Ric,
Thank you again for your most informative response.
I had no idea that the left argument enabled cell editting
and now was pleased to "discover" that such a simple
one-line entry could permit cell editting by just clicking
on a cell and then editting it. I assumed a more complete
script like the demo's you pointed to later was required
before cell editting could be done.
The jwiki pages and demos you give are most
valuable. I noticed in the demos that I was unable to close
the grids with my escape key. So I experimented a little
and added a line to the griddemo2 and griddemo3 as follows.
This is handy for folks who use keys when possible to avoid
mouse clicks.
griddemo2:
gdemo_cancel=: destroy
griddemo3:
gmain_cancel=: destroy
I wish J _close also honored the keychord for _close
like the J IDE does, but when I include lines like the
following I cannot close a control with the system keychord.
Is this a Mac feature or do other platforms work similarly?
If so, perhaps enabling this could be added in future J
releases.
gdemo_close=: destroy
gmain_close=: destroy
