1.13.1.3 Drop Target Items
A panel drop target item is a bordered image in a panel area that is used to transfer data to or
from applications. Before you use a panel drop target item you need to be familiar with the
SELECTION and DRAGDROP packages.
A panel drop target item is an object in the class Panel_drop_target_item which is
equivalent to a Panel_item. A drop target item’s owner is a Panel.
1.13.1.4 Panel Extension Items
Panel extension items support additional user defined panel items. Use of this type of panel
item is an advanced topic that is covered in Chapter 25, XView Internals, in the XView Pro-
gramming Manual.

1.13.1.5 Gauges
Gauges are just like sliders, but they are “output only” items. That is, you set the value of the
item and the display of the gauge changes just as it would for sliders. Also, there is no
optional type-in field and there is no slider bar for the user to interactively change the value
of the gauge. The gauge is intended to be used only as a feedback item.
To create a gauge, use the PANEL_GAUGE package.
