Do you want cell selection like a spreadsheet? If so, just use
setCellSelectionEnabled(true).

Otherwise, you can code your own mouse listeners and set the selection
of the grid however you want.

the first item gets selected rest all the items just come in to focus.

suppose i select a cell and drag my mouse over 5 cells the getselectedcell
count returns only one.
My reqmt is to select multiple cells at a time and perform a single
operation on it by right clicking on it.

Please help me out in this..

Thanks in advance

Cell selection is designed to allow for drag select. It works for me.

Can you send a code snippet that shows how you are creating the Grid?

I can't reproduce your problem. Using the same code below I can drag my
mouse and select multiple cells. Do you have any other special code
that could be changing the selection? What OS are you using?

Are you creating editors on top of the Grid? The editors will consume
the mouse events required for the drag select. The Grid cell selection
is not designed to be used in combination with editors that stay visible
for the entire lifetime of the Grid.

if(grid.getCellSelectionCount()!=0){

Point pt = grid.getCellSelection()[0];
System.out.println(+pt.x + "***");
System.out.println(pt + "&&&" + grid.getColumn(pt));
System.out.println("Well ID is -- "
+ well[pt.x][pt.y].getWellId());

the cell selection count is getting one every time when ever i drag my
mouse over the items.

are u sure ur getting cellselection count more than one every time
cause items are only coming in to focus but not getting selected.

Your code below is only asking for the selection count when a user
initially clicks the left mouse button... which is when the old
selection is cleared and a new drag selection is started. Thus there is
only ever one cell selected when a user clicks the left mouse button
(except when using CTRL or SHIFT). Listen to the selection event if you
want to get a callback every time the selection is updated. Read the
javadoc on addSelectionListener for more detail.

Hello , I am working on Nebula Grid something related to the above problem.
I have a grid , I select a cell-1 , Drag it down and on mouse release i have to copy down the text selected from cell-1 to all the cells dragged down.
I did a mouselistner

grid.addMouseListener(new MouseAdapter()
{
public void mouseDown(MouseEvent e) {
ViewerCell viewerCell = grid.getCell(new Point(e.x,e.y));
String cellText = viewerCell.getText();
System.out.println("Cell clicked: " + cellText);
}

Here I am able to get the text of selected cell , How do i add drag action to the mouse listner
I have tried to use
- mouseReleased(MouseEvent e)
-mouseDragged(MouseEvent e)
but it seems it doesnt work with Nebula grid
Please suggest a way.
