Questions about the capability of a table / tableviewer [message #465345]

Hi,

I'm relatively new to Eclipse SWT. I'm trying to extend a basic SpreadSheet
app.

First, I'd like to be able to allow text to "spill" from a cell (like Excel
does when the adjoining column is empty)
Secondly, I'd like to offer "Intelli-sense" so that when a user types a
value, a drop-down appears that offers additional choices.

If any of this functionality might already exist, can anyone give me some
pointers? Or tell me if I'm completely out of luck.

I'm new to the group also, but haven't had much luck searching through
Google, or previous postings. Please forgive me if this has been addressed
before.

Thanks!

Hi,

I can only comment on going with ktable for such an app - which is a
custom widget and thus gives you high flexibility:

At ktable, currently cellrenderers are not allowed to draw over their
bounds. So the ony way implementing this - and probably an acceptable
one - is working with column spanning in such cases.

This probably can be done with a KTableCellEditorCombo - that offers a
CCombo to edit content.

KTable was originally written for applications that need
spreadsheet-like UIs, and for such cases native tables are not powerful
enough. It was created for the specific project demands and grew quite
powerful.
There are currently efforts under way to refactor the code and build an
even more powerful, clearly structured table control.

Lorenz Maierhofer

The SWT Table is based on native table controls which are not intended to
act like a spread sheet. Currently, there is no support in Table for things
like merging cells or spilling over into adjacent cells.

Having a pop down appear is quite simple to implement. See:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet124.java?rev=HEAD& amp;content-type=text/vnd.viewcvs-markup

Note in the example above that the table editor can be any widget - e.g.
combo box. Also you can add a listener to the text widget and open a list
when the text matches a value.
