I i want to achieve a similar effort like the above which is the similar
to the setting of a table in Microsoft Word.When the mouse hover above a
column, te cursor changes to the one shown above (an arrow pointing
downwards) and upon mouse click, the entire column is selected. What do i
need to do to achieve this effect.

Please enlighten,
Regards,
Evon

Hi Evon,

I'm not sure exactly what EditParts you're using for your table - but you
have to override
getDragTracker(Request req) in your EditPart and return a customized drag
Tracker.

Your tracker should mostly extend SelectEditPartTracker and override the
performSelection method . You can easily use
EditPartViewer viewer = getCurrentViewer(); to get the current view and
methods like EditPartViewer#appendToSelection to modify the current
selection.

Have a look at how the SelectEditPartTracker is written and the methods
available in EditPartViewer as well.

To change the cursor - set the cursor for your figure using
IFigure#setCursor

All the best,
Brian.

Or the DragTracker could return the new Cursor whenever it was appropriate
by over-riding getDefaultCursor() or calculateCursor().

The drag tracker won't take effect until it is actually loaded on mouse
down.

Or use setDefaultCursor(Cursor)
