update URL when user changes the value of a cell

[ittarter]

In a basic table or datagrid, how would I get the program to response when a user changes the value of a cell, in such a way that the program knows which cell is being changed and can act accordingly (e.g. copy the changes to a URL)?

I'm envisioning the following scenarios. After changing the cell's value, the user:

-- tabs into another cell
-- presses the 'return' key
-- clicks anywhere in the app but outside the boundaries of the table/grid
-- clicks another cell
-- presses the 'up' 'down' 'left' 'right' key

Some of these I think I know (e.g. on keyDown up), but I don't know how livecode distinguishes between different cells in a way where I could get my program to know which item/line to validate/update.

Thanks

Hi ittarter,

check the chapter "Using The Built-In Field Editor" in the datagrid docs!
A topic I could avoid so far!

Hi ittarter:

Put the following code into your datagrid script:

Code: Select all

on closeFieldEditor pFEditor 
 local tCol, tRowIndex
   put  the dgColumn of the target into tCol # name of column edited
   put the dgIndex of the target into tRowIndex #gives the dgIndex of the edited row
  # now do whatever you want with these data
end closeFieldEditor

Pressing tab, return, etc., etc., will close the editor and call this handler.
This will only work with datagrid table, not form.

Regards,
Sri
