D

derive

(a class from another class) To define a class based on another class. The new class inherits the original's properties and methods .

destructor

A method that an object system calls when you destroy an object (or the object is otherwise no longer needed). The destructor is responsible for cleaning up after the object, returning its memory to the free pool in the process. For example, a class for a TCP connection might have a destructor that closes the connection.

detail

You can attach an extra string when you bind a signal handler to a signal. Any code that emits the signal can include a detail as well; only handlers installed with this detail run.

dialog

(window) A window that interacts with the user in one particular situation and is visible only until its job is complete; therefore, it is a so-called transient window. In the X Window System, there is a difference between transient and program windows ; for example, the window manager handles them differently.

DocBook

A document structure (now XML based) for technical documents, software documentation in particular. DocBook is enormous and it is now the standard for most open -source software, including GNOME.
