1. Everything works except that the EventHandle function isn't even run... I think there's something wrong with the event...

    Why isn't it working?

     IgnoreDuel = {}
    
     IgnoreDuel.Frame = CreateFrame("Frame", nil, UIParent)
     IgnoreDuel.CheckButton = CreateFrame("CheckButton", nil, IgnoreDuel.Frame)
     IgnoreDuel.Text = IgnoreDuel.Frame:CreateFontString()
    
     IgnoreDuel.CheckButton:SetWidth("25")
     IgnoreDuel.CheckButton:SetHeight("25")
     IgnoreDuel.Frame:SetWidth("132")
     IgnoreDuel.Frame:SetHeight("60")
    
     IgnoreDuel.Text:SetFontObject(GameFontNormal)
     IgnoreDuel.Text:SetPoint("CENTER", IgnoreDuel.Frame, "CENTER", 0, 12)
     IgnoreDuel.CheckButton:SetPoint("CENTER", IgnoreDuel.Frame, "CENTER", 0, -12)
     IgnoreDuel.Frame:SetPoint("TOP", UIParent, "TOP", 0, -72)
    
     IgnoreDuel.CheckButton:SetNormalTexture("Interface\\Buttons\\UI-CheckBox-Up") 
     IgnoreDuel.CheckButton:SetPushedTexture("Interface\\Buttons\\UI-CheckBox-Down") 
     IgnoreDuel.CheckButton:SetHighlightTexture("Interface\\Buttons\\UI-CheckBox-Highlight", "ADD") 
     IgnoreDuel.CheckButton:SetCheckedTexture("Interface\\Buttons\\UI-CheckBox-Check") 
    
     IgnoreDuel.Text:SetText("Toggle Duel Ignore")
    
     IgnoreDuel.Frame:SetBackdrop( {
        bgFile = [[Interface\Tooltips\UI-Tooltip-Background]],
        edgeFile = [[Interface\Tooltips\UI-Tooltip-Border]],
        tile = true, tileSize = 16, edgeSize = 16,
        insets = { left = 5, right = 5, top = 5, bottom = 5 }
     })
    
     IgnoreDuel.Frame:SetBackdropColor(.75, .75, .75, .75)
     IgnoreDuel.Frame:SetBackdropBorderColor(1, 1, 1, 1)
    
     function IgnoreDuel.EventHandle(self, event, ...)
        if(event == "DUEL_REQUESTED") then
            if(IgnoreDuel.CheckButton:GetChecked() == true) then
                CancelDuel()
            end
        end
     end
    
     IgnoreDuel.Frame:RegisterEvent("DUEL_REQUESTED")
     IgnoreDuel.Frame:SetScript("OnEvent", EventHandle)
    
  2. It's possible. Add a print statement to your event handler to see if it's being called. YOu can also use /eventtrace to see what events are firing.

  3. I put print in the event handler, it didn't show the print.

    EDIT: I forgot the . prefix before the EventHandle, it works now.
