I wrote a program that asks the user to enter some information, does some calculations and tells them what they need to order. I know there is a way I just do not know how to do it. I would like the output from the program which is presented in text fields to be printed onto a form I made in excel when a button is pressed.

Having trouble adding leaves to my tree. Developing a stand alone Java app using mainly SWT and Eclipse JavaEE on Windows.The tree is like this:
root
------parentA
--------------childA1
--------------childA2
--------------childA3
------parentB
------parentC
--------------childC1
--------------childC2
My requirement: when a child is selected/clicked I want to create a grandchild (there could be from zero to say 12 grandchildren). Thus if user clicks/selects childA2:
root
------parentA
--------------childA1
--------------childA2
----------------------grandchildA21
--------------childA3
------parentB
------parentC
--------------childC1
--------------childC2
Codewise I have:
import org.eclipse.swt.widgets.Tree;
import org.eclipse.swt.widgets.TreeItem;
Question one: do I need any further tree related imports to get this to work?
final Tree tree = new Tree(shell, SWT.VIRTUAL | SWT.BORDER | SWT.CHECK | SWT.V_SCROLL | SWT.H_SCROLL | SWT.SINGLE );
tree.setHeaderVisible(true);
tree.setBounds(975, 00, 375, 600);

And it is here I've tried lots of options but it's like bleak mid winter - no new leaves What seems odd is that I can see the selected/clicked child text item.getText() but if I look at the index it is always -1. And I thought the index would let me create the leaf.
I am tasked with creating several JPanels each of which has a title centered at the top. As such I have created parent panel that each panel extends.

Is it good practice to create a inner class for layered panels with lots of components? In my opinion this makes the code easier to read and a lot less clustered.
View Replies View RelatedWill the code below just create a new blank window rather than call the one I have? I want to call the one I have from my main method ideally.

I need to use a counter to keep track of user's input. In this class I am trying to create a combination lock that takes three strings. In the tester class the user inserts three strings and both are compared to see if users input matches correct combination. I have no errors only problem is the setPosition method. My output is always false.
public class CombinationLock {
private String first;
private String second;
private String third;
private String firstGuess;
private String secondGuess;
private String thirdGuess;
private boolean open;
private int counter;

I'm building a text editor. At this point, the editor should be able to read and write text and rich text. I create an instance of a RichTextEditor class that I created that extends a superclass I created (that extends JTextPane). Both my rich text and plain text classes extends the superclass I created. I use the this.read() to input my plain text from buffered reader. I think I need to use the read(fileinput stream, rtf document) method from type RTFEditorKit, but I cannot use that because it does not extend RTFEditorKit. I don't want to create a new class that extends RTFEditorKit because I need stuff from the JTextPane.
here are the classes on git... the super: TextEditorPane.java
The plaintext: TextEditorWrap.java
and the rich: RichTextEditor.java
I have fiddled with the read() method in different ways. In all cases, nothing loads. If I use the BufferedReader method, it doesn't give me an RTF, just the code for the RTF file.
How should I proceed? Do I create some sort of RTF interface and implement it?

Not sure why this code isnt working for me, it makes an empty excel file called output, but never copies the contents in "myfile" to that output file. I have Excel 2010 but I saved both of them as 97-2003 workbooks. Am I missing something? Do you have to go cell by cell to copy an excel file with JXL?
