Multiple columns Drag n Drop in JTable

Issue:
I'm building a JTable with groupable column headers like this:
GROUP A_ | GROUP B_
col1 | col2 | col3 | col4
I based this on the GroupableHeader example at: http://www2.gol.com/users/tame/swing/examples/JTableExamples1.html
Question:
How would I approach allowing the user to reorder Groups by dragging
the Group level header(GROUP A_) and all of its subordinate columns (col1 and col2) and dropping into a new location. I'd like to simulate the standard JTable column DnD animation - but with groups of columns.

Have you solved this problem ? I have the same question.

How Can I Put Multiple Columns in a Drop-Down Menu?

We are trying to put multiple columns in a drop-down menu, similar to what is on these web sites...
http://www.cabelas.com/
http://www.target.com/ (This site has the multiple columns on the Women, Home, Kitching & Dining, Toys, Electronics, and See More categories).
If anyone has any suggestions for coding, please reply.
Thank you.

As an <li> tag is not a block level element like a <p> or <div> tag you can store a <div> container within the <li> tag and create an element in that menu item and us the following tutorial to create multiple columns depending on the ordering:
http://www.alistapart.com/articles/multicolumnlists
Depending on your target browser you could also use the CSS3 column-count to define the amount of columns. But with just a quick glance at this I would say it only works in the the later versions of Firefox, Chrome, Safari and IE9+.

MULTIPLE-ROW drag and drop between 2 ALV grids

Hi,
Can anybody help me with acheiving MULTIPLE-ROW drag and drop functionality between 2 ALV grids.

hi Prakash,
Actually I'm trying to develop multiple drag and drop between 2 ALV's. To understand the events properly, I started working on this sample program where it uses 1 ALV and splits it into 2 and uses single row drag and drop between them. Now I'm making it to work for multiple drag and drop, so that I can use it on my application. This is the code which I'm working on..
*& Report Z_ALV_GRID_CONTROLS_DRAG_DROP                               *

Is it possibiel to disable drag and drop of JTable columns?

Hi,
Using JDK6 I would like to disable user to drag and drop columns and change the default layout of my JTables.
Thanks for any help,

Using JDK6 I would like to disable user to drag and drop columns Read the JTableHeader API. You can prevent reordering of the columns.
and change the default layout of my JTables.How do you expect us to answser this??? What do you mean by changing the layout? Whats wrong with row and column and what do you want to change it to?

How to Create Table Using Column Drag and Drop Feature

Hi:
I am new to Oracle SQL dev Data Modeler tool and would like to know if there is a way to create a new table by re-using the existing columns or column groups. The idea is to maintain consistency and save table design time. If columns created previously can be re-used and require drag and drop of column in the right pane, then only new columns need to be manually created.
Any thoughts on this will be appreciated.
Thanks!

Hi Kent
I checked out the video and tried it in Oracle designer, it works and works great!
My other question is that I may have several set of columns that I may want to group depending on the table requirements. Can I have multiple templates and choose which one to apply to?
Also, how do I choose the table where the table template needs to be applied. As I may be interested in applying the table template to selected tables only.
Thanks

Multiple Item Drag and Drop

I'm working on an application where I need multiple item DnD between JTrees and JTables. I'm using Java 1.4.1
I have the basics of multiple item DnD working, by creating Transferable classes that contain a collection of items.
The problem I have is when I drag a multiple selection within a JTree (i.e. DragSource and DropTarget are the same) then my call to event.getCurrentDataFlavors() in my dragOver(DropTargetDragEvent event) method is not returning any data flavours unless I drag over to another JTree. If I now drag back over to the source JTree (so that DragSource and DropTarget are again the same) as if by magic I now get DataFlavours whilst dragging over the source container.
This is driving me nuts! :-)
Has anybody else seen this and do they have a solution?

I have the same problem here.
When I try to perform drag and drop in a JTree (DragSource and DropTarget are the same), calling event.getCurrentDataFlavors() in the dragOver(DropTargetDragEvent event) method in the DropTargetListener returns me nothing!!
However, the call of event.getCurrentDataFlavors() in the
drop(DropTargetDropEvent event) does return me the correct
information.
On the doc, the DropTargetDragEvent.getCurrentDataFlavors()
should mimic DropTargetDropEvent.getCurrentDataFlavors().
So, I suppose both functions should work in the same way
properly.
Is there anything wrong with my understanding or is that a bug
of the Java dnd?

