Hi Shawn,<br>
<br>
I understand your suggestion, however, I don't want to remove the text
widget. I want all the cells contents visible<br>
to the user at all times. The user needs to have control over font
size, foreground and background colors and not<br>
just on the whole text widget. They need to have the ability to make
these change on individual characters within<br>
each widget. As far as I know the only way to do this is to use the
text widget. The only downside is a performance<br>
loss when resizing rows and columns for large tables.<br>
<br>
Thanks for the suggestion,<br>
<br>

might be to create an embedded text widget in the active cell that has
a unique tag to which all the cell specific bindings are bound - this
gives a place to write the bindings that are unique to the table
cells. Destroy the embedded widget - and create another when the
active cell changes. -- The appearance is of all the cells being
bound. It's a fair bit of work to get excel like tables, and bec

more interesting as you look at cell or row/column multi-selection and
cut and paste functionality -- and cross platform behavior issues,

improvement over creating an embedded text widget in every cell.. </span> </font></div>

I do see your point. I was thinking that you needed to have a binding
for each cell. However,<br>
I think I can accomplish what I want through a global binding and the
commands you mention.<br>

It may be great, but you are just better off embedded a text
widget there if you really need one. That's a huge effort
that I don't see ever being done due to the complexity
involved (when just embedding a widget works too).

I tried the text widget in each cell and it does have an effect on
performance. The other<br>
downside (which may have a workaround) is when you select a region of
cells when<br>
-selectionmode extended there's no indication that the cells are in a
selected region<br>
(background color doesn't change). I have to admit that I didn't play
around with all the<br>
options available to see if I can't get this to work. Is there a way to
have the text widget<br>
not cover up the column and row separators? Also, is there a way to
have the column and<br>
row separators turn a darker color (highlighted) when they are selected?<br>
<br>
Basically, my overall goal is to duplicate some of the basic features
that MS Excel has. For example,<br>
the way a region of cells appears when they are selected, double
clicking in order to edit a cell etc...<br>
<br>
Thanks for you help,<br>
