Panel:SetToFullHeight
Panel:SetToFullHeight()
Description
Sets the height of a RichText element to accommodate the text inside.
This function internally relies on Panel:GetNumLines, so it should be called at least a couple frames after modifying the text using Panel:AppendText
Example
Creates a RichText panel with no set height. The proper height is applied 2 seconds after being created in order to show the difference.
-- Create a window frame
TextFrame = vgui.Create("DFrame")
TextFrame:SetSize(250, 210)
TextFrame:Center()
TextFrame:SetTitle("No set height")
TextFrame:MakePopup()
-- RichText panel
local richtext = vgui.Create("RichText", TextFrame)
richtext:SetPos(10, 30)
richtext:SetWidth(230)
-- Block of text
richtext:AppendText("#ServerBrowser_ServerWarning_MaxPlayers")
function richtext:PerformLayout() self:SetBGColor(Color(0, 0, 0)) end
-- Set to full height after 2 seconds
timer.Simple(2, function()
richtext:SetToFullHeight()
TextFrame:SetTitle("Full set height")
end)
