Hi Jeff,<br>
<br>
I wanted to further explain the performance issue with having text
windows in<br>
each cell. Tktable is very fast in creating a large table populated by
text widgets.<br>
The performance issue is with the resizing of rows and columns. When<br>
resizing a row for example Tktable is updating the table with each
motion of the mouse.<br>
It would be a great feature if it could update the table only after
button 1 has been<br>
released. Only, the title column or title row would be resized with
each motion of the<br>
mouse. A resize "bar" could be displayed to also indicate where the row
or column<br>
will be resized. For example, this is how resizing is performed in MS
Excel which<br>
makes resizing large tables feasible. Another example is the -jump
option for<br>
scrollbars (btw, -jump doesn't work in the Windows platform).<br>
<br>
Thanks,<br>
<br>

What can't you already do through the global bindings and the
commands that tell you the current cell?

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).
