Re: [nebula-dev] Grid -How to obtain selected cell?

[zhong nanhai <higerinbeijing@xxxxxxxxx>]

Hi,

You should add a mouse listener to the grid object and implement its
onMouseDown method. In this method , you can get its point.  The code
may be like this:
grid.addMouseListener(new MouseAdapter(){
       public void mouseDown(MouseEvent e){
              Point pt=new Point(e.x,e.y);
              int columnIndex = grid.indexOf(getColumn(pt));
       }
});
In the above code, the pt variable is such a point parameter that
getColumn needs.

Regards,
higer
