I’ve got 2 dropdown lists and list 1 will populate list 2 depending on the selection made.
I need to create an output path from the combined selections but I can’t figure out how to read the selection from the second list due to the array
The code I am using is;
array_1= #()
array_1[1] = "item 1"
array_1[2] = "item 2"
array_1[3] = "item 3"
array_2= #()
array_2[1] = "item 2-1"
array_2[2] = "item 2-2"
array_2[3] = "item 2-3"
try (destroyDialog Asset_Rollout) catch()
rollout Asset_Rollout “Asset” width:400 height:300
(
dropdownlist _dd1 “list_1” width:290 pos:[38,50] items:array_1
dropdownlist _dd2 “” items:blank width:300 pos:[38,100] visible:on
dropdownlist _dd3 “” items:array_2 width:300 pos:[25,100] visible:off
dropdownlist _dd4 “” items:array_2 width:300 pos:[25,100] visible:off
local rolls = #(
#(_dd2),
#(_dd3),
#(_dd4)
)
on _dd1 selected sel do
(
for k=1 to rolls.count do for c in rolls[k] do c.visible = (k == sel)
)
AssetMaxFileOut = _dd1.selected + @”/” + rolls.selected + “.max” –not working due to rolls.selected
print AssetMaxFileOut
)
createdialog Asset_Rollout
How can I get the selection from the 2nd dropdownlist and output that selection?
Ive commented out the last two lines that don’t work due to rolls.selected
Thank you for any help
you could use a function to get the current visible rollout in the rolls array
something like:
fn getVisibleItem rolls =
(
for roll in rolls do (
for item in roll do (
if item.visible then return item
)
)
undefined
)
or you could save a reference to the current visible drop down from the event handler for _dd1
but I think the cleanest way to go here is to have only one drop down list for the 2nd list and switch the items. something like this:
(
try (destroyDialog Asset_Rollout) catch()
rollout Asset_Rollout "Asset"
(
local array_1 = #("item 1", "item 2", "item 3")
local array_2 = #("item 1-1", "item 1-2", "item 1-3")
local array_3 = #("item 2-1", "item 2-2", "item 2-3")
local array_4 = #("item 3-1", "item 3-2", "item 3-3")
local arrays = #(array_2, array_3, array_4)
dropdownlist _dd1 "list_1" items:array_1
dropdownlist _dd2 "" items:array_2
on _dd1 selected arg do
(
_dd2.items = arrays[arg]
)
on _dd2 selected arg do
(
local AssetMaxFileOut = _dd1.selected + "\\" + _dd2.selected + ".max"
print AssetMaxFileOut
)
)
CreateDialog Asset_Rollout
)
Matan, the second option you gave is exactly what I was trying to achieve. Thank You for your help.
