library is Open Source):
Tutorial:
http://softsmithy.sourceforge.net/lib/current/docs/tutorial/swing/customizer/index.html
Javadoc:
http://softsmithy.sourceforge.net/lib/current/docs/api/softsmithy-lib-swing-customizer/index.html
Info about the latest release:
http://puces-blog.blogspot.ch/2013/11/news-from-software-smithy-version-04.html
There's no need to put a MouseAdapter within an already defined Listener. In fact, you're simply declaring one and not using it in any way. Simply keep it inside the dragged event.
Like this. You can adapt it to the calculations you need to do.
private void jPanel1MouseDragged(java.awt.event.MouseEvent evt) {
jPanel1.setLocation(evt.getXOnScreen(), evt.getYOnScreen());
}
Right I have now recreated my problem follow SSCEE guidelines.

So with all the code out the way, as I have just revised all of this I will mention what the issue is again.
When I go to ConfigWindow from MainWindow to select Options, after selecting options, a method in ConfigWindow gets the value of the selected button, and then a method in MainWindow gets this value, and sets it to a variable within MainWindow. Then on clicking Apply in ConfigWindow, the method from MainWindow should be run, setting the MainWindow variable with the option selected, however it doesnt!
I have trimmed trimmed trimmed my project to its most basic form, and now it throws an error in netbeans on clicking apply, whereas before it just didnt do anything at all, no error in netbeans.
I hope I've managed to fulfil SSCEE here ... I'm trying!!!
Here is the source, progressed over what you posted, compacted into a single source file. There are still problems to be fixed, but I put debug statements (printing out values) that should help to point out why it is still not working. See further notes at bottom of post.

A single source file is needed for an SSCCE, but at 253 lines, it is not really 'short'. If you removed those (quite superfluous and irritating) auto-generated Netbeans comments and deleted the unnecessary code block to set a PLAF (which has nothing to do with this problem) it would probably be less than 150 lines of code, which is probably short enough to call 'an SSCCE'.
Use a consistent and logical indent for code blocks. The indentation of the code is intended to help people understand the program flow. In Netbeans, this is as easy as pressing the key combination Alt+Shift+F
That code seen above is how my current version of Netbeans formats the code, though I suspect that newer versions will leave out the first indent in order to have method signatures start at char 0 on a line (giving more width to display them).
I strongly suggest you put Netbeans aside for the moment. Until you are familiar with basic Java, it will just get in the way.
This source uses 3 frames. An application would (should) typically only have a single frame for the main application window. The other two might be put into a JDialog or a JOptionPane. See The Use of Multiple JFrames, Good/Bad Practice? for more details.
Got this sorted in the end, I was completely over thinking the issue.

}
