Defining a List within a Structure within an Associative Array

PV-WAVE Foundation > Programmer Guide > Working with Lists and Associative Arrays > Defining a List within a Structure within an Associative Array

The following example shows how to nest a structure and a list within an associative array. This example has applications in GUI tool development, where associative arrays can be used to store information about the attributes of a GUI tool.

; Define a data structure to hold variables and attributes for a

; GUI tool.

strDef = {Main_Data_Str, attrs:ASARR(), vars: LIST()}

; Create an empty associative array that will hold the GUI tool

; data structure. This array will be filled in later, possibly

; in another procedure.

dataStr = ASARR()

; Call the tool Wg1.

dataStr('Wg1') = {Main_Data_Str}

; Set a size attribute for the Wg1 tool.

dataStr('Wg1').attrs('size') = [512, 512]

; Set a list of variables for the Wg1 tool.

dataStr('Wg1').vars = LIST('VAR1', 'VAR2')
