.SH DESCRIPTION
|
|
The
|
|
.ZN XAllocSizeHints
|
|
function allocates and returns a pointer to a
|
|
.ZN XSizeHints
|
|
structure.
|
|
Note that all fields in the
|
|
.ZN XSizeHints
|
|
structure are initially set to zero.
|
|
If insufficient memory is available,
|
|
.ZN XAllocSizeHints
|
|
returns NULL.
|
|
To free the memory allocated to this structure,
|
|
use
|
|
.ZN XFree .
|
|
.LP
|
|
The
|
|
.ZN XSetWMNormalHints
|
|
function replaces the size hints for the WM_NORMAL_HINTS property
|
|
on the specified window.
|
|
If the property does not already exist,
|
|
.ZN XSetWMNormalHints
|
|
sets the size hints for the WM_NORMAL_HINTS property on the specified window.
|
|
The property is stored with a type of WM_SIZE_HINTS and a format of 32.
|
|
.LP
|
|
.ZN XSetWMNormalHints
|
|
can generate
|
|
.ZN BadAlloc
|
|
and
|
|
.ZN BadWindow
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XGetWMNormalHints
|
|
function returns the size hints stored in the WM_NORMAL_HINTS property
|
|
on the specified window.
|
|
If the property is of type WM_SIZE_HINTS, is of format 32,
|
|
and is long enough to contain either an old (pre-ICCCM)
|
|
or new size hints structure,
|
|
.ZN XGetWMNormalHints
|
|
sets the various fields of the
|
|
.ZN XSizeHints
|
|
structure, sets the supplied_return argument to the list of fields
|
|
that were supplied by the user (whether or not they contained defined values),
|
|
and returns a nonzero status.
|
|
Otherwise, it returns a zero status.
|
|
.LP
|
|
If
|
|
.ZN XGetWMNormalHints
|
|
returns successfully and a pre-ICCCM size hints property is read,
|
|
the supplied_return argument will contain the following bits:

If the property is large enough to contain the base size
|
|
and window gravity fields as well,
|
|
the supplied_return argument will also contain the following bits:

The

on the named window.
|

sets the size hints for the specified property

on the named window.
|
|
The property is stored with a type of WM_SIZE_HINTS and a format of 32.

The

|
The x, y, width, and height members are now obsolete
|
|
and are left solely for compatibility reasons.
|
|
The min_width and min_height members specify the
|
|
minimum window size that still allows the application to be useful.
|
|
The max_width and max_height members specify the maximum window size.
|
|
The width_inc and height_inc members define an arithmetic progression of
|
|
sizes (minimum to maximum) into which the window prefers to be resized.
|
|
The min_aspect and max_aspect members are expressed
|
|
as ratios of x and y,
|
|
and they allow an application to specify the range of aspect
|
|
ratios it prefers.
|
|
The base_width and base_height members define the desired size of the window.
|
|
The window manager will interpret the position of the window
|
|
and its border width to position the point of the outer rectangle
|
|
of the overall window specified by the win_gravity member.
|
|
The outer rectangle of the window includes any borders or decorations
|
|
supplied by the window manager.
|
|
In other words,
|
|
if the window manager decides to place the window where the client asked,
|
|
the position on the parent window's border named by the win_gravity
|
|
will be placed where the client window would have been placed
|
|
in the absence of a window manager.
