How do I create subheading in JTables or JXTable

I want to create a table which has 2 columns... say column 1 and column2. Column 2 has more further divisions to create another 2 column (say A and B).
Im not sure on how to express my question better so I just painted out the kind of table I wanted. Please check the image and provide techniques on how it can be done using either JTable or JXTable?
Check the link for the table Im expecting:

Thanks.... exactly what I was looking for!! But was hoping for a simpler way or something integrated with JXTable. Never mind... just used the updated code ( http://www.swebb99.f2s.com/GroupableHeader/ ) for jdk5

Hi,
This piece of code will help :
     //Get the Component Adapter for taking action against resizing of
//of Panel
ComponentListenerAdapter componentAdapter =
new ComponentListenerAdapter()
//Get the scrollbar or remove the scrollbar upon resizing
protected void resizingAction()
Container tableParent = table.getParent();
if (tableParent instanceof JViewport)
//Check if the width of the Table Parent Container
//is less than the Preferred Size of the Table
if (tableParent.getSize().getWidth() <
table.getPreferredSize().getWidth())
//Yes it is
//Remove the Auton Resize Function and get the
//Scrollbar
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF );
else
//No it is not
//Get the Auto Resize functionality back in place
table.setAutoResizeMode(
JTable.AUTO_RESIZE_SUBSEQUENT_COLUMNS);
//Add the component Adapter to the Table Header
table.getTableHeader().addComponentListener(componentAdapter);
private abstract class ComponentListenerAdapter
implements ComponentListener
          * The <code>componentHidden<code> method has no implementation
          * @param event The Event occured whenever the Component is Hidden
          public void componentHidden(ComponentEvent event)
               //No Implementaion - Intentially Left Blank
          * The <code>componentShown</code> method has no implementation

          public void componentMoved(ComponentEvent event)
               //No Implementaion - Intentially Left Blank
          * The <code>componentResized</code> method is invoked whenever the

How do I create a JTable with some empty cells in it?

I have a three column JTable. The first column is a String showing description. The second column contains numbers (double) and the third column also contains numbers. In some cases not all cells in a row should contain data. So for instance, I could have row one showing only description (a String in the first column), and then row two showing description (a String in the first column) and a number (a double in the second column) in columns one and two respectively. My problem is that, the data gets copied from the cells with data to the cells which are supposed to be empty. So, how do I create a JTable with some empty cells in it.

I have tried empty strings for those values, but it did not work. My table puts objects in an arraylist called reconciliation. The arraylist takes different objects with the same super class. The code below explains. Are you suggesting I pass null to my constructor?
JTable table = new JTable(new ReconTableModel());The method below is from the table model
protected List<Reconciliation> reconciliation = new ArrayList<Reconciliation>();
protected void fillModel(){
      reconciliation.add(new CashBook("Cash Book Report"," "," "));
      reconciliation.add(new CheckingBankAccount("Checking Bank Account"," "," "));
      reconciliation.add(new BankBalance("Bank Balance As Per Bank Statement",500," "));
      reconciliation.add(new PaymentVouchers("Payment Voucher Receipt",300," "));
      reconciliation.add(new DepositVoucher("Deposit Voucher Receipt",1000," "));
      reconciliation.add(new ReconciledBalance("Reconcilied Bank Balance",1200," "));
      reconciliation.add(new BalanceAt("Bank Balance At",800," "));
      reconciliation.add(new Difference("Difference",400," "));
      Collections.sort( reconciliation, new Comparator<Reconciliation>(){
      public int compare( Reconciliation a, Reconciliation b) {
        return a.getTransactionName().compareTo( b.getTransactionName());
}

Query by example - how can I display VCRow in JTable?

I would like to provide the user with a searchable table.
Actually I would like to use two tables: one, displaying one row where the user can specify the search criteria. And the second table should display the data found.
I could store the entered criteria locally in a hashmap in TableModel, for example, then create a WHERE clause. This solution is quite messy, since the user can add, remove and rearrange the columns of both tables.
Or I could use -I hope- the query-by-example feature, like this:
am = app.getApplicationModule();
ViewObject vo = am.createViewObject( "MyVO", "mypackage1.PatView" );
ViewCriteria vc = vo.createViewCriteria();
ViewCriteriaRow vcr = vc.createViewCriteriaRow();
Now I can set attributes and use vo.applyViewCriteria() to find my data.
But how can I bring the first JTable to display this single ViewCriteriaRow, so that the user can do the editing?
The JUNavigationBar does it, if I am not mistaken. It switches the PanelBinding to find mode, and then a JTable displays a ViewCriteriaRow (?) instead of the ViewObject's data. But I don't want to use the bar. How do I create this behaviour manually?
The javadoc of JUPanelBinding says:
"Sets this panel and all its associated iterators into find mode."
So I guess that setting iterators into find mode is what I need. But I cannot figure out how to do that. Who can?

