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 OnLeave. If you decide to show something in OnEnter you should hide it again in the OnLeave event handler.

Example

This example illustrates how to use OnEnter and 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
