[1.7.10] How Can I Disable Held Item Tooltips

My mod creates a highly configurable HUD from the anime Sword Art Online, and im working on replacing the hotbar.  I have sucesfully created a vertical hotbar at the top right corner of the screen, and disabled the old one by canceling the ElementType.HOTBAR event using setCanceled(true).  But i still cant seem to get rid of the fading text that appears above the hotbar whenever you switch items.  Is there a way to disable this?

Thanks in advance
