Table Index

[Slimwaffle]

I am having trouble with some code and could use some help. I want to say table index = to choice box selected. 

  mitem.icount is the table and GameMenu.materials is the choice box.

This was the code I used but it keep showing a nil value.      

mitem.icount = GameMenu.materials:GetSelectedItem()
 

Its for a trash materials button. I want to be able to say table index is = to table index -1 then return the value.

Not sure if i follow exactly what you are asking for, but here is a simple example of a listbox and a button. When the button is pressed, it will delete the selected item from the table used to create the items in the listbox.

local window = Window:Create("example",0,0,400,300,Window.Titlebar+Window.Center)
local context = Context:Create(window)
local gui = GUI:Create(context)
local base = gui:GetBase()
base:SetScript("Scripts/GUI/Panel.lua")

mitem ={}
table.insert(mitem,"Wood")
table.insert(mitem,"Steel")
table.insert(mitem,"Concrete")
table.insert(mitem,"Rubber")
table.sort(mitem)

button1 = Widget:Button("Delete",240,20,100,40,base)
listbox1 = Widget:ListBox(20,20,200,100,base)

function AddStuffToList(mytable,widget)
	widget:ClearItems()
	System:Print(#mytable)
	if #mytable > 0 then 
		for n = 1, #mytable do
			widget:AddItem(mitem[n], n==1)
		end
	end
	widget:Redraw()
end
AddStuffToList(mitem,listbox1)

while not window:KeyHit(Key.Escape) do
	if window:Closed() then return false end
        
	while EventQueue:Peek() do
		local event = EventQueue:Wait()
		if event.source == button1 then
			if listbox1:GetSelectedItem()~=-1 then
				table.remove(mitem,listbox1:GetSelectedItem()+1)
				AddStuffToList(mitem,listbox1)
			end             
		end
	end
	context:Sync()
end

I figured this out it was actually easier then I thought. Now my issue is getting the choice box to redraw the text. Using the redraw command is not working and using SetText doesn't work either. But here is the code I used to fix it.

i = GameMenu.materials:GetSelectedItem()
        mitem.icount = mitem.icount -1
        System:Print(mitem)
        System:Print(mitem.icount)

I am trying to design my inventory so everything is shown on the choice box
