=head1 NAME

Prima::VB::Classes - Visual Builder widgets and types

=head1 DESCRIPTION

Visual Builder is designed without a prior knowledge of the 
widget classes that would be contained in its widget palette.
Instead, it provides a registration interface for new widgets and their specific properties.

This document describes API, provided by the builder, and the widget
interface. Through the document, I<widget> or I<widget class> mean
not the original widget or class, but their representatives.

=head1 USAGE

The widget must provide specific methods to cooperate with the builder.
It is not required, however, to contain these methods in its base module
or package; it can delegate its representation to another, usually
very light class, which is used by the builder.

Such a class must be derived from C<Prima::VB::Object>, which provides
base functionality. One of basic features here is overloading of
property change method. Since the user can change any property interactively,
the class can catch the properties of interest by declaring C<prf_XXX>
method, where XXX is the property name. C<Prima::VB::Widget> declares
set of these methods, assuming that a widget would repaint when, for example,
its C<color> or C<font> properties change.

The hierarchy of VB classes mimics the one of the core toolkit classes,
but this is a mere resemblance, no other dependencies except the names
are present. The hierarchy is as follows:

	Prima::VB::Object   Prima::Widget
		Prima::VB::Component
			Prima::VB::Drawable
				Prima::VB::Widget
					Prima::VB::Control
						Prima::VB::Window

NB: C<Prima::VB::CoreClasses> extends the hierarchy to the full set of default
widget palette in the builder. This module is not provided with documentation
though since its function is obvious and its code is trivial.

Since the real widgets are used in the interaction with the builder,
their properties are not touched when changed by the object inspector
or otherwise. The widgets 
keep the set of properties in a separated hash. The properties are 
accessible by C<prf> and C<prf_set> methods.

A type object is a class used to represent a particular type of
property in object inspector window in the builder.
The type objects, like the widget classes, also are not hard-coded. The builder
presents a basic set of the type objects, which can be easily expanded.
The hierarchy ( incomplete ) of the type objects classes is as follows:

	Prima::VB::Types::generic
		Prima::VB::Types::bool
		Prima::VB::Types::color
		Prima::VB::Types::point
		Prima::VB::Types::icon
		Prima::VB::Types::Handle
		Prima::VB::Types::textee
			Prima::VB::Types::text
			Prima::VB::Types::string
				Prima::VB::Types::char
				Prima::VB::Types::name
				Prima::VB::Types::iv
					Prima::VB::Types::uiv

The document does not describe the types, since their function
can be observed at runtime in the object inspector.
Only C<Prima::VB::Types::generic> API is documented.

=head1 Prima::VB::Object

=head2 Properties

=over

=item class STRING

Selects the original widget class. Create-only property.

=item creationOrder INTEGER

Selects the creation order of the widget.

=item module STRING

Selects the module that contains the original widget class. Create-only property.

=item profile HASH

Selects the original widget profile. Create-only property.
Changes to profile at run-time performed by C<prf_set> method.

=back

=head2 Methods

=over

=item act_profile

Returns hash of callbacks to be stored in the form file and
executed by C<Prima::VB::VBLoader> when the form file is loaded.
The hash keys are names of VBLoader events and values - strings
with code to be eval'ed. See L<Prima::VB::VBLoader/Events>
for description and format of the callbacks.

Called when the builder writes a form file.

=item add_hooks @PROPERTIES

Registers the object as a watcher to set of PROPERTIES.
When any object changes a property listed in the hook record,
C<on_hook> callback is triggered.

Special name C<'DESTROY'> can be used to set a hook on object destruction event.


=item ext_profile

Returns a class-specific hash, written in a form file.
Its use is to serve as a set of extra parameters, passed from
the builder to C<act_profile> events.

=item prf_set %PROIFLE

A main method for setting a property of an object.
PROFILE keys are property names, and value are property values.

=item prf_adjust_default PROFILE, DEFAULT_PROFILE

DEFAULT_PROFILE is a result of C<profile_default> call 
of the real object class. However, not all properties usually
are exported to the object inspector. C<prf_adjust_default>
deletes the unneeded property keys from PROFILE hash.

=item prf_delete @PROPERTIES

Removes PROPERTIES from internal properties hash.
This action results in that the PROPERTIES in the object inspector
are set back to their default values.

