=head1 NAME
Prima::DockManager - advanced dockable widgets
=head1 DESCRIPTION
C<Prima::DockManager> contains classes that implement additional
functionality within the dockable widgets paradigm.
The module introduces two new dockable widget classes:
C<Prima::DockManager::Panelbar>, a general purpose
dockable container for variable-sized widgets; and C<Prima::DockManager::Toolbar>,
a dockable container for fixed-size command widgets, mostly push buttons.
The command widgets, nested in a toolbar, can also be docked.
C<Prima::DockManager> class is an application-oriented class in a way
that ( mostly ) the only instance of it is needed in the program. It
is derived from C<Prima::Component> and therefore is never visualized.
The class instance is stored in C<instance> property of all module classes
to serve as a docking hierarchy root. Through the document, I<instance>
term is referred to C<Prima::DockManager> class instance.
The module by itself is not enough to make a docking-aware application work
effectively. The reader is urged to look at F<examples/dock.pl>
example code, which demonstrates the usage and capabilities of
the module.
=head1 Prima::DockManager::Toolbar
A toolbar widget class. The toolbar has a dual nature; it can dock
and accept docking widgets simultaneously. In the scope of C<Prima::DockManager>,
the toolbar hosts command widget, mostly push buttons.
The toolbar consists of two widgets. The external dockable widget is
implemented in C<Prima::DockManager::Toolbar>, and the internal dock
in C<Prima::DockManager::ToolbarDocker> classes.
=head2 Properties
=over
=item autoClose BOOLEAN
Selects the behavior of a toolbar when all of its command widgets are
undocked. If 1, the toolbar is automatically destroyed. If 0
it calls C<visible(0)>.
=item childDocker WIDGET
Pointer to C<Prima::DockManager::ToolbarDocker> instance.
See also C<Prima::DockManager::ToolbarDocker::parentDocker>.
=item instance INSTANCE
C<Prima::DockManager> instance, the docking hierarchy root.
=back
=head1 Prima::DockManager::ToolbarDocker
Internal class, implements a dock widget for command widgets,
while serves as a client in a dockable toolbar, which is
a C<Prima::LinearDockerShuttle> descendant. When its size is
changed due an eventual rearrange of its docked widgets, also resizes
the toolbar.
=head2 Properties
=over
=item instance INSTANCE
C<Prima::DockManager> instance, the docking hierarchy root.
=item parentDocker WIDGET
Pointer to C<Prima::DockManager::Toolbar> instance. When in
the docked state, C<parentDocker> value is always equals to C<owner>.
See also C<Prima::DockManager::Toolbar::childDocker>.
=back
=head2 Methods
=over
=item get_extent
Calculates the minimal rectangle that encloses all docked widgets
and returns its extensions.
=item update_size
Called when size is changed to resizes the owner widget. If it is in the docked
state, the size change might result in change of position or docking state.
=back
=head1 Prima::DockManager::Panelbar
The class is derived from C<Prima::LinearDockerShuttle>, and
is different only in that C<instance> property is introduced,
and the external shuttle can be resized interactively.
The class is to be used as a simple host to sizeable widgets.
The user can dispose of the panel bar by clicking close button
on the external shuttle.
=head2 Properties
=over
=item instance INSTANCE
C<Prima::DockManager> instance, the docking hierarchy root.
=back
=head1 Prima::DockManager
A binder class, contains set of functions that groups
toolbars, panels, and command widgets together under the docking
hierarchy.
The manager servers several purposes.
First, it is a command state holder: the command
widgets, mostly buttons, usually are in enabled or disabled state in different
life stages of a program. The manager maintains the enabled/disabled state
by assigning each command an unique scalar value ( farther and in the
code referred as I<CLSID> ). The toolbars can be created with set of
command widgets, referred via these CLSIDs. The same is valid for
the panels - although they do not host command widgets, the widgets that
they do host can also be created indirectly via CLSID identifier.
In addition to CLSID, the commands can be grouped by sections.
Both CLSID and group descriptor scalars are defined by the programmer.
Second, C<create_manager> method presents a standard configuration
widget, that allows rearranging of normally non-dockable command widgets,
by presenting a full set of available commands to the user as icons.
Dragging the icons to toolbars, dock widgets or merely outside the
configuration widget automatically creates the corresponding command widget.
The notable moment here is that the command widgets are not required
to know anything about dragging and docking; any C<Prima::Widget>
descendant can be used as a command widget.
Third, it helps maintaining the toolbars and panels visibility
when the main window is hidden or restored. C<windowState> method
hides or shows the toolbars and panels effectively.
Fourth, it serves as a docking hierarchy root. All docking sessions
begin from C<Prima::DockManager> object, which although does not provide
docking capabilities itself ( it is C<Prima::Component> descendant ),
redirects the docking requests to the lower-level dock widgets.
Fifth, it provides number of helper methods and notifications,
and enforces use or C<fingerprint> property by all dockable widgets.
This property has default value of C<0xFFFF> ( defined in C<Prima::Docks> ).
The module contains the fingerprint C<dmfp::XXX> constants with value greater than this,
so the toolbars and panels are not docked to a dock widget with the default
configuration. The base constant set is:
fdmp::Tools ( 0x0F000) - dock the command widgets
fdmp::Toolbar ( 0x10000) - dock the toolbars
fdmp::LaunchPad ( 0x20000) - allows widgets recycling
All this functionality is demonstrated in F<examples/dock.pl>
example.
=head2 Properties
=over
=item commands HASH
A hash of boolean values, with keys of CLSID scalars.
If value is 1, the command is available. If 0, the command
is disabled. Changes to this property are reflected in the
visible command widgets, which are enabled or disabled
immediately. Also, C<CommandChange> notification is triggered.
=item fingerprint INTEGER
The property is read-only, and always returns C<0xFFFFFFFF>,
to allow landing for all dockable widgets. In case when a finer
granulation is needed, the default C<fingerprint> values of
toolbars and panels can be reset.
=item interactiveDrag BOOLEAN
If 1, the command widgets can be interactively dragged,
created and destroyed. This property is usually operated together
with C<create_manager> widget. If 0, the command widgets
cannot be dragged.
Default value: 0
=back
=head2 Methods
=over
=item activate
Brings to front all toolbars and panels. To be
used inside a callback code of a main window, that has
the toolbars and panels attached to:
onActivate => sub { $dock_manager-> activate }
=item auto_toolbar_name
Returns an unique name for an automatically created
toolbar, like C<Toolbar1>, C<Toolbar2> etc.
=item commands_enable BOOLEAN, @CLSIDs
Enabled or disables commands from CLSIDs array.
The changes are reflected in the visible command widgets, which
are enabled or disabled immediately.
Also, C<CommandChange> notification is triggered.
=item create_manager OWNER, %PROFILE
Inserts two widgets into OWNER with PROFILE parameters:
a listbox with command section groups, displayed as items, that usually correspond to
the predefined toolbar names, and a notebook that displays the
command icons. The notebook pages are interactively selected by the listbox
navigation.
The icons, dragged from the notebook, behave as dockable widgets:
they can be landed upon a toolbar, or any other dock widget, given
it matches the C<fingerprint> ( by default C<dmfp::LaunchPad|dmfp::Toolbar|dmfp::Tools>).
C<dmfp::LaunchPad> constant allows the recycling; if a widget is dragged
back onto the notebook, it is destroyed.
Returns two widgets, the listbox and the notebook.
PROFILE recognizes the following keys:
=over
=item origin X, Y
Position where the widgets are to be inserted.
Default value is 0,0.
=item size X, Y
Size of the widget insertion area. By default
the widgets occupy all OWNER interior.
=item listboxProfile PROFILE
Custom parameters, passed to the listbox.
=item dockerProfile PROFILE
Custom parameteres, passed to the notebook.
=back
=item create_panel CLSID, %PROFILE
Creates a dockable panel of a previously registered CLSID
by C<register_panel>. PROFILE recognizes the following keys:
=over
=item profile HASH
Hash of parameters, passed to C<create()> of the panel widget class.
Before passing it is merged with the set of parameters, registered
by C<register_panel>. The C<profile> hash takes the precedence.
=item dockerProfile HASH
Constains extra options, passed to C<Prima::DockManager::Panelbar>
widget. Before the usage it is merged with the set of parameters,
registered by C<register_panel>.
NB: The C<dock> key here contains a reference to a desired dock widget.
If C<dock> set to C<undef>, the panel is created in the non-docked state.
=back
Example:
$dock_manager-> create_panel( $CLSID,
dockerProfile => { dock => $main_window }},
profile => { backColor => cl::Green });
=item create_tool OWNER, CLSID, X1, Y1, X2, Y2
Inserts a command widget, previously registered with CLSID by C<register_tool>, into
OWNER widget with X1 - Y2 coordinates. For automatic maintenance of
enable/disable state of command widgets OWNER is expected to be a
toolbar. If it is not, the maintenance must be performed separately,
for example, by C<CommandChange> event.
=item create_toolbar %PROFILE
Creates a new toolbar of C<Prima::DockManager::Toolbar> class.
The following PROFILE options are recognized:
=over
=item autoClose BOOLEAN
Sets C<autoClose> property of the toolbar.

