X Property Library
_____________________________________________________________________________
This chapter describes the functions in the Lab/Windows CVI X Property Library. The X
Property Library contains functions that read and write properties to and from X Windows. The
X Property Library Overview section contains general information about the X Property Library
functions and panels. The X Property Library Function Reference section contains an
alphabetical list of function descriptions.
These functions provide a mechanism for communication among X clients. This library provides
capabilities similar to those available in the TCP library, but differs from the TCP library in the
following significant ways.
• It conforms to a conventional method for X interclient communication.
• It works between any X clients that are connected to the same display, and does not require
any particular underlying communication protocol such as TCP.
• It provides a method for sharing data among X clients without explicit point-to-point
connections between them.
The X Property Library Overview section contains general information about the X Property
Library. The X Property Library Function Reference section alphabetically lists function names,
with descriptions.
X Property Library Overview
The X Property Library is available only in the UNIX versions of LabWindows/CVI. This
section contains general information about the X Property Library functions and panels.
The X Property Library Function Panels
The X Property Library function panels are grouped in a tree structure according to the types of
operations performed. The X Property Library Function tree appears in Table 9-1.
The first- and second-level bold headings in the tree are the names of function classes and
subclasses. Function classes and subclasses are groups of related function panels. The third-
level headings in plain text are the names of individual function panels. Each X Property Library
function panel generates an X Property Library function call. The name of the function is in bold
italics to the right of the function panel name.
