i creat a form with an report field. The value in the header should not a fixed value in the code, it should be a varialbe.
but i get an error, fixnum req.
here is the code
width = 30x ( some digit)
reportField = hiCreateReportField( ?name 'reportField ?title "Report" ?selectMode 'multiple ?headers '( ("obj-type" 75 'left) ("l" 75 'left) ("pp" 75 'left) ("description" width 'left) ) ?choices ch)
if i change with to e.g. 100 , everything is fine.
If you use '(...) the list is quoted which means that nothing is evaluated inside the list. You have a couple of choices:
?headers list( list("obj-type" 75 'left) list("l" 75 'left) list("pp" 75 'left) list("description" width 'left) )
Or you could use the backquote approach which allows selective evaluation of things preceded by a comma (note the 'left will be quoted - so don't really need the quote either):
?headers `( ("obj-type" 75 left) ("l" 75 left) ("pp" 75 left) ("description" ,width left) )
Sometimes the backquote approach is cleaner because it is clearer when you are just inserting a small number of values into an otherwise static list structure. It's actually a macro which expands into list() (and other function calls).
In reply to Andrew Beckett:
Hi Andrew, I mostly have similar problem but I am trying to update a variable value into choices? but not on headers?
I am finding your syntax (one of the above mentioned choice) matches to my syntax as below, but when I execute the code width variable box remains empty on the form.
Should I refresh page or something, Please help me get this right?
I have also created a post regarding this I would remove it if I find answer here. Thanks.
?choices list( list("obj-type" 75 ) list("l" 75 ) list("pp" 75 ) list("description" width ) )
