Image area

QPix provides a scrollable plug-in area for displaying disk-based images and 4D picture objects. The area includes a menu bar, a tools widget, and a zoom widget.

To add a QPix area to a form, create a plug-in area object and select _QPix from the popup menu in the properties window. After the area rectangle is created, choose Advanced... from the object properties palette to get to the area's Advanced Properties Dialog. This allows for codeless initial setup of the area; modifications can be done procedurally, by means of the commands described in this chapter.
