=head1 NAME
Prima::MDI - top-level windows emulation classes
=head1 DESCRIPTION
MDI stands for Multiple Document Interface, and is a Microsoft Windows user
interface, that consists of multiple non-toplevel windows belonging to an
application window. The module contains classes that provide similar
functionality; sub-window widgets realize a set of operations, close to those
of the real top-level windows, - iconize, maximize, cascade etc.
The basic classes required to use the MDI are C<Prima::MDIOwner> and
C<Prima::MDI>, which are, correspondingly, sub-window owner class and
sub-window class. C<Prima::MDIWindowOwner> is exactly the same as
C<Prima::MDIOwner> but is a C<Prima::Window> descendant: the both owner classes
are different only in their first ascendants. Their second ascendant is
C<Prima::MDIMethods> package, that contains all the owner class functionality.
Usage of C<Prima::MDI> class extends beyond the multi-document paradigm.
C<Prima::DockManager> module uses the class as a base of a dockable toolbar
window class ( see L<Prima::DockManager>.
=head1 SYNOPSIS
use Prima::MDI;
my $owner = Prima::MDIWindowOwner-> create();
my $mdi = $owner-> insert( 'Prima::MDI');
$mdi-> client-> insert( 'Prima::Button' => centered => 1 );
=head1 Prima::MDI
Implements MDI window functionality. A subwindow widget consists of a titlebar,
titlebar buttons, and a client widget. The latter must be used as an insertion
target for all children widgets.
A subwindow can be moved and resized, both by mouse and keyboard. These
functions, along with maximize, minimize, and restore commands are accessible
via the toolbar-anchored popup menu. The default set of commands is as follows:
Close window - Ctrl+F4
Restore window - Ctrl+F5 or a double click on the titlebar
Maximize window - Ctrl+F10 or a double click on the titlebar
Go to next MDI window - Ctrl+Tab
Go to previous MDI window - Ctrl+Shift+Tab
Invoke popup menu - Ctrl+Space
The class mimics API of C<Prima::Window> class, and in some extent
L<Prima::Window> and this page share the same information.
=head2 Properties
=over
=item borderIcons INTEGER
Selects window decorations, which are buttons on titlebar and the titlebar itself.
Can be 0 or a combination of the following C<mbi::XXX> constants, which are supreset
of C<bi::XXX> constants ( see L<Prima::Window/borderIcons> ) and are interchangeable.
mbi::SystemMenu - system menu button with icon is shown
mbi::Minimize - minimize button
mbi::Maximize - maximize ( and eventual restore )
mbi::TitleBar - window title
mbi::Close - close button
mbi::All - all of the above
Default value: C<mbi::All>
=item borderStyle INTEGER
One of C<bs::XXX> constants, selecting the window border style.
The constants are:
bs::None - no border
bs::Single - thin border
bs::Dialog - thick border
bs::Sizeable - thick border with interactive resize capabilities
C<bs::Sizeable> is an unique mode. If selected, the user
can resize the window interactively. The other border styles
disallow resizing and affect the border width and design only.
Default value: C<bs::Sizeable>
=item client OBJECT
Selects the client widget at runtime. When changing the client, the old client
children are not reparented to the new client. The property cannot be used to
set the client during the MDI window creation; use
C<clientClass> and C<clientProfile> properties instead.
When setting new client object, note that is has to be named C<MDIClient>
and the window is automatically destroyed after the client is destroyed.
=item clientClass STRING
Assigns client widget class.
Create-only property.
Default value: C<Prima::Widget>
=item clientProfile HASH
Assigns hash of properties, passed to the client during the creation.
Create-only property.
=item dragMode SCALAR
A three-state variable, which governs the visual feedback style when the user
moves or resizes a window. If 1, the window is moved or resized simultaneously
with the user mouse or keyboard actions. If 0, a marquee rectangle is drawn,
which is moved or resized as the user sends the commands; the window is
actually positioned and / or resized after the dragging session is successfully
finished. If C<undef>, the system-dependant dragging style is used. ( See
L<Prima::Application/get_system_value> ).
The dragging session can be aborted by
hitting Esc key or calling C<sizemove_cancel> method.
Default value: C<undef>.
=item icon HANDLE
Selects a custom image to be drawn in the left corner of the toolbar. If 0,
the default image ( menu button icon ) is drawn.
Default value: 0
=item iconMin HANDLE
Selects minimized button image in normal state.
=item iconMax HANDLE
Selects maximized button image in normal state.
=item iconClose HANDLE
Selects close button image in normal state.
=item iconRestore HANDLE
Selects restore button image in normal state.
=item iconMinPressed HANDLE
Selects minimize button image in pressed state.
=item iconMaxPressed HANDLE
Selects maximize button image in pressed state.
=item iconClosePressed HANDLE
Selects close button image in pressed state.
=item iconRestorePressed HANDLE
Selects restore button image in pressed state.
