Remove multilisbox selections

[davestewart]

btw, how is it possible to put 2 fn in one?


I odn't think so, I tried the exact same thing the other day, and only one function was created. Easiest thinfg is to use 2 intermediate functions that call the main function.


For multilistboxes, the selection is a bit-array (NOT an index) in your case elements 5 to 11 are selected, so you would need to loop BACKWARDS through your array (from 11 to 5), calling deleteItem on it, then re-apply the items to the multilistbox.

If you don't go backwards, you count up from 5 to 11, but by the time you're halfway through deleting items (5, 6, 7, 8), you've already shortened the array below, say 8, so iterations 8 and above would fail, as you can't delete element 8, 9, 10, or 11 as the array is already too short.

Make sense?

thx for your answer.

i m going to try it ;)

I'm back again :P
I just continue my script and fund the answer about how to use 2 functions in 1

the original functions are:


fn PathfilterUnique obj = findItem PathNameArr obj.name == 0
fn ShapeSelectionLimit = shape_filt obj = isKindOf obj shape

and the answer is:

fn PathfilterUnique obj = ((findItem PathNameArr obj.name == 0) and ( isKindOf obj shape))

about the question; how to delete my Mlb selection; a friend fund this;

on parentDelBtn pressed do
(
index=parentRollout.parentLbx.items.count
while index > 0 do
(
temp = parentRollout.parentLbx.items
if parentRollout.parentLbx.selection[index] == true then
(
deleteItem temp index
parentRollout.parentLbx.items = temp
)
index-=1
)
)

:D

I hope it can help some people.

Here's another way that's a little more optimized


-- list is the multiListBox

on bt_remove pressed do
(
items = (list.items as array)
for o = (list.items as array).count to 1 by -1 where ( findItem (list.selection as array) o ) != 0 do deleteItem items o
list.items = items
)

thx for your answer Jason ^^

Sorry for replying way after the fact :)

Or even shorter ;)
list.items = for i = 1 to list.items.count where not list.selection[i] collect list.items[i]

Oh snapple!

Oh snapple!

list.items = for i in (-list.selection) collect list.items[i]

*cough*

[holycause]

pfffff

echt bedankt

[magicm]

Haha nice one Richard. Should have thought of that
Idea for the next mxs challenge? Write a script that does ... with as little code as possible

Oh snapple!

I've been actually in a Fanta mood lately, but saying 'Oh Fanta' doesn't roll off the toungue!
