.SH DESCRIPTION
|
|
The
|
|
.ZN XAllocIconSize
|
|
function allocates and returns a pointer to a
|
|
.ZN XIconSize
|
|
structure.
|
|
Note that all fields in the
|
|
.ZN XIconSize
|
|
structure are initially set to zero.
|
|
If insufficient memory is available,
|
|
.ZN XAllocIconSize
|
|
returns NULL.
|
|
To free the memory allocated to this structure,
|
|
use
|
|
.ZN XFree .
|
|
.LP
|
|
.\" $Header: XSetISizes.d,v 1.2 88/06/11 07:53:16 mento Exp $
|
|
The
|
|
.ZN XSetIconSizes
|
|
function is used only by window managers to set the supported icon sizes.
|
|
.LP
|
|
.ZN XSetIconSizes
|
|
can generate
|
|
.ZN BadAlloc
|
|
and
|
|
.ZN BadWindow
|
|
errors.
|
|
.LP
|
|
.\" $Header: XGetISizes.d,v 1.2 88/06/11 07:51:07 mento Exp $
|
|
The
|
|
.ZN XGetIconSizes
|
|
function returns zero if a window manager has not set icon sizes;
|
|
otherwise, it return nonzero.
|
|
.ZN XGetIconSizes
|
|
should be called by an application that
|
|
wants to find out what icon sizes would be most appreciated by the
|
|
window manager under which the application is running.
|
|
The application
|
|
should then use
|
|
.ZN XSetWMHints
|
|
to supply the window manager with an icon pixmap or window in one of the
|
|
supported sizes.
|
|
To free the data allocated in size_list_return, use
|
|
.ZN XFree .
|
|
.LP
|
|
.ZN XGetIconSizes
|
|
can generate a
|
|
.ZN BadWindow
|
|
error.

.SH PROPERTIES
|
|
.TP 1i
|
|
\s-1WM_ICON_SIZES\s+1
|
|
The window manager may set this property on the root window to

|
specify the icon sizes it supports.
|
|
The C type of this property is
|
|
.ZN XIconSize .
|
|
.SH STRUCTURES
|
|
The
|
|
.ZN XIconSize
|
|
structure contains:

|
|
int width_inc, height_inc;
|
|
} XIconSize;
|
|
.De
|
|
.LP

|
The width_inc and height_inc members define an arithmetic progression of
|
|
sizes (minimum to maximum) that represent the supported icon sizes.
