Hi
Problem with multilistbox
(
local MYObjs = #()
rollout multi "" height:245 width:140
(
multiListBox lbx_Obj "Objects list" pos:[10,7] width:120 height:12
button Add_Obj "Add" pos:[10,185] width:24 height:24
button sel_lis "sel" pos:[34,185] width:24 height:24
button Mov_Up_lis "^" pos:[82,185] width:24 height:24
button Mov_Dw_lis "v" pos:[106,185] width:24 height:24
--add objects to the multiListBox
on Add_Obj pressed do
(
userSel = getCurrentSelection()
if userSel.count >= 1 do
(
for o in userSel do (appendIfUnique MYObjs o)
lbx_Obj.items = for i in MYObjs collect i.name -- update list with array
)
)
--select all scene objects in multilistbox items
on lbx_Obj selected lis do
(
itemsel = for j in lbx_Obj.selection collect getnodebyname lbx_Obj.items[j]
select itemsel
)
on Mov_Up_lis pressed do
(
local itm = lbx_Obj.selection as array
swap lbx_Obj.items[itm] lbx_Obj.items[itm-1]
lbx_Obj.items = lbx_Obj.items
swap AnimObjs[itm] AnimObjs[itm-1]
lbx_Obj.selection -= 1
)
on Mov_Dw_lis pressed do
(
local itm = lbx_Obj.selection
if itm < lbx_Obj.items.count do
(
swap lbx_Obj.items[itm] lbx_Obj.items[itm+1]
lbx_Obj.items = lbx_Obj.items
swap MYObjs[itm] MYObjs[itm+1]
lbx_Obj.selection += 1
)
)
)
createDialog multi
)
1_we adds some objects to the multilistbox list, is it possible by a button or function when we select the objects in the scene the objects get selected in the multilistbox list?
2_can anyone help me with the shifting the multi listbox items
Thanks in advance

It needs optimizations.
Thanks so much Jorge
I’ve never could do this with my awful scripting
Thanks again man
I’d say in addition to loading the callback on opening the rollout, try to unregister it first. I know you doing it on the close, but this will be a fail safe. You can even list the current callbacks in the scene on opening the rollout then unregister if found.
In the previous sample script the Callback is being unregistered on both Open and Close events, or are you suggesting something different?
Additionally, while it might be a good practice, from my experience I don’t find it is really necessary to check if a given Callback already exist in order to remove it, as removeScripts() won’t throw any exception if the Callback doesn’t exist.
