Thread Subject: uitable on cell array containing strings

Recently I have great frustration using the "undocumented"
uitable functionality. Although it works fine with numerical
matrix, it doesn't work with cell array, e.g.,

Matlab command
t = uitable({'a', 'b'}, {'col_1', 'col_2'})
behaves as expected. It creates a table with 2 columns and
two table entries.

However, subsequently:
set(t, 'Data', {'c', 'd'})
generates an error: "??? Object belongs to an incompatible
Java class."

Could someone shine some light on this? Thank you,

Well, I figured out myself. Remembering what Yair said last
time, I dig into the code, and found that I have to use
"t.setData()" instead of "set" to update the table content.

This undocumented feature is very difficult to use and its interface will
probably change soon when it becomes documented. function. You get an error
because t is a java handle and not a regular HG handle.

Try this:
>>t = uitable({'a', 'b'}, {'col_1', 'col_2'})
>>t.setData({'c', 'd'})

You can look at some usage examples in this application:

Stuart,

Thank you very much! That helps a lot. I can't wait for the
"documented" uitable because I have to finish the GUI fast
(after all, that's why people use Matlab in the first
place). I just wish them put the feature in asap.

uitable becomes documented in the upcoming Matlab version
(R2008a, aka 7.6), at least in the beta version. I have
still not investigated the degree to which it became
documented with respect to the underlying Java functionality.

Hello,
i try to update a uitable which contains a basic matrix of
numbers. How can i do it (using the setData i suppose)?
typically, my table t contains matrix Datatable, and i want
to update the table with a new matrix Datatable_updated.
the basic command t.setData(Datable_updated) doesn't work.
What is the syntax when you want to update a table?
thanks

Thierry,

Did you find a solution to this problem? I have the same issue trying to set an array. I can not upgrade to take advantage of the documented version due to project requirements.