=item tileable BOOLEAN
Selects whether the window is allowed to participate in cascading and tiling
auto-arrangements, performed correspondingly by C<cascade> and C<tile> methods.
If 0, the window is never positioned automatically.
Default value: 1
=item titleHeight INTEGER
Selects height of the title bar in pixels. If 0, the default system
value is used.
Default value: 0
=item windowState STATE
A three-state property, that governs the state of a window.
STATE can be one of three C<ws::XXX> constants:
ws::Normal
ws::Minimized
ws::Maximized
The property can be changed
either by explicit set-mode call or by the user. In either case,
a C<WindowState> notification is triggered.
The property has three convenience wrappers: C<maximize()>, C<minimize()> and
C<restore()>.
Default value: C<ws::Normal>
See also: C<WindowState>

=item arrange_icons
Arranges geometrically the minimized sibling MDI windows.
=item cascade
Arranges sibling MDI windows so they form a cascade-like structure: the lowest
window is expanded to the full owner window inferior rectangle, window next to
the lowest occupies the inferior rectangle of the lowest window, etc.
Only windows with C<tileable> property set to 1 are processed.
=item client2frame X1, Y1, X2, Y2
Returns a rectangle that the window would occupy if
its client rectangle is assigned to X1, Y1, X2, Y2
rectangle.
=item frame2client X1, Y1, X2, Y2
Returns a rectangle that the window client would occupy if
the window rectangle is assigned to X1, Y1, X2, Y2
rectangle.
=item get_client_rect [ WIDTH, HEIGHT ]
Returns a rectangle in the window coordinate system that the client would
occupy if the window extensions are WIDTH and HEIGHT. If WIDTH and HEIGHT are
undefined, the current window size is used.
=item keyMove
Initiates window moving session, navigated by the keyboard.
=item keySize
Initiates window resizing session, navigated by the keyboard.
=item mdis
Returns array of sibling MDI windows.
=item maximize
Maximizes window. A shortcut for C<windowState(ws::Maximized)>.
=item minimize
Minimizes window. A shortcut for C<windowState(ws::Minimized)>.
=item post_action STRING
Posts an action to the windows; the action is deferred and executed in the next
message loop. This is used to avoid unnecessary state checks when the
action-executing code returns. The current implementation accepts following
string commands: C<min>, C<max>, C<restore>, C<close>.
=item repaint_title [ STRING = C<title> ]
Invalidates rectangle on the title bar, corresponding to STRING, which can be
one of the following:
left - redraw the menu button
right - redraw minimize, maximize, and close buttons
title - redraw the title
=item restore
Restores window to normal state from minimized or maximized state. A shortcut
for C<windowState(ws::Normal)>.
=item sizemove_cancel
Cancels active window moving or resizing session and returns the window to the
state before the session.
=item tile
Arranges sibling MDI windows so they form a grid-like structure, where all
windows occupy equal space, if possible.
Only windows with C<tileable> property set to 1 are processed.
=item xy2part X, Y
Maps a point in (X,Y) coordinates into a string, corresponding to a part of the
window: titlebar, button, or part of the border. The latter can be returned
only if C<borderStyle> is set to C<bs::Sizeable>. The possible return values
are:
border - window border; the window is not sizeable
client - client widget
caption - titlebar; the window is not moveable
title - titlebar; the window is movable
close - close button
min - minimize button
max - maximize button
restore - restore button
menu - menu button
desktop - the point does not belong to the window
In addition, if the window is sizeable, the following constants can be
returned, indicating part of the border:
SizeN - upper side
SizeS - lower side
SizeW - left side
SizeE - right side
SizeSW - lower left corner
SizeNW - upper left corner
SizeSE - lower right corner
SizeNE - upper right corner

=head2 Events
=over
=item Activate
Triggered when the user activates a window. Activation mark is usually resides
on a window that contains keyboard focus.
The module does not provide the activation function; C<select()> call is used
instead.
=item Deactivate
Triggered when the user deactivates a window. Window is usually marked
inactive, when it contains no keyboard focus.
The module does not provide the de-activation function; C<deselect()> call is
used instead.
=item WindowState STATE
Triggered when window state is changed, either by an explicit C<windowState()>
call, or by the user. STATE is the new window state, one of three C<ws::XXX>
constants.
=back
=head1 Prima::MDIMethods
=head2 Methods
The package contains several methods for a class that is to be used as a MDI
windows owner. It is enough to add class inheritance to C<Prima::MDIMethods> to
use the functionality. This step, however, is not required for a widget to
become a MDI windows owner; the package contains helper functions only, which
mostly mirror the arrangement functions of C<Prima::MDI> class.
=over
=item mdi_activate
Repaints window title in all children MDI windows.
=item mdis
Returns array of children MDI windows.
=item arrange_icons
Same as C<Prima::MDI::arrange_icons>.
=item cascade
Same as C<Prima::MDI::cascade>.
=item tile
Same as C<Prima::MDI::tile>.
