Open Appearance

Open appearance is most commonly used for an OLE embedded object, but it can also apply in other situations where the user opens an object into its own window. To indicate that an object is "open," display the object in its container's window overlaid with a set of hatched (45 degree) lines drawn every four pixels, as shown in Figure 13.34.

Note
For more information about the use of open appearance for OLE embedded objects, see Chapter 11, "Working with OLE Embedded and OLE Linked Objects."

If the opened object is selected, display the hatched lines using the system highlight color. When the opened object is not selected, display the lines using the system's setting for window text color.
