Help with dialog

[Pixero]

I need to make a dialog with three dropdown menus where the user can choose from the scenes materials and one input where the default value would be say 1000 mm.

I have looked at other scripts and tried to create it but I've messed up somewhere as I haven't done my menus in the exact same way as the examples. Could someone please guide me to a working solution?
Here is the Dialog part of the script:

Code: Select all

   @@first_mat = nil
   @@second_mat = nil
   @@third_mat = nil
   @@distance = nil

   model = Sketchup.active_model 
   mats = model.materials
   ent = model.entities 
   sel = model.selection 
   
   matNames=[]
   matNstmp=[]
   mats.each{|m|matNstmp.push(m.display_name)}
   matNstmp.sort!
   matNames=matNames+matNstmp
   matList=matNames.join('|')
   
   @@first_mat = matList unless @@first_mat
   @@second_mat = matList unless @@second_mat
   @@third_mat = matList unless @@third_mat    
   @@distance = 1000.mm unless @@distance   
   
   # dialogs
   info = [matList]
       prompts = ["Material 1: ", "Material 2: ", "Material 3: ", "Distance: "]
       results = inputbox(prompts,["", "", "", 1000.mm], [matList, matList, matList, nil],"Settings")
   results = nil if results and results[0] == ""

Use this:
@@first_mat = matNames[0] unless @@first_mat
@@second_mat = matNames[0] unless @@second_mat
@@third_mat = matNames[0] unless @@third_mat
@@distance = 1000.mm unless @@distance

Then use those in your inputbox's default values etc...
prompts = ["Material 1: ", "Material 2: ", "Material 3: ", "Distance: "]
defaults = [@@first_mat, @@second_mat, @@third_mat, @@distance]
pops = [matList, matList, matList, ""]
title = "Settings"
results = inputbox(prompts, defaults, pops, title)

After a successful 'result' is returned you need to reset the remembered 'values', thus:
@@first_mat, @@second_mat, @@third_mat, @@distance = results ###if results

Thank you!

And another one:


See how the dropdown menu looks in the attached image.
I have used drop down menus in scripts before without problem but can't find whats wrong here.

Code: Select all

@@axis = "Y" unless @@axis
prompts = ["Axis: "]
drops = ["X" '|' "-X" '|' "Y" '|' "-Y" '|' "Z" '|' "-Z"]   
title = "Settings"
defaults = @@axis
results = inputbox(prompts, drops, title, defaults)

It should be
results = inputbox(prompts, defaults, drops, title)
You have the wrong order... 'defaults' comes second in the list that is passed to the inputbox, AND it must be made as an array - so use defaults = [@@axis] assuming that @@axis is a string- e.g. "X" etc...

Thanks. That worked.
