CreateControlFromVirtual -- help

[NickK]

Once again i need help. I'm trying to dynamically create labels and so far nothing i tried worked. I read the part "Is there a way to dynamically create controls like buttons or labels?" on Addon Quick Questions on wiki but i can't figure out what i am doing wrong.

First i copy/pasted the xml from the wiki and i removed the button while changing the name of the label and adding virtual = "true", but i was getting the error "CreateControlFromVirtual Failed". After messing around and trying different things (while still getting the failed message) i decided to copy paste and use what wiki had as is, without changing anything, only to find out that i was getting the same error again.

This is the xml (same as wiki):

<Button name="DynamicButton" virtual="true" text="Click">
    <Controls>
        <Label name="$(parent)InnerLabel" text="Label" font="ZoFontGame">
            <AnchorFill/>
        </Label>
    </Controls>
</Button>

And this is the lua:

function OnLoad(eventCode, name)
for i = 1, 10 do
    local dynamicControl = CreateControlFromVirtual("DynamicButton", ZO_FriendsListList, "DynamicButton", i)
end
 
DynamicButton2:SetText("2")
 
 
end

The only difference is that i added a TopLevelControl which is the ZO_FriendsListList.

What am i doing wrong here?

I also checked around in the forum and i found that Wykkyd managed to create a dynamicly dropdown menu using WINDOW_MANAGER only, i tried to do it with WINDOW_MANAGER as well but it didn't work ether.

Thanks for your help.

Well, your button template does not have a size, for starters. It also doesn't have a texture, if you wanted it to look like anything.

Buttons don't need textures if they have text. For a long time, Grid View used a text-only button until I got around to changing it to an icon.

Hi, had same issue with my own dynamically created buttons. Found from Zgoo that "i" was not being appended to the name how it was supposed to from wiki, so buttons were all "DynamicButton". Found I had to do: (obviously without the "ZO_FriendsListList" bit!)

for i = 1, 10 do
    local dynamicControl = CreateControlFromVirtual("DynamicButton" .. i, ZO_FriendsListList, "DynamicButton", i)
end

(also the "i" at the end could be omitted, seemed to do nothing!)
Buttons were then created with no errors and with differing names as they were supposed to.

Also I found that "DynamicButton2:SetText("2")" didn't change the label I had on the button. Changing the XML; removing the label part fixed it.

<Button name="DynamicButton" virtual="true" text="Click">
</Button>

Hope any of that helps.

Suffix is defined in global function CreateControlFromVirtual(...), so if you use this function it works just fine.
Please do not confuse that function with WINDOW_MANAGER:CreateControlFromVirtual(...).


EDIT: As to the original question I'd try to use default template instead of custom (this code works for me):

for i, row in pairs(ZO_FriendsListList.activeControls) do
   local button = CreateControlFromVirtual("DynamicButton", ZO_FriendsListList, "ZO_DefaultTextButton", i)
   button:SetAnchor(RIGHT, row, LEFT, 50, 0)
   button:SetText(tostring(i))
end
