Panel:InsertClickableTextStart
Description
Starts the insertion of clickable text for a RichText element. Any text appended with Panel:AppendText between this call and Panel:InsertClickableTextEnd will become clickable text.
The hook PANEL:ActionSignal is called when the text is clicked, with "TextClicked" as the signal name and signalValue as the signal value.
The clickable text is a separate Derma panel which will not inherit the current font from the
RichText.Arguments
Example
Creates a panel with some information on Rich Text panels along with a click-able link to the RichText page.
-- Create a window frame
TextFrame = vgui.Create("DFrame")
TextFrame:SetSize(250, 150)
TextFrame:Center()
TextFrame:SetTitle("RichText")
TextFrame:MakePopup()
-- RichText panel
local richtext = vgui.Create("RichText", TextFrame)
richtext:Dock( FILL )
-- First segment
richtext:InsertColorChange(255, 255, 255, 255)
richtext:AppendText("This is a Rich Text panel — a panel used in Source MP's default chat box and developer console.\n\nSee the ")
-- Second segment
richtext:InsertColorChange(192, 192, 255, 255)
richtext:InsertClickableTextStart("OpenWiki") -- Make incoming text fire the "OpenWiki" value when clicked
richtext:AppendText("Garry's Mod Wiki")
richtext:InsertClickableTextEnd() -- End clickable text here
-- Third segment
richtext:InsertColorChange(255, 255, 255, 255)
richtext:AppendText(" for information on how to use a Rich Text panel.")
-- Background color
function richtext:PerformLayout() self:SetBGColor(Color(32, 32, 46)) end
-- Handle any commands we get from the panel
function richtext:ActionSignal(signalName, signalValue)
-- Some clickable text was clicked
if ( signalName == "TextClicked" ) then
-- Open the wiki
if ( signalValue == "OpenWiki" ) then
gui.OpenURL( "https://wiki.facepunch.com/gmod/Panel:InsertClickableTextStart" )
end
end
end
