>This SHOULD be set by the Client before mapping, to a list of atoms indicating
the functional type of the window.  This property SHOULD be used by the window
manager in determining the decoration, stacking position and other behaviour
of the window.  The Client SHOULD specify window types in order of preference
(the first being most preferable), but MUST include at least one of the basic
window type atoms from the list below.  This is to allow for extension of the
list of types, whilst providing default behaviour for window managers that do
not recognise the extensions.  
	</P
><P
>Rationale:  This hint is intend to tqreplace the MOTIF hints.  One of the
objections to the MOTIF hints is that they are a purely visual description of
the window decoration.  By describing the function of the window, the window
manager can apply consistent decoration and behaviour to windows of the same
type.  Possible examples of behaviour include keeping dock/panels on top or
allowing pinnable menus / toolbars to only be hidden when another window has
focus (NextStep style).

a palette or toolbox. It is distinct from type TOOLBAR because it does not
correspond to a toolbar torn off from the main application. It's distinct from

open while they're working. Windows of this type may set the WM_TRANSIENT_FOR

>_NET_WM_STATE_MODAL indicates that this is a modal dialog box.  The
WM_TRANSIENT_FOR hint MUST be set to indicate which window the dialog is a
modal for, or set to the root window if the dialog is a modal for its window
group.

window's position fixed on the screen, even when the virtual desktop scrolls.

>_NET_WM_STATE_SKIP_TASKBAR indicates that the window should not be
included on a taskbar. This hint should be requested by the
application, i.e. it indicates that the window by nature is never
in the taskbar.  Applications should not set this hint if
_NET_WM_WINDOW_TYPE already conveys the exact nature of the
window.

included on a Pager. This hint should be requested by the application,

Pager. Applications should not set this hint if _NET_WM_WINDOW_TYPE
already conveys the exact nature of the window.
	</P
><P
>_NET_WM_STATE_HIDDEN should be set by the window manager to indicate
that a window would not be visible on the screen if its
desktop/viewport were active and its coordinates were within the
screen bounds. The canonical example is that minimized windows should
be in the _NET_WM_STATE_HIDDEN state.  Pagers and similar applications
should use _NET_WM_STATE_HIDDEN instead of WM_STATE to decide whether
to display a window in miniature representations of the windows on a
desktop.

>The purpose of struts is to reserve space at the borders of the desktop.  This
is very useful for a docking area, a taskbar or a panel, for instance.  The
window manager should know about this reserved space in order to be able to
preserve the space. Also maximized windows should not cover that reserved
space.

auto-hide panels.

A "corner" panel that does not extend for the full length of a screen border
SHOULD only set one strut.
