If you want tooltips that are specific to each cell you can do something
like:

grid.addListener(SWT.MouseMove, new Listener()
{
public void handleEvent(Event e)
{
Point p = new Point(e.x,e.y);
GridColumn col = grid.getColumn(p);
GridItem item = grid.getItem(p);
//determine if the col and item have changed from
//previous saved values (i.e. user just moving in new cell?)
grid.setToolTipText("MyToolTipText");
}
});

Regards,
-Chris

Hi krishna,

That's better and here's the answer.

Checkout the following classes from JFace-Head:
-http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org .eclipse.jface/src/org/eclipse/jface/window/ToolTip.java
-http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org .eclipse.jface/src/org/eclipse/jface/window/DefaultToolTip.j ava
Although they are in JFace 3.3 you can use them without problems in 3.2.
The checkout the http://tom-eclipse-dev.blogspot.com/ to see how they
are used.

If you are using DefaultToolTip code looks like this:

---------------------8<---------------------
protected boolean shouldCreateToolTip(Event event) {
Point p = new Point(event.x,event.y);
GridItem gi = grid.getItem(p);

for( int i = 0; gi != null && i < grid.getColumns().length; i++ ) {
if( gi.contains(p) ) {
setText("ToolTip: " + gi.getText(i) );
return true;
}
}

return false;
}
---------------------8<---------------------

I assume in the code above that Grid is working the same as SWT-Table
but Chris can tell you more. I haven't tried to run this code myself it
simply should get you started. Give it a try and report back if it works
for you.

Wrong please reread the snippet from Chris:
------------------8<-------------------------
GridItem item = grid.getItem(p); // This is the row
------------------8<-------------------------
