Editing WoW:UIHANDLER OnEnter

{{widgethandler}}<br>

== Description ==

The OnEnter handler is called when the user mouse pointer enters the frame.

A typical use for this event is to pop up a help tooltip, or a menu with option choices (for instance on a minimap button). The opposite of OnEnter is [[UIHANDLER OnLeave|OnLeave]]. If you decide to show something in OnEnter you should hide it again in the [[UIHANDLER OnLeave|OnLeave]] event handler.

== Arguments ==

self - the frame being entered

motion - unknown

== Example ==
This example illustrates how to use OnEnter and [[UIHANDLER OnLeave|OnLeave]] to display a mouseover help text in the GameTooltip.

Declare the event handlers in the "Scripts" section of your frame:

 <Frame name="MyFrame">
   <Scripts>
     <OnEnter> MyFrame_OnEnter() </OnEnter>
     <OnLeave> MyFrame_OnLeave() </OnLeave>
   </Scripts>
 </Frame>

Place the actual functions in one of your LUA files:

 function MyFrame_OnEnter()
   GameTooltip_SetDefaultAnchor( GameTooltip, UIParent )
   GameTooltip:SetText( "This text shows up when you mouse over\nthe MyFrame frame" )
   GameTooltip:Show()
 end
 
 function MyFrame_OnLeave()
   GameTooltip:Hide()
 end
