KTable merging mechanism help!! [message #467363] Mon, 30 January 2006 12:33 Go to next message

Hi all,

I need to implement some spreadsheet functionalities in my application,
my first requirement is to a teble with have two-row(headers ) where the
first row need to merge one or more columns for example:

--------------------------
| A | B |
--------------------------
| A1 |A2 | B1| B2 | B3 |
--------------------------
| | | | | |
--------------------------

For this reason i've try the Ktable components because i've seen from a
screenshot on the sourceforge site that this is possible.

I found this component very good, specially for the model concept.

My problem is that there's no documentation, and i don't understand how
to customize the components for my needings.

I've seen the Span Examples but this is too much simple and i don't
understand how it works ( i've already see at the code in the
doBelongsToCell but i'm not an SWT expert and it's not very clear ).

My questions are:

Is the code for the screenshot ( in the sourceforge site ) available???

Are there any documentation about this component??

Thanks

Andrea

Hi,

Sorry, currently there is only the example code with very minimalistic
cell spanning.

The concept of belongsToCell() is that this method is called by KTable
to get the left-top-cell of a spanned cell.

So if you want to implement a table just like you have sketched it
below, for the first row you would do:
- return (0,0) for the indices (0,0) and (1,0),
- return (2,0) for the indices (2,0) and (3,0)
....
and so on. This is the way to say that, for example, both (0,0) and
(1,0) should belong to the same, merged cell.

If you have more detailed questions, ask them here...
