 How to add Horizontal Separator when using GroupLayout
I am currently using Java within another program called DOORS Rational Publishing Engine. I have successfully created a dialog box containing a number of questions with associated drop-downs next to each question using 2 columns within a sequentialGroup. The issue I have is that I want to separate the first 2 questions from the remaining 4 but I'm not sure how to have the separator extend through both columns. Here is the code I have thus far (keep in mind that I am not able to use native Java for this project, thus the javax.swing, etc.
Code:
var myFrame = javax.swing.JFrame();
var myPanel = javax.swing.JPanel();
var myLayout = javax.swing.GroupLayout(myPanel);
myPanel.setLayout(myLayout);
//Creates gaps between components
myLayout.setAutoCreateGaps(true);
//Creates gaps between components and window
myLayout.setAutoCreateContainerGaps(true);
//Horizontal axis component group
var hGroup = myLayout.createSequentialGroup();
var hComponents = myLayout.createParallelGroup();
hComponents.addComponent(WelcomeLabel);
hComponents.addComponent(ProjectLabel);
hComponents.addComponent(DocumentLabel);
hComponents.addComponent(FormalOptionLabel);
hComponents.addComponent(SCPLabel);
hComponents.addComponent(SCPNoteLabel);
hComponents.addComponent(DraftLabel);
hComponents.addComponent(AppendLabel);
hComponents.addComponent(SignLabel);
hGroup.addGroup(hComponents);
var moreHComponents = myLayout.createParallelGroup();
moreHComponents.addComponent(Welcome_Field);
moreHComponents.addComponent(Project_Select_Field);
moreHComponents.addComponent(Document_Select_Field);
moreHComponents.addComponent(FormalOption_Field);
moreHComponents.addComponent(SCP_Field);
moreHComponents.addComponent(EmptyLabel);
moreHComponents.addComponent(Draft_Field);
moreHComponents.addComponent(Append_Field);
moreHComponents.addComponent(Sign_Field);
hGroup.addGroup(moreHComponents);
myLayout.setHorizontalGroup(hGroup);
//Vertical axis component group
var vGroup = myLayout.createSequentialGroup();
var vComponentsWelcome = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsWelcome.addComponent(WelcomeLabel);
vComponentsWelcome.addComponent(Welcome_Field);
vGroup.addGroup(vComponentsWelcome);
var vComponentsProject = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsProject.addComponent(ProjectLabel);
vComponentsProject.addComponent(Project_Select_Field);
vGroup.addGroup(vComponentsProject);
var vComponentsDocument = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsDocument.addComponent(DocumentLabel);
vComponentsDocument.addComponent(Document_Select_Field);
vGroup.addGroup(vComponentsDocument);
//This is where I want the separator to appear spanning both columns.
var vComponentsFormal = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsFormal.addComponent(FormalOptionLabel);
vComponentsFormal.addComponent(FormalOption_Field);
vGroup.addGroup(vComponentsFormal);
var vComponentsSCP = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsSCP.addComponent(SCPLabel);
vComponentsSCP.addComponent(SCP_Field);
vGroup.addGroup(vComponentsSCP);
var vComponentsDraft = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsDraft.addComponent(DraftLabel);
vComponentsDraft.addComponent(Draft_Field);
vGroup.addGroup(vComponentsDraft);
myLayout.setVerticalGroup(vGroup);
I suppose my first question is whether this is even possible with a groupLayout? If it is, how would I do it?

Re: How to add Horizontal Separator when using GroupLayout
Is this java or javascript? The var statement is in javascript, not java.

Seems like var could be on its way to java. http://openjdk.java.net/jeps/286. My experience is it takes a while to get used to over explicit variable type declarations, but ends up making the code easier to read and still type safe.

Re: How to add Horizontal Separator when using GroupLayout
As I should have mentioned in my original post, I'm actually using what I would call quasi-java within DOORS RPE. I apologize for not being clear about that. While DOORS uses Javascript, I'm still, somehow, able to use java functionality to create dialog boxes. I have now figured out how to add the separator, but because of the setAutoCreateGaps, I have 2 individual lines with a gap between them. I'm not sure if it's possible to remove the space between the columns in a single row in the vertical axis group of a Java GroupLayout.
Code:
//Creates gaps between components
myLayout.setAutoCreateGaps(true);
...
... Add Horizontal axis groups for GroupLayout
...
var vComponentsDocument = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsDocument.addComponent(DocumentLabel);
vComponentsDocument.addComponent(Document_Select_Field);
vGroup.addGroup(vComponentsDocument);
//I'd like to, if possible, remove the gap between the 2 separators in this row
var vComponentsSeparators = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsSeparators.addComponent(hSeparator1);
vComponentsSeparators.addComponent(hSeparator2);
vGroup.addGroup(vComponentsSeparators);
var vComponentsFormal = myLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vComponentsFormal.addComponent(FormalOptionLabel);
vComponentsFormal.addComponent(FormalOption_Field);
vGroup.addGroup(vComponentsFormal);

Not a java(script) swing expert, but try searching for "javax.swing horizontal divider". There seems to be several code snippets, and while perhaps grouplayout may not work, there should be other containers that will.
