fail to change width of a dropdown Control

Grischu · 05/01/14, 11:54 AM

I create a dropdown controll and try to create it with this code

validChoices= BB.CharacterListe()
local dropdown = WINDOW_MANAGER:CreateControlFromVirtual(controlName.."ToonName", LeftFrame, "ZO_Options_Dropdown")
BB.dropdown=dropdown
dropdown:ClearAnchors()
dropdown:SetAnchor(TOP, toonlabel, BOTTOM, 0, 1)
dropdown:SetHidden(false)
dropdown.text = "Toon"
dropdown.valid = validChoices

local dropmenu = ZO_ComboBox_ObjectFromContainer(GetControl(dropdown, "Dropdown"))
ZO_PreHookHandler(dropmenu.m_selectedItemText, "OnTextChanged", function(self)
if dropmenu.m_selectedItemData then
selectedName = dropmenu.m_selectedItemData.name
dropmenu.m_selectedItemText.SetText(self, selectedName)
BB.SetToon(selectedName)
end
end)
dropdown:SetHandler("OnShow", function()
dropmenu:SetSelectedItem(validChoices)
end)

local function OnItemSelect(_, name, choice)
BB.SetToon(name)
end

for i=1,#validChoices do
local entry = dropmenu:CreateItemEntry(validChoices[i], OnItemSelect)
dropmenu:AddItem(entry)
end

i tried it with

dropdown.SetWidth(100)

or

local childs = dropdown.GetChildren()
for x, obj in pairs(childs) do
obj.SetWidth(100)
end

the last one raises a error, the other one has no effect.

Can anyone help me out, please.

Most control functions expect the object as first parameter.

So either
obj.SetWidth(obj, 100)
or
obj:SetWidth(100)

The template you are using, "ZO_Options_Dropdown" is not the dropdown control itself. It is a wrapper control that contains a label and a dropdown box laid out horizontally.

You need to get the actual dropdown control from your wrapper control.

I suggest you use "/zgoo mycontrolname" to look through the children of the wrapper control and figure out exactly what you need to extract.

Also, as a side-note you should probably use ZO_ComboBox instead since it doesn't have the unnecessary label, but I still think you'd need to extract the dropdown from it in the same way.