Drag n Drop in JTable with AbstractTableModel

Dear Experts,
I would like to drag and drop rows in a JTable. For example, if I have 6 rows in a JTable based on an AbstractTableModel and if I am trying to drag row number 5 and wish to drop it at row number 2, then the 5th row which was dragged should be pasted as 3rd row and the rows 3 and 4 should be rearranged (ie, moved one place down).
Can anyone help me in achieving this? Any readymade code available? :-)
I tried running the code in the Java Tutorial in the link
http://java.sun.com/docs/books/tutorial/uiswing/examples/dnd/index.html
but, this didnt help as it was mainly for a DefaultTableModel I guess. Also, when I used the StringTransferHandler and TableTransferHandler, I was able achieve just copying the dragged row and pasting at the dropped row. The row rearrangement was not functioning.
Pls Help...
Thanks & Regards
Irfaan

I have 6 rows in a JTable based on an AbstractTableModelDo you know what "Abstract" means? I suggest you look it up in your Java text book.
You are not using the AbstractTableModel, you are using a TableModel that extends AbstractTableModel.
but, this didnt help as it was mainly for a DefaultTableModel That is exactly why you should be using the DefaultTableModel since it supports the concept of moving rows. If you want to use a custom TableModel, then you need to implement the concept of moving rows yourself. So why write a custom TableModel when this has already been done for you??

Drag n Drop In Jtable

Hiii Guys......
I need a code for drag n drop feature in JTable.
i need that, i should be able to interchange value of two cells in the same Jtable with drag n drop..... with values getting changed in the database also......

What code have you written so far?

Drag N Drop in JTables

Hi !
I have two scenarios
1) I need to be able to drag and drop rows from a given table to the other table.
2) I should be able to drag and drop rows with in the same table( This case is same as rearranging the rows with in the table with the help of MouseDragged Event).
Is this possible using Drag N Drop in swing? Greatly appreciate solutions and online resources which can help me write my custom TransferHandler for the above purposes

Ok, here's the promised source code
When the Class is initialized you need to create a couple of objects
          DragSource dragSource = DragSource.getDefaultDragSource() ;
          dragSource.createDefaultDragGestureRecognizer(this, DnDConstants.ACTION_COPY_OR_MOVE, this) ;And you will need the following method
     public void dragGestureRecognized(DragGestureEvent e) {
          String v = (String) getSelectedValue() ;
          e.startDrag(DragSource.DefaultCopyDrop, new StringSelection(v), this) ;
     }or a variation on it. You will of course need the imports and such to support these, but most of it is in the java.awt.dnd package.
Then in your target you'll need a method to catch the drop ...
     public void drop(DropTargetDropEvent e){
          try{
               DataFlavor stringFlavor = DataFlavor.stringFlavor ;
               Transferable tr = e.getTransferable() ;
               if(e.isDataFlavorSupported(stringFlavor)){
                    String name = (String) tr.getTransferData(stringFlavor) ;
                    e.acceptDrop(DnDConstants.ACTION_COPY_OR_MOVE) ;
                    Point p = e.getLocation() ;
                    int x = Integer.parseInt(String.valueOf(Math.round(p.getX()))) ;
                    int y = Integer.parseInt(String.valueOf(Math.round(p.getY()))) ;
                    int i = lastScenarioIndex++ ;
                    addDrawingObject(
                         new ScenarioDrawingObject("SCENARIO_" + i, "SCENARIO_" + i, y, x,
                         new SequenceMemberDrawingObject(name, name, 20, 20))) ;
                    resizeContainer() ;
          catch(IOException ioe){
               ioe.printStackTrace() ;
          catch(UnsupportedFlavorException ufe){
               ufe.printStackTrace() ;
     }There's a little more to it, but that's the crux of it.
Cheers.

