An interface or its children can be altered in many ways. This chapter describes APIs for the most common of these.
Note: By default, each CAPI interface runs in its process. It is important to understand that an on-screen interface and its elements must be accessed only in the process of that interface. In most circumstances the user alters the interface by a callback inside the interface, which will automatically happen in the correct process. However, calls from other processes (including other CAPI interfaces) should use
. See the LispWorks
CAPI Reference Manual
for details of these functions.
