Ah, sorry! I misread your mail. I saw
'(if ...
'(cond
So I thought '(if ...) is the button action, and thus the cond expression quoted
again :)
So yes, (cond ..) is the button action, also in the code in app/item.l:
(gui '(+Drop +Button) '(field -1)
'(if (: home obj jpg) ,"Uninstall" ,"Install")
'(cond
((: home obj jpg)
(ask ,"Uninstall Picture?"
(put!> (: home top 1 obj) 'jpg NIL) ) )
((: drop) (blob! (: home obj) 'jpg @)) ) )
This button changes both title and behavior, depending on whether (: home obj)
already has a 'jpg' prooperty or not.
*If* (: home obj jpg) is there, it uninstalls the image.
Otherwise, if something was dropped on the button, the path is in the (: drop)
property, and stored as a blob in the item.
You could try to debug it. Put a breakpoint
((: drop) (! blob! (: home obj) 'jpg @))
Then put an image into the upload field and press the button (or drag/drop an
image onto the button if your desktop and browser support it).
It will stop at the breakpoint
(blob! ...
Then look at
! (: drop)
As ever, you need to start in debug mode (recommeded anyway) with a '+' at the
end of your command line.