You cannot set the iterators in a panelBinding to separate find/data modes individually.
However you can create two JUPanelBinding objects one for the findMode form and one that displays Data.
here's what I did to modify a generated SingleForm, to display two panels of the same type one in find mode and other in data mode.
I changed the jbInit method of the "LayoutPanel" class to be like:
//declare this as a member of the class.
JButton findBtn;
public void jbInit() throws Exception
// Panel layout
masterViewPanel = new PanelDeptView(panelBinding);
//create another instance of PanelBinding for a second (findform) DeptView panel.
JUPanelBinding binding = new JUPanelBinding("Project3.Mypackage1Module", this);
binding.setApplication(panelBinding.getApplication());
masterViewPanel1 = new PanelDeptView(binding); //create second instance
findBtn = masterViewPanel1.navBar.getButton(JUNavigationBar.BUTTON_FIND);
findBtn.doClick(); //set the second instance in find mode.
//add a listener on the second instance's execute button so that it resets the form into find mode
//this forces the second instance to be in find mode when execute button is pressed.
masterViewPanel1.navBar.getButton(JUNavigationBar.BUTTON_EXECUTE).addActionListener(new ActionListener()
public void actionPerformed(ActionEvent ev)
SwingUtilities.invokeLater(new Runnable() {
public void run()
findBtn.doClick();
this.setLayout(panelLayout);
add(masterViewPanel, BorderLayout.WEST);
//add the second instance.
add(masterViewPanel1, BorderLayout.EAST);
I also had to call findBtn.doClick() again in the "constructor" that takes (JUApplication, boolean) after the panelBinding is executed,
to force the initial startup of this panel in findmode

Creating and filling JTables dynamically

Hello,
How can I create and display a JTable dynamically in a Java application? In my application, I retrieve rows from a database and therefore I don't know in advance how many rows I need for my JTable (using the tablemodel). I tried to solve the problem in the following way:
1)start op applicatie with a JTable with 0 rows (screen is grey, only columns are visible)
2)run query and count number of rows.
3)create new JTable based on number retrieved in step 2 and tried to put it onto the screen.
4)run query again and fill table with values retrieved from query
The bottleneck so far is step 3. I can create a new table but I don't manage to put it onto the screen (i tried already the repaint() method)
Thanx for you help
Frits

Sure, no problem. Assume you've retrieved the following result from the database:First Name     Last Name     Age
John           Doe           25
Jane           Doe           27
Joe            Smith         40
Mary           Smith         19You create your JTable as like this:Vector headings = new Vector();
Vector rows = new Vector();
Vector cells = null;
JTable table = null;
for(int x=0; x< resultSize; x++){//resultSize is the size of your result
cells = new Vector(); //Cells together will represent a row
cells.add(yourResult.getTheFirstColumnForRowX()); //Pseudo-code
cells.add(yourResult.getTheSecondColumnForRowX()); //Pseudo-code
cells.add(yourResult.getTheThirdColumnForRowX()); //Pseudo-code
//Now place those cells into the rows vector
rows.add(cells);
//Create the JTable
table = new JTable(rows, headings);This code is not tested and is meant to give you an idea of how the concept can be applied. Hope it helps.

How to Connect MySQL Database Through JTable?

Hi,
How to Connect MySQL Database Through JTable? anyone of u knows these concept please send me coding of that Part..
Thanks,
Guru..

Start by reading the tutorials. There's a section on Swing which shows you how to use tables and a section on JDBC which shows you how to use SQL.
And you can always search the forum as well since there are working examples of both posted on the forum.
If you need further help with a specific problem then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the [Code Formatting Tags|http://forum.java.sun.com/help.jspa?sec=formatting], so the posted code retains its original formatting.

How can i create a new usb connection (service) on my iMac for sharing internet from my iPhone5 ( i seem have to deleted it )
i know its not a problem whit my carrier o data plan or sharing preferences on the ipone because when i use it un my laptop it works perfectly through
the usb and even works on the Imac through wifi and bluethood tethering but NOT through usb!!.
the problem is that trying to make it work i deleted the "profile" usb iphone on the network prefereces panel. Now i only have 3 options: ethernet / wifi / bluetooth
but not the usb iPhone i used to have.
And when i try to add a new one i dont get a USB option.
can some one help me please??
this is how it looks (after the bluetooth PAN i used to have USB iPhone option)

The question would be more appropriate in the Mac forums as it is not really related to the iPhone.

How can I create a new layer that is a gradient?

Hi, i'm very new to photoshop scripting and am having some trouble.
I'm looking for a way to take an image i have and set it to have a gradient opacity as it approaches the middle, my thought on how to do that was to just create a layer that is a gradient from top left to bottom right and then attach that as a vector mask.
Any ideas on how I could create this gradient layer in script, or a better method of doing this opacity gradient?
Thanks in advance,
Levianth

You could try this:
// 2012, use it at your own risk;
#target photoshop
if (app.documents.length > 0) {
var myDocument = app.activeDocument;
var theLayer = myDocument.activeLayer;
if (theLayer.isBackgroundLayer == true) {theLayer.isBackgroundLayer = false};
// create gradient layer;

How do I create a new icloud email address for my apple id?

Hi there
How do I create a new icloud email address for my apple id? My original email address is associated with my previous employers.
When I send email from my Macbook, it seems as if I still work there, which is a problem.
I would like to use the email address that I created for my iPad.
When I login with my appleid (for my macbook) I keep getting the old company one, not the new one.
Is there any way of resolving this? I
Thanks

How can I create a new ring tone for my iPhone 4?

How can I create a new ring tone for my iPhone 4? I followed the Garage Band process and ended up with the ring tone I want as a AAC audio file. It got stored in my iTunes a a song rather than a ring tone. How do I make it a ring tone vs. a song? I tried dragging it t the Ring Tone category at the bottom of the ITunes list, but it won't alloow me to move it?

There's also an easy to use Applescript over at Doug's Applescripts for iTunes. It automates the whole thing. All you do is set the start and stop time on a file in iTuens and run the script. It will do everything else.
