ItemRefTooltip is not fired

[Platine]

Please move this thread to the Lua/XML Help section.

Hello, if I hover over an item in the backpack with the mouse, its description will be displayed in the GameTooltip frame. If they additionally press the Shift key, the description Currently Equipped will be displayed in the ItemRefTooltip frame.



I would like to capture the moment of the ItemRefTooltip frame is showing, but something fails:

ItemRefTooltip:HookScript("OnTooltipSetItem", function(self, ...)
   print("ItemRefTooltip1");      
end );      

ItemRefTooltip:HookScript("OnShow", function(self)
   print("ItemRefTooltip2");      
end );      

ItemRefTooltip:HookScript("OnEnter", function(self)
   print("ItemRefTooltip3");      
end );      

ItemRefTooltip:HookScript("OnLeave", function(self)
   print("ItemRefTooltip4");
end );

The message is not displayed after showing the frame with Currently Equipped.