Drag and Drop in JTable never gets DropTargetListener events

I'm trying to implement Drag/Drop between two JTables. I have adapted the source from the Drag/Drop Tutorial but none of the DropTargetListener events get called. When I try to drag a row from one table to the other, the debug output is as follows:
beginning drag : ROW 3
dragsource : dragExit
dragsource : dragDropEnd
I'm using JDK 1.3. Any help would be appreciated, here is the source:
public class DnDTable extends JTable implements DropTargetListener, DragSourceListener, DragGestureListener
public DnDTable(Object[][] rowData,Object[] columnNames)
super(rowData,columnNames);
m_dropTarget = new DropTarget(this,this);
m_dragSource = new DragSource();
m_dragSource.createDefaultDragGestureRecognizer(this,DnDConstants.ACTION_MOVE,this);
public void dragEnter(DropTargetDragEvent event)
System.out.println("droptarget : dragEnter");
event.acceptDrag(DnDConstants.ACTION_MOVE);
public void dragExit(DropTargetEvent event)
System.out.println("droptarget : dragExit");
public void dragOver(DropTargetDragEvent event)
System.out.println("droptarget : dragOver");
public void drop(DropTargetDropEvent event)
System.out.println("droptarget : drop");
try
Transferable transferable = event.getTransferable();
// we accept only Strings
if (transferable.isDataFlavorSupported(DataFlavor.stringFlavor))
event.acceptDrop(DnDConstants.ACTION_MOVE);
String s = (String)transferable.getTransferData(DataFlavor.stringFlavor);
setValueAt(s,rowAtPoint(event.getLocation()),0);
event.getDropTargetContext().dropComplete(true);
else
event.rejectDrop();
catch(IOException exception)
exception.printStackTrace();
System.err.println( "Exception" + exception.getMessage());
event.rejectDrop();
catch(UnsupportedFlavorException ufException )
ufException.printStackTrace();
System.err.println( "Exception" + ufException.getMessage());
event.rejectDrop();
public void dropActionChanged(DropTargetDragEvent e)
public void dragGestureRecognized(DragGestureEvent event)
int nDragRow;
Object object;
nDragRow = getSelectedRow();
object = getValueAt(nDragRow,0);
if (object != null )
System.out.println("beginning drag:" + object.toString());
StringSelection text = new StringSelection(object.toString());
m_dragSource.startDrag(event,DragSource.DefaultMoveDrop,text,this);
else
System.out.println("nothing was selected");
public void dragDropEnd(DragSourceDropEvent event)
System.out.println("dragsource : dragDropEnd");
public void dragEnter(DragSourceDragEvent event)
System.out.println("dragsource : dragEnter");
public void dragExit(DragSourceEvent event)
System.out.println("dragsource : dragExit");
public void dragOver(DragSourceDragEvent event)
System.out.println("dragsource : dragOver");
public void dropActionChanged(DragSourceDragEvent event)
System.out.println("dragsource : dropActionChanged");
DropTarget m_dropTarget;
DragSource m_dragSource;

Hi My friend,
The code you have took will perfectly works.
I have an option please try this.
Instead of DnDConstants.ACTION_MOVE try DnDConstants.ACTION_COPY.

Drag and Drop in jtable!

Hi everybody!
I want drag some element from some list and drop in some cell in jtable, but i have a problem because this element can use more than one cell, all depends! , the drag moviment seem to work fine between list and the JTable. when the drag cursor is above a row in the JTable, ONLY ONE cell in that row is highlighted, but i want that more than one cell get highlighted and i want put the information in more than one cell.
Anyone know how to do that?
thanks in advance
ps:I am a freshman in foruns, sorry about my english.

Drag and Drop inside JTable: what draws the 'insert' line during the drag?

I'm trying to reconfigure a rather complex table with a fair number of custom renderers to include drag & drop of rows for resorting the table. Everything is working great, except that as I drag the rows there is no indication of the current insert point (i.e. the line that appears between rows). When I make a simpler table I see the line... I'm not sure what aspect of my current table is blocking this function. I'm writing in the hope that can someone can direct me to the method(s) responsible for drawing this line.
Thanks!

To elaborate a bit for anyone who might read this. I inquired with the Substance developers and they hope to support this feature in v5.1 (which requires SE6), but have no plans to update v4.3 (the last release before a switch to SE6).
Also, I'd still be grateful for any info pointing me to the Swing methods that draw the drag line.

Drag and Drop from JTable

Using cntl C and cntl V to copy data from a JTable
into another file
j2sdk1.4.0 copied the column names along with the data.
j2sdk1.4.1_04 does not copy the column names anymore.
Is there any way to get the previous functionality?

Does anyone use cut and paste to copy data from a JTable to another file?
I wonder why the new RE-Version doesn't copy the column headers anymore.

What does it take to drag and drop a jTable row to a jTextField?

What kind of Listeners do I need? I have implemented transferListener and overrode createTransferable. But there was nothing responding when I tried to drag a row away. Any other Listener do I need to implement?

For better help sooner, post an SSCCE.

Disable JTable Column dragging?

How do you disallow the user from moving the order of your columns in a JTable? They are able to select data within the column, but I don't want them to change the order of the columns (drag and drop the columns). Thanks for any help/suggestions in advance. --Dean

JTable table = new JTable(...);
JTableHeader header = table.getTableHeader();
header.setReorderingAllowed(false);Mitch Goldstein
