Hide any hover popups that are currently showing on the control. When {@link #setShowHover(boolean)} has been set to
true
, adecoration's description text will be shown in an info hover over the field's control as long as the mouse hovers over the decoration, and will be hidden when the mouse exits the decoration. This method can be used to hide a hover, whether it was shown explicitly using {@link #showHoverText(String)}, or was showing because the user was hovering in the decoration.
This message has no effect if there is no current hover.
