IDLWAVE understands the difference between procedures and functions.
You are trying to complete a procedure, whereas DIALOG_PICKFILE is a
function, so it doesn't show up in the list. Try:
f=dia[M-Tab]
and DIALOG_PICKFILE should show up. IDLWAVE actually understands the
completion context of many different things. The current list is (for
point at the `_'):
plo_ Procedure
x = a_ Function
plot,xra_ Keyword of plot procedure
plot,x,y,/x_ Keyword of plot procedure
plot,min(_ Keyword of min function
obj -> a_ Object method (procedure)
a[2,3] = obj -> a_ Object method (function)
x = obj_new('IDL_ Class name
x = obj_new('MyCl',a_ Keyword to Init method in class MyCl
pro A_ Class name
pro _ Fill in Class:: of first method in this file
!v_ System variable
!version.t_ Structure tag of system variable
self.g_ Class structure tag in methods
state.w_ Structure tag, if tag completion enabled
name = 'a_ File name (default inside quotes)
You can also force the IDLWAVE completion context, e.g. using the menu
IDLWAVE->Complete->Complete Specific. Of course, if you complete
DIALOG_PICKFILE as a function but call it as a procedure, IDL will
complain and it won't work. Usually IDLWAVE knows best.
