Material Names as array for dropdown box

[j-man]

Hi Bronson,

You need to build a new array of materials by querying the materials names from your material array in a for loop

mymat.name

ok ive got the following



myMaterialListName = #("Material #25", "Material #25")
dropdownlist myMaterialName width:80 height:40 pos:[5,245] items:myMaterialListName

but they dont show in the list, also ill need to be able to update the list, i tryed the following.

dropdownlist.mymaterialname.items

but it doesnt allow me to update them.

EDIT: ok ive noticed it doesnt work the first time i load the script, but the scond time i load it it works as the array is in memory. So basically i need to get the dropdownlistbox to update... How do i do that?


Thanks

ok,

So you need to build you list of strings when the rollout opens. So define a function that builds the list, and then call it when the rollout opens:


rollout myrollout "rollout"
(
fn collectmatnames=
(
...collect material names...
mydropdownlist.items=blahblah
)
on myrollout opens do collectmatnames()
)


You can then call this whenever the list might change (ie new materials added, etc)

ok when i use the following

dropdownlist myMaterialName "" width:80 height:40 pos:[5,245]
myMaterialName.items=myMaterialListName

i get the following error

>> MAXScript Rollout Handler Exception: -- Unknown property: "items" in undefined <<

Basically it seems as tho its not able to use the .items part :|

[j-man]

Are you tring to change the items from outside the rollout? if so you will need to specify the rollout:

myrollout.myuidropdownlist.items

Oh, and my code above should read open, not opens.

If this doesn't help, maybe you should post some more code to look at.

Josh.

Cool, that works well!

just need the extra myrollout. bit on there.

I was doing it from within a function.
