Specifies the connection to the X server.
|
|
.IP \fIw\fP 1i
|
|
Specifies the window.

|
|
.SH DESCRIPTION
|
|
The
|
|
.ZN XAllocWMHints
|
|
function allocates and returns a pointer to a
|
|
.ZN XWMHints
|
|
structure.
|
|
Note that all fields in the
|
|
.ZN XWMHints
|
|
structure are initially set to zero.
|
|
If insufficient memory is available,
|
|
.ZN XAllocWMHints
|
|
returns NULL.
|
|
To free the memory allocated to this structure,
|
|
use
|
|
.ZN XFree .
|
|
.LP
|
|
The
|
|
.ZN XSetWMHints
|
|
function sets the window manager hints that include icon information and location,
|
|
the initial state of the window, and whether the application relies on the
|
|
window manager to get keyboard input.
|
|
.LP
|
|
.ZN XSetWMHints
|
|
can generate
|
|
.ZN BadAlloc
|
|
and
|
|
.ZN BadWindow
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XGetWMHints
|
|
function reads the window manager hints and
|
|
returns NULL if no WM_HINTS property was set on the window
|
|
or returns a pointer to a
|
|
.ZN XWMHints
|
|
structure if it succeeds.
|
|
When finished with the data,
|
|
free the space used for it by calling
|
|
.ZN XFree .
|
|
.LP
|
|
.ZN XGetWMHints
|
|
can generate a
|
|
.ZN BadWindow
|
|
error.

The input member is used to communicate to the window manager the input focus
|
|
model used by the application.
|
|
Applications that expect input but never explicitly set focus to any
|
|
of their subwindows (that is, use the push model of focus management),
|
|
such as X Version 10 style applications that use real-estate
|
|
driven focus, should set this member to
|
|
.ZN True .
|
|
Similarly, applications
|
|
that set input focus to their subwindows only when it is given to their
|
|
top-level window by a window manager should also set this member to
|
|
.ZN True .
|
|
Applications that manage their own input focus by explicitly setting
|
|
focus to one of their subwindows whenever they want keyboard input
|
|
(that is, use the pull model of focus management) should set this member to
|
|
.ZN False .
|
|
Applications that never expect any keyboard input also should set this member
|
|
to
|
|
.ZN False .
|
|
.LP
|
|
Pull model window managers should make it possible for push model
|
|
applications to get input by setting input focus to the top-level windows of
|
|
applications whose input member is
|
|
.ZN True .
|
|
Push model window managers should
|
|
make sure that pull model applications do not break them
|
|
by resetting input focus to
|
|
.ZN PointerRoot
|
|
when it is appropriate (for example, whenever an application whose
|
|
input member is
|
|
.ZN False
|
|
sets input focus to one of its subwindows).

The icon_mask specifies which pixels of the icon_pixmap should be used as the
|
|
icon.
|
|
This allows for nonrectangular icons.
|
|
Both icon_pixmap and icon_mask must be bitmaps.
|
|
The icon_window lets an application provide a window for use as an icon
|
|
for window managers that support such use.
|
|
The window_group lets you specify that this window belongs to a group
|
|
of other windows.
|
|
For example, if a single application manipulates multiple
|
|
top-level windows, this allows you to provide enough
|
|
information that a window manager can iconify all of the windows
|
|
rather than just the one window.
|
|
.LP
|
|
The
|
|
.ZN UrgencyHint
|
|
flag, if set in the flags field, indicates that the client deems the window
|
|
contents to be urgent, requiring the timely response of the user. The
|
|
window manager will make some effort to draw the user's attention to this
|
|
window while this flag is set. The client must provide some means by which the
|
|
user can cause the urgency flag to be cleared (either mitigating
|
|
the condition that made the window urgent or merely shutting off the alarm)
|
|
or the window to be withdrawn.
