DMXChangeDesktopAttributes \- change global bounding box

|
.SH SYNOPSIS
|
|
.B #include <X11/extensions/dmxext.h>
|
|
.sp
|
|
.nf
|
|
.BI "int DMXChangeDesktopAttributes(Display " *dpy ,
|
|
.BI " unsigned int " mask ,
|
|
.BI " DMXDesktopAttributes " *attr );
|

|
|
.SH DESCRIPTION
|
|
.B DMXChangeDesktopAttributes()
|
|
resizes the bounding box of the whole screen when using the Xinerama
|
|
extension. Otherwise, it has no effect on the screen layout.
|
|
An attribute mask is placed in
|
|
.I mask
|
|
and the attributes to change are placed in
|
|
.IR attr .
|
|
.PP
|
|
The values that are used to compute
|
|
.I mask
|
|
are as follows:
|
|
.sp
|
|
.nf
|
|
DMXDesktopWidth
|
|
DMXDesktopHeight
|
|
DMXDesktopShiftX
|
|
DMXDesktopShiftY
|
|
.fi
|
|
.PP
|
|
The
|
|
.B DMXDesktopAttributes
|
|
structure is:
|
|
.sp
|
|
.nf
|
|
typedef struct {
|
|
unsigned int width;
|
|
unsigned int height;
|
|
int shiftX;
|
|
int shiftY;
|
|
} DMXDesktopAttributes;
|
|
.fi
|
|
.PP
|
|
.I width " and " height
|
|
specify the new width and height for the bounding box.
|
|
.I shiftX " and " shiftY
|
|
specify where the Xinerama origin will be placed with respect to the
|
|
origin of the new bounding box. This allows the left and upper edges of
|
|
the bounding box to be changed without changing the visual position of
|
|
the windows on the desktop. If
|
|
.I width " or " height
|
|
is not specified, the current values will be used. If
|
|
.I shiftX " or " shiftY
|
|
is not specified, 0 will be used.
|
|
.PP
|
|
All coordinants are in the global DMX coordinant system. If Xinerama is
|
|
not active, an error will be generated.
|
|
.SH "RETURN VALUE"
|
|
.B DMXChangeDesktopAttributes()
|
|
will return 0 on success,
|
|
.B DmxBadXinerama
|
|
if Xinerama is not active,
|
|
.B DmxBadValue
|
|
if the size of the bounding box is too large, and
|
|
.B DmxBadReply
|
|
if there was a protocol error.
|
|
.PP
|
|
.B DMXChangeDesktopAttributes()
|
|
can generate
|
|
.B BadLength
|
|
(if the request is malformed, which should never happen when using this
|
|
library interface), and
|
|
.B BadValue
|
|
(if any values are out of range).
