+== Arguments ==
-Adds Line with text to tooltip.
+:;text : {{api|string|t=t}} - text which will appear in new tooltip line
+:;red : number range 0 to 1 - red color value for text string
+:;green : number range 0 to 1 - green color value for text string

+:none
-:(tooltipText [, textColor.r, textColor.g, textColor.b [, wrapText]])
+== Examples ==
+ MyTooltip:SetOwner(TargetFrame, "ANCHOR_RIGHT")
+ MyTooltip:AddLine("New tooltip line", 1, 1, 1)
+ MyTooltip:Show()
-:;tooltipText : String - string which will appear in new tooltip line
+== Details ==
+Note that this only appends the new line to the tooltip. It does not update the tooltip's height/width, so that the newly added line initially appears underneath (outside of) the tooltip.
-:;textColor.r : range 0 to 1 - red color value for text string
+A subsequent call to [[API_Region_Show|GameTooltip:Show()]] will update the tooltip's borders correctly.
-:;textColor.g : range 0 to 1 - green color value for text string
-:;textColor.b : range 0 to 1 - blue color value for text string
-:;wrapText : nil or 1 - Set to 1 to wrap text.
-----
+== Notes ==
-;''Returns''
+* As of WoW 2.0, there is no longer a maximum number of lines.
+* As of 6.0 uses Lua boolean, rather than WoW Boolean (nil or 1) for wrap text setting.
