How to hide only the tooltips of players?

[Yeah]

hey there!
I'm having a problem with tooltips. My intention is to hide the mouseover-tooltip for other players / creatures / npcs that is by default showen in the right bottom corner (see attachment called "tooltip")

GameTooltip.Show = function() 
            GameTooltip:Hide() 
        end 
GameTooltip:SetScript("OnShow", GameTooltip.Show)

This works fine so far. But if I try to reshow the tooltips there are some problems. With

GameTooltip:SetScript("OnShow", nil)

the tooltip for the players / creatures / npcs is showen again, gut the itemtooltips (see attachment called "Itemtooltip") are not! And I've no idea how to fix this. Reloading the UI is no option!

So I'm desperately looking for a way to hide only the playertooltip in the right bottom corner OR to reshow all the tooltips including the itemtooltips without having to reload the UI.

Someone here with an good idea? Thanks so much...

This should get rid of any random units that are moused over. If the unit is targetted, in your party/raid, or belongs to you, it'll still show.

GameTooltip:SetScript("OnTooltipSetUnit",function(self) if select(2,self:GetUnit())=="mouseover" then self:Hide(); end end);

If you want a more aggressive approach and hide all units, this should do the trick.

GameTooltip:SetScript("OnTooltipSetUnit",function(self) self:Hide(); end);
