Overview
Each type of descriptor is stored as an individual XML element situated within the <description> element of one macro screen.
You do not have to understand all the types of descriptors at first.
Instead you should begin by becoming familiar with just two types:
- The Fields Counts and OIA descriptor (actually contains 3 individual descriptors)
- The String descriptor
Types of descriptors, how many of
each type allowed lists all the types of descriptors
and shows the number of descriptors of each type that are allowed
to exist in one macro screen (more specifically, in one <description>
element belonging to one <screen> element):
The following subsections describe each type of descriptor
in detail.
Type of descriptor: | Number of this type of descriptor allowed per macro screen: |
---|---|
Field Counts and OIA | 1 (required) |
String descriptor | 0 or more |
Cursor descriptor | 0 or 1 |
Attribute descriptor | 0 or more |
Condition descriptor | 0 or more |
