Hi Rudy,

yes of course I tried all this by myself. With my scenario, in way of working, 
in my samples.

But I think that this goes beyond the purpose of this discussion list. I think 
discussing possibilities would not help you. I recommend you to contact your 
local 4D support subsidiary. And the best would be to have an example ready to 
give them. Then they can check if it is a problem of your way of working, if 
you have to use a different approach or yes, if it might be a bug in 4D

Achim.

Betreff: Re: 4D Write PRO: editing a table / collections

Achim, have you tried this yourself?

I think it is not possible in 4D Write PRO v17 to select 1 or more cells in a 
table and then be able to get the cells reference by code.

Just follow this scenario:

- the user creates a table in 4D Write PRO (by clicking a button containing the 
code WP Insert Table)
- Basically, the developer provides a dialog to ask for the number of columns 
and rows, and eventually column width, background color etc.
- the table will be created in the 4D Write PRO document, where the user can 
add content.

Now, the user wants to change attributes of the cells, or columns. i.e. width, 
color, borders. In order to do that (in code), the developer needs to know 
which cells have been selected.

In the table, the user can select 1 or more cells, but here’s the problem: how 
to find out which cell(s) have been selected?

WP get selection will return an object with a ’start’, ‘end’ and ’type’ 
attribute. Type is always = 0, start and end e.g. 32,40 do not give any clue as 
to which cell is selected.
Interestingly, WP Create table range returns exactly the same result, but type 
= 4

‘WP Get position': nothing that can be used: While the user has selected cells 
1 and 2, we get this result:
‘column’ = 1
‘line’ = 3
‘page’ = 1
‘position’ =1

'WP GET ELEMENTS' will return a collection, where the table object can indeed 
be found, but still no information about which cell or cells are selected.
‘WP Table Get Cells' will create a new range containing the specified cells, 
but NOT provide information about which cells are actually selected.
