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:


	@@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.


@@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.
