How to update a ComboBox database list?

Phinix · 05/07/15, 04:57 PM

I have a ComboBox dropdown menu that is populated by a database of character names.

I have a function that removed the selected character name from the database and re-selects the currently logged in character.

The problem is, I want to remove that name from the drop down list when this function files.

I have tried GetItems() UpdateItems() and others to no avail.

Does anyone know how to update the list?

I used this to populate it:

Code:

	for k, v in pairs(nameList) do
		local entry = charnameDropdown.dropdown:CreateItemEntry(v, OnItemSelect)
		charnameDropdown.dropdown:AddItem(entry)
	end

I can't seem to find a RemoveItem() function...

It seems if I can re-initialize the main control I can just rebuild it. I'm not sure how to "delete" a control though.

Can I just set it to nil and re-run my initialization function? Testing...

EDIT: Yeah... no. That didn't work. "Duplicate name" still exists.

I think you just need to NIL the entry that you want to delete.
Or clear the list and rebuild it without the entry.
I couldn't find any remove function neither.

Here is the initialization function:

Code:

local function SetupCharacterDropbox()
	currentChar = GetUnitName("player")
	table.insert(nameList, 1, currentChar)
	for i = 1, 486, 1 do
		if next(MRL.AccountSavedVariables[i].names) ~= nil then
			for n = 1, #MRL.AccountSavedVariables[i].names, 1 do
				local name = MRL.AccountSavedVariables[i].names[n]
				if not Contains(nameList, name) then
					table.insert(nameList, #nameList + 1, name)
				end
			end
		end
	end
	charnameDropdown = WINDOW_MANAGER:CreateControlFromVirtual("CharacterDropdownList", MainFrameListFrameBatchTracking, "ZO_StatsDropdownRow")
    charnameDropdown:SetWidth(300)
    charnameDropdown:SetAnchor(TOPLEFT, MainFrameListFrameBatchTracking, TOPLEFT, -4, 2)
    charnameDropdown:GetNamedChild("Dropdown"):SetWidth(295)
    charnameDropdown.dropdown:SetSelectedItem(currentChar)
    local function OnItemSelect(_, charName, choice)
        currentChar = charName
    end
    for k, v in pairs(nameList) do
        local entry = charnameDropdown.dropdown:CreateItemEntry(v, OnItemSelect)
        charnameDropdown.dropdown:AddItem(entry)
    end
end

Setting charnameDropdown to nil still results in "duplicate name" if I re-run the function. Just rebuilding the list the last part results in duplicate items in the list.

You need to use the clear function on the combobox so it gets cleared. If you set it to nil it maybe remmeber the combobox entries somehow?

btw why do you need to loop 486 entries o0

Tried charnameDropdown.dropdown:ClearItems() followed by setting it to nil...

Still get: control 'CharacterDropdownList'. Duplicate name.

I am looping through 486 entries because there are 486 recipes in the game. I have a global tracking system that adds character names to a table for each when they learn a recipe (also check for updates at login).

It is actually faster than having a table of 486 entries created for each character.

Figured it out...

Code:

	
	currentChar = GetUnitName("player")
	charnameDropdown.dropdown:ClearItems()
	for k, v in pairs(nameList) do
		local entry = charnameDropdown.dropdown:CreateItemEntry(v, OnItemSelect)
		charnameDropdown.dropdown:AddItem(entry)
	end
	charnameDropdown.dropdown:SetSelectedItem(currentChar)

Moved OnItemSelect out of the initialization loop so I could call it elsewhere.