the toolbar is created in the non-docked state.
=item dockerProfile HASH
Parameters passed to C<Prima::DockManager::Toolbar> as
creation properties.

if the class is not registered. The hash format contains
the following keys:
=over
=item class STRING
Widget class
=item profile HASH

The action member of the menu item record is set to CALLBACK scalar.
=item toolbar_visible TOOLBAR, BOOLEAN
Sets the visibility of a TOOLBAR.
If VISIBLE is 0, the toolbar is hidden; if 1, it is shown.
=item toolbars
Returns all toolbar widgets in an array.
=item windowState INTEGER
Mimics interface of C<Prima::Window::windowState>, and maintains
visibility of toolbars and panels. If the parameter is C<ws::Minimized>,

=item class IMAGE, CLSID, %PROFILE
Builds a hash with parameters, ready to feed C<Prima::DockManager::register_tool>
for registering a C<Prima::SpeedButton> class instance with PROFILE parameters.
IMAGE is a path to a image file, loaded and stored in the registration hash.
IMAGE provides an extended syntax for indicating a frame index, if the image file is multiframed: the frame index is appended to the path name
with C<:> character prefix.
CLSID scalar is not used; it is returned so the method result can
directly be passed into C<register_tool> method.
Returns two scalars: CLSID and the registration hash.
Example:
$dock_manager-> register_tool(
Prima::DockManager::S::SpeedButton::class( "myicon.gif:2",
q(CLSID::Logo), hint => 'Logo image' ));
