You wawnt to use the function
dwcontrol.GetObjectAtPointer ( )
>From the datawindow control help:
It reports the object and row number under the pointer. DataWindow objects
include columns, labels, and other graphic objects, such as lines and
bitmaps.
Return value:
String. Returns the string whose value is the name of the object under the
pointer, followed by a tab character and the row number. Returns the empty
string ("") if an error occurs. If dwcontrol is NULL, GetObjectAtPointer
returns NULL.
I used this to interact with dynamically created elements on a datawindow
with a lot of success.(I was abusing a datawindow - I used the datawindow as
a drawing area for a network graph, where the users could place new nodes
and interconnections between nodes.)
Put a call to this function from the mousemove event of the datawindow, then
parse the returned string to get the object name and row number.
Then all you have to do is check the object type, and get/display the
values for it where appropriate.
Hope this helps.
regards, Vivian.
