Chapter 9X 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.

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 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.