=item prf_events 

Returns hash of a class-specific events. These appear in
the object inspector on C<Events> page. The hash keys are
event names; the hash values are default code pieces,
that describe format of the event parameters. Example:

	sub prf_events { return (
		$_[0]-> SUPER::prf_events,
		onSelectItem  => 'my ( $self, $index, $selectState) = @_;',
	)}

=item prf @PROPERTIES

Maps array of PROPERTIES names to their values. If called
in scalar context, returns the first value only; if in array 
context, returns array of property values.

=item prf_types

Returns an anonymous hash, where keys are names of
the type class without C<Prima::VB::Types::> prefix,
and values are arrays of property names.

This callback returns an inverse mapping of properties
by the types.

=item prf_types_add PROFILE1, PROFILE2

Adds PROFILE2 content to PROFILE1. PROFILE1 and PROFILE2 are 
hashes in format of result of C<prf_types> method.

=item prf_types_delete PROFILE, @NAMES

Removes @NAMES from PROFILE. Need to be called if property type if redefined
through the inheritance.

=item remove_hooks @PROPERTIES

Cancels watch for set of PROPERTIES.

=back

=head2 Events

=over

=item on_hook NAME, PROPERTY, OLD_VALUE, NEW_VALUE

Called for all objects, registered as watchers
by C<add_hooks> when PROPERTY on object NAME is changed
from OLD_VALUE to NEW_VALUE. Special PROPERTY C<'DESTROY'>
hook is called when object NAME is destroyed.

=back

=head1 Prima::VB::Component

=head2 Properties

=over

=item marked MARKED , EXCLUSIVE

Selects marked state of a widget. If MARKED flag is 1, the widget is
selected as marked. If 0, it is selected as unmarked.
If EXCLUSIVE flag is set to 1, then all marked widgets are unmarked
before the object mark flag is set.

=item sizeable BOOLEAN

If 1, the widget can be resized by the user.
If 0, in can only be moved.

=item mainEvent STRING

Selects the event name, that will be opened in the object inspector
when the user double clicks on the widget.

=back

=head2 Methods

=over

=item common_paint CANVAS

Draws selection and resize marks on the widget
if it is in the selected state. To be called from
all C<on_paint> callbacks.

=item get_o_delta 

Returns offset to the owner widget. Since the builder does
not insert widgets in widgets to reflect the user-designed
object hierarchy, this method is to be used to calculate
children widgets relative positions.

=item xy2part X, Y

Maps X, Y point into part of widget. If result is not
equal to C<'client'> string, the event in X, Y point
must be ignored.

=item iterate_children SUB, @ARGS

Traverses all children widget in the hierarchy,
calling SUB routine with widget, self, and @ARGS
parameters on each.

=item altpopup

Invokes an alternative, class-specific popup menu, if present.
The popup object must be named C<'AltPopup'>.

=back

=head2 Events

=over

=item Load

Called when the widget is loaded from a file or the clipboard.

=back

=head1 Prima::VB::Types::generic

Root of all type classes. 

A type class can be used with 
and without object instance. The instantiated class
contains reference to ID string, which is a property
name that the object presents in the object inspector,
and WIDGET, which is the property applied to. When
the object inspector switches widgets, the type object
is commanded to update the references.

A class must also be usable without object instance,
in particular, in C<write> method. It is called to
export the property value in a storable format
as a string, better as a perl-evaluable expression.

=head2 Methods

=over


=item new CONTAINER, ID, WIDGET

Constructor method. CONTAINER is a panel widget in the object
inspector, where the type object can insert property value
selector widgets.

=item renew ID, WIDGET

Resets property name and the widget.

=item quotable STRING

Returns quotable STRING.

=item printable STRING

Returns a string that can be stored in a file.

=back

=head2 Callbacks

=over

=item change

Called when the widget property value is changed.

=item change_id

Called when the property name ( ID ) is changed.
The type object may consider update its look
or eventual internal variables on this event.

=item get

Returns property value, based on the selector widgets value.

=item open

Called when the type object is to be visualized first time.
The object must create property value selector widgets
in the C<{container}> panel widget.

=item preload_modules

Returns array of strings of modules, needed to be pre-loaded
before a form file with type class-specific information can be loaded.
Usually it is used when C<write> method
exports constant values, which are defined in another module.

=item set DATA

Called when a new value is set to the widget property by means other than the 
selector widgets, so these can be updated. DATA is the property new value.

=item valid

Checks internal state of data and returns a boolean
flag, if the type object data can be exported and
set to widget profile.

=item write CLASS, ID, DATA

Called when DATA is to be written in form.
C<write> must return such a string that 
can be loaded by C<Prima::VB::VBLoader> later.
