NAME

QWizard_Widgets - Describes the Widgets available to QWizard Generators

OVERVIEW

This document describes the various QWizard backend widgets that can be produced and what tags they support, and what the values of those tags are expected to produce (either by direct value such as

  tag => "string"

or as a result of a code execution like

  tag => sub { return "string" }

or even:

  tag => [sub { return $_[$#_] }, "string"]

Tag Value Expectations

The documentation to follow will reference a number of different value types for various tags. These possible values are described below:

single

A single value is expected for this tag. If a subroutine returns multiple values only the first will be used.

multi

The tag expects or can accept multiple values. These values should be specified in the form of an array reference.

norecuse

This is a special form of "multi"... I need to go look at the code again to remember exactly what it does.

values,labels

This is a special tag to indicate the widget needs both values and labels associated with the multiple sub-widgets it can display (radio boxes, menu items, check boxes, ...). The values tag (an array ref) will indicate which values are used within the program. The labels clause will map those values to human strings. The labels clause can be either a hash mapping values to labels, or an array where the even elements of the array (0, 2, 4, ...) will be the values and the odd elements (1, 3, 5, ...) will be the labels to associate with them. An array reference for labels allows the order of label presentation to be specified, where as a hash will display the labels/sub-widgets in a somewhat random order.

If the labels clause is left out, the values themselves will be present to the user.

If the values clause is left out, the values will be pulled from the labels.

It is likely a rare case that you need to specify both. This special tag name specifically indicates you can specify both.

forced

This is a value which is forced for a particular tag for internal use and can\'t be manipulated by the programmer. It\'s documented here anyway for completeness.

Notes about this document.

1)

This file is automatically generated from the Generator\'s own expect ions of their supported widgets and the requirements. Thus, not all widgets in all generators are perfectly equal. Some generators have better support for extra options for certain widgets, for example.

2)

This document does not specify some of the other tags that every question is allowed to have, such as "name", "text", "helpddesc", "check_value", ... It only discusses the tags that the back end generators make use of.
