How to get programmatic access to a control defined in XML

With the friendly help I've received on this forum I've succeeded in putting a scene fragment on the Guild Home screen:

Code:

<GuiXml>

  <Controls>

    <TopLevelControl name="MyFragment" hidden="true">

      <Dimensions x="200" y="200" />

      <Anchor point="BOTTOM" relativeTo="ZO_GuildSharedInfo" relativePoint="BOTTOM" offsetX="120" offsetY="680" />

      <Controls>

        <Label name="$(parent)Label" width="200" height="25" font="ZoFontWinH3" inheritAlpha="true"  color="FFFFFF"

            wrapMode="TRUNCATE" verticalAlignment="TOP" horizontalAlignment="CENTER"  text="some text">

          <Anchor point="TOP" relativeTo="$(parent)" relativePoint="TOP" />

        </Label>

      </Controls>

    </TopLevelControl>

  </Controls>

</GuiXml>

Lua Code:

local fragment = ZO_SimpleSceneFragment:New(MyFragment)
GUILD_HOME_SCENE:AddFragment(fragment)

Now I want to change the text of the label control MyFragmentLabel under program control but I can't work out how to get a reference to it.

That's one of the easier things to do:

Lua Code:

local label
label = MyFragmentLabel
-- or --
label = MyFragment:GetNamedChild("Label")
-- or --
label = GetControl(fragment.control, "Label")
label:SetText("Hello World!")

You named your label control "Label" and it is a child of your "MyFragment" control, so you can just access it via its global variable or relative to the control.

Thanks, it turns out I was doing the right thing but my error was elsewhere. Knowing that what I was doing really ought to work was the fixed point in the reasoning that I needed.
