fontString:SetFont()

I have an object from game to which I assign text:

Code:

object:SetText("my text")

I can also assign a font to it right away:

Code:

object:SetFont(My_Font, size)

But some objects don't allow me to assign a font so explicitly:

Quote:

attempt to call method "SetFont" (a nill value)

The object receives, for example, the function:

Code:

for _,GTxtframe in GossipFrame.GreetingPanel.ScrollBox:EnumerateFrames() do

How to specify the exact name of the fontString element of object?

Here's the code snippet I'm having problems with:

Code:

      for _,GTxtframe in GossipFrame.GreetingPanel.ScrollBox:EnumerateFrames() do

        if (GTxtframe.GreetingText) then    -- Greeting Text

            GTxtframe.GreetingText:SetText(Greeting_PL);

            GTxtframe.GreetingText:SetFont(QTR_Font2, 13);

        elseif (GTxtframe.GetElementData().buttonType==3) then  -- Options

            GTxtframe:SetText(GS_Gossip[OptHash]);

            GTxtframe:SetFont(QTR_Font2, 13);    -- ERROR: attempt to call method "SetFont" (a nill value)

        end

      end

It's similar here:

Code:

      for GText in QuestFrameGreetingPanel.titleButtonPool:EnumerateActive() do

          GText:SetText(prefix .. GS_Gossip[TitleHash] .. sufix);

          GText:SetFont(QTR_Font2, 13);        -- ERROR: attempt to call method "SetFont" (a nill value)

      end

That's because the widget type you're "getting" is a Button. Buttons don't have a SetText or Setfont method by default but in some case they are "given" a SetText method to update a FontString they have also been given.

Lua Code:

local Button = CreateFrame("Button", "SomeButton", UIParent)
Button.Text = Button:CreateFontString(GameFontNormal)
Button.Text:SetPoint("CENTER")
function Button:SetText(text)
    self.Text:SetText(text)
end

You can

Code:

Button:SetText("Something")

but you can't

Code:

Button:SetFont(SomeFont)

but you could

Code:

Button.Text:SetFont(SomeFont)

In this case, you need to find the FontString "sub-widget" of GTxtframe you want to effect (like .GreetingText, it may be something other than .Text).

Taking a look at the templates you could probably use:

Lua Code:

for _,GTxtframe in GossipFrame.GreetingPanel.ScrollBox:EnumerateFrames() do
    if (GTxtframe.GreetingText) then    -- Greeting Text
        GTxtframe.GreetingText:SetText(Greeting_PL);
        GTxtframe.GreetingText:SetFont(QTR_Font2, 13);
    elseif (GTxtframe.GetElementData().buttonType==GOSSIP_BUTTON_TYPE_OPTION) then   -- Options
        GTxtframe:SetText(GS_Gossip[OptHash]);
        local regions = { GTxtframe:GetRegions() }
        for k, v in pairs(regions) do
            if v:GetObjectType() == "FontString" then
                v:SetFont(QTR_Font2, 13)
            end
        end
    end
end

Yes, yes. I searched for this FontString object by different names e.g. .Text, .text, .title etc. But nothing matched. But regions, it's the perfect method. I didn't come up with it before.

Your code works perfectly.
Thank you Fizzlemizz for your help.

In the XML for the template it's just a

Code:

<ButtonText>

    ...

</ButtonText>

With no name or parentKey attribute to use, you just have to search the child regions of the parent frame and hope there is some easy way to identiy what you want, like being the only FontString child.
