Follow-up Comment #12, bug #53046 (project octave):

Oh, I see what you mean now.  If it is 3-d matrices or greater, or perhaps
even something that can't be displayed in a table, the contents of that
variable widget is just the text output...that presumably can't be edited, but
will update accordingly.  Updating with internal changes is probably the way
it should be.  (This feature was part of the code I didn't understand, i.e., a
QTextEdit in the mix...I'll recheck this.)

I've pulled the latest development code, but I'm not seeing this.  For

x = rand  (10,20,30)

all I see is a blank gray window with a tab labeled "x".  If I then change to

x = rand (10,20)

I see the QTableView/spreadsheet view.

I'm compiling version 981990aaa93191849f64a811853d6cca529cc6db which is the
parent of my changeset and... nothing.  I could paste a screenshot if you
like, but there isn't much to see but a blank window.  I've turned off pager
and tried a few things, but I can see anything.

The copy/paste, yeah, it's using ASCII transference of data.  I know this
because this is at least one thing I fixed.  One issue was an extra CR at the
end that was interpretted as N + 1 elements when copying N elements and then
pasting into N elements.  That ASCII choice was probably the simplest means
of, say, pasting into an external spreadsheet.  Clipboarding isn't the easiest
thing.  I've programmed some X clipboards, which is superflexible, but tricky.
 (Have to ping the receiving/sending application for the data formats it
accepts and which is the preferred format.  Then hopefully one can supply that
format.)  I would think that Qt has added some kind of feature that will take
data from a model and copy to/from clipboard.
