The Properties palette ObjectARX application contains the Properties palette dialog box implementation, as well as an AutoCAD editor reactor. Third-party applications can use the IAcPpPalette and IAcPpPaletteSet interfaces to add and remove Properties palette tabs.
The Properties palette relies on an embedded Property Inspector control to handle its interaction with object properties. In addition, the Properties palette dialog box contains various controls for picking the selection set, and a combo box for choosing a subset of the currently selected objects.
