Getting a DLabel's height with wrapping enabled

[StarFox]

Hello,
I'm trying to make an announcement VGUI and DLabels are being assholes (or maybe I am). I'm trying to get a DLabel's height so I can update the PANEL's height and am terrible failing.
[LUA]
function PANEL:Init()
self.title = self:Add("DLabel")
self.title:SetPos(5, 0)
self.title:SetColor(Color(255, 255, 255))
self.title:SetExpensiveShadow(1, Color(0, 0, 0))
self.title:SetContentAlignment(7)
self.title:SetFont("TitleFont")
self.title:SetText("Announcement")
self.title:SizeToContents()

self.text = self:Add("DLabel")
self.text:SetPos(10, 35)
self.text:SetColor(Color(255, 255, 255))
self.text:SetExpensiveShadow(1, Color(0, 0, 0))
self.text:SetContentAlignment(7)
self.text:SetText("Hello there!\nThe server will be shut down for maintenance tomorrow at 9PM for about 30 minutes.\n\nBye!")
self.text:SetWide(290)
self.text:SetWrap(true)
self.text:SetAutoStretchVertical(true) -- Doesn't update the height value
//self.text:SizeToContentsY() -- Sets Y to a ridiculous value (> 1400)

print(self.text:GetTall()) -- Returns 20 whatever the text
end

Please send help.

I'm now using [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/markup/Parse]markup.Parse[/url] as the wrapping is way more reliable.
