This event passes a parameter, whose class is
AbtEwIconHoverHelpCallbackData. The parameter has the following
attributes for specifying settings for the hover help:
- hoverArea (AbtBasicView)
- Specifies the hover area that contains the item under the mouse pointer
- isHoverHelpShown (Boolean)
- Specifies whether or not the hover help is shown
- item (AbtBasicView)
- Specifies the item under the mouse pointer
- labelString (String)
- Specifies the hover help string to display, if any. If the item
under the pointer is a graphic push button, the default hover help string is
the item's labelString attribute. Otherwise, the
default value is nil. A value of nil causes no
hover help to be displayed.
- pointerLocation (Point)
- Specifies the location of the mouse pointer relative to the screen.
Note: | For Window parts, this event is signalled even if showHoverHelp of
hoverHelpDescriptor is set to false, so that the event can still be
used to signal when to remove hover help information from an information
area.
