Fred beat me to it, Rafael, but here's an example of how I've used gridhittest.
I've forgotten where I pinched the concepts from so if this looks like
something that someone else here has offered in the past, I say thanks!
Here's a working example. Two columns of a grid bound to a table use checkbox
controls and I want to allow the user to check and uncheck as needed but I
don't want to allow cell selection in the grid. (Actually there are several
grids in this form and I have repeated as needed.)
Rather than bind directly to the mousedown event as in the example that Fred
linked to, I put codce like this in the mousedown event that just stores the
coordinates to a couple of form properties that I've added to my base form
class:
LPARAMETERS m.nButton, m.nShift, m.nXCoord, m.nYCoord
WITH thisform
.nGridX=m.nXCoord
.nGridY=m.nYCoord
ENDWITH && thisform
I have a form level method (markProject) that does the work. In the init of the
grid, I bind its click event to my form level handler method:
BINDEVENT(this,[Click],thisform,[markProject])
I then use gridhittest in that method to determine what to do. It looks like
this:
LOCAL m.lnRelCol, m.lnRelRow, m.lnWhere
STORE 0 TO m.lnWhere, m.lnRelRow, m.lnRelCol
This.pf1.pgProjects.grdProjects.GridHitTest(This.nGridX, This.nGridY, @lnWhere,
@lnRelRow, @lnRelCol)
IF m.lnWhere=3 && Cell
DO CASE
CASE m.lnRelCol=7 && column 7
IF projects.delivered
REPLACE projects.delivered WITH .f.
ELSE
REPLACE projects.delivered WITH .t.
ENDIF
CASE m.lnRelCol=8 && column 8
IF projects.complete
REPLACE projects.complete WITH .f.
ELSE
REPLACE projects.complete WITH .t.
ENDIF
ENDCASE
ENDIF
Hopefully that gets you started.

Subject: gridhittest
I have a form with 3 grids.
When the user hovers the mouse over any of the grids, I want to determine on
which column and row (ie wich cell) the mouse is hovering on.
I think I could determine where the mouse is on each grid by using gridhittest,
but I can't understand the explanation given on help or the examples found in
the web.
Can anyone post some code here to guide me, please?
