Why can't an EditBox's value be set during PLAYER_ENTERING_WORLD ?

[Stijn]

Hello,

I'm looking for some clarification on why this doesn't work.

This correctly reports the value when pressing Escape, but the EditBox shows as empty.

local criteria_value = CreateFrame("EditBox", nil, panel, "InputBoxTemplate")
criteria_value:SetWidth(40)
criteria_value:SetHeight(19)
criteria_value:SetPoint("LEFT", criteria_label, "RIGHT", 10, 0)
criteria_value:SetAutoFocus(false)
criteria_value:SetMaxLetters(2)
criteria_value:SetScript("OnEscapePressed",
    function(self)
        criteria_value:ClearFocus()
        print("criteria_value:GetText() : " .. criteria_value:GetText())
    end)

local function event_handler(self, event, ...)
    criteria_value:SetText(WATCHFRAME_CRITERIA_PER_ACHIEVEMENT)
    print("criteria_value:GetText() : " .. criteria_value:GetText())
end

panel:RegisterEvent("PLAYER_ENTERING_WORLD")
panel:SetScript("OnEvent", event_handler)

This works.

local criteria_value = CreateFrame("EditBox", nil, panel, "InputBoxTemplate")
criteria_value:SetWidth(40)
criteria_value:SetHeight(19)
criteria_value:SetPoint("LEFT", criteria_label, "RIGHT", 10, 0)
criteria_value:SetAutoFocus(false)
criteria_value:SetMaxLetters(2)
criteria_value:SetScript("OnEscapePressed",
	function(self)
		criteria_value:ClearFocus()
		print("criteria_value:GetText() : " .. criteria_value:GetText())
	end)
criteria_value:SetScript("OnShow", function(self)
		self:SetText(WATCHFRAME_CRITERIA_PER_ACHIEVEMENT)
	end)

Combining both makes it fail again.

local criteria_value = CreateFrame("EditBox", nil, panel, "InputBoxTemplate")
criteria_value:SetWidth(40)
criteria_value:SetHeight(19)
criteria_value:SetPoint("LEFT", criteria_label, "RIGHT", 10, 0)
criteria_value:SetAutoFocus(false)
criteria_value:SetMaxLetters(2)
criteria_value:SetScript("OnEscapePressed",
	function(self)
		criteria_value:ClearFocus()
		print("criteria_value:GetText() : " .. criteria_value:GetText())
	end)
criteria_value:SetScript("OnShow", function(self)
		self:SetText(WATCHFRAME_CRITERIA_PER_ACHIEVEMENT)
	end)

local function event_handler(self, event, ...)
	criteria_value:SetText(WATCHFRAME_CRITERIA_PER_ACHIEVEMENT)
	print("criteria_value:GetText() : " .. criteria_value:GetText())
end

panel:RegisterEvent("PLAYER_ENTERING_WORLD")
panel:SetScript("OnEvent", event_handler)

The following works just fine for me:

local editBox = CreateFrame('EditBox', nil, UIParent, 'InputBoxTemplate')
editBox:SetWidth(40)
editBox:SetHeight(19)
editBox:SetAutoFocus(false)
editBox:SetMaxLetters(2)
editBox:SetPoint('CENTER')
editBox:Show()

editBox:SetScript('OnEvent', function(self, event, ...)
	self:SetText(WATCHFRAME_CRITERIA_PER_ACHIEVEMENT)
	print("text: " .. self:GetText())
end)
editBox:RegisterEvent('PLAYER_ENTERING_WORLD')

Are you sure that you aren't overwriting the 'OnEvent' handler for panel somewhere else in your code?

That works indeed.
I should have mentioned, the EditBox is located in an InterfaceOptions category.
