Hi -
I've got my J 8.03 simple GUI window basically working - all it does is get
an input and output file. The ten lines of code that do the work in which
I'm interested are dwarfed by the 90 or so lines of GUI code.
However, I still don't understand how to update a message area as I proceed.
Right now, the code invoked by my "Done" button looks like this:
iofiles_doneBtn_button=: 3 : 0
inpfl_Input_=. inpfl_Input_-.LF
if. '/'={:outpfl_Input_ do.
wd 'set msgBox text Please set output file'
wd 'set outpfl focus'
else.
if. fexist outpfl_Input_ do.
wd 'set msgBox text Overwriting ',outpfl_Input_
end.
rc=. 1
wd 'set msgBox text Starting at ',(":(6!:0)''),'...'
wd 'set doneBtn focus'
try. denormalize_base_ inpfl_Input_;outpfl_Input_
catch. rc=. 0 [ wd 'set msgBox text Error' end.
(6!:3) 2 [ wd 'set msgBox text Done at ',(":(6!:0)''),'...'
if. rc do. wd 'set msgBox text Tabular output in
"',outpfl_Input_,'"' end.
smoutput (6!:0)''
ioFiles_close ''
end.
''
)
As you may be able to guess from looking at this, I want to update the
message area with a warning that I'm overwriting an existing file if that's
the case, and I want to put some kind of confirmation when I'm done.
However these parts do not do anything. I understand that the latter part
of the code does not work whereas the initial request to "Please set output
file" does because the initial message exits, giving control back to the
event loop whereas the other messages don't get a chance to be displayed
because I'm still in the "Done" button routine.
So, any ideas how one handles this sort of thing (showing messages while
continuing other processing)? Do I need to mess with the system timer or
something?
Thanks,
Devon
