NAME
XSetState, XSetFunction, XSetPlaneMask, XSetForeground, XSetBackground
- GC convenience routines
SYNTAX
int XSetState(Display *display, GC gc, unsigned long foreground,
unsigned int background, int function, unsigned long
plane_mask);
int XSetFunction(Display *display, GC gc, int function);
int XSetPlaneMask(Display *display, GC gc, unsigned long plane_mask);
int XSetForeground(Display *display, GC gc, unsigned long foreground);
int XSetBackground(Display *display, GC gc, unsigned long background);
ARGUMENTS
background
Specifies the background you want to set for the specified
GC.
display Specifies the connection to the X server.
foreground
Specifies the foreground you want to set for the specified
GC.
function Specifies the function you want to set for the specified GC.
gc Specifies the GC.
plane_mask
Specifies the plane mask.
DESCRIPTION
The XSetState function sets the foreground, background, plane mask, and
function components for the specified GC.
XSetState can generate BadAlloc, BadGC, and BadValue errors.
XSetFunction sets a specified value in the specified GC.
XSetFunction can generate BadAlloc, BadGC, and BadValue errors.
The XSetPlaneMask function sets the plane mask in the specified GC.
XSetPlaneMask can generate BadAlloc and BadGC errors.
The XSetForeground function sets the foreground in the specified GC.
XSetForeground can generate BadAlloc and BadGC errors.
The XSetBackground function sets the background in the specified GC.
XSetBackground can generate BadAlloc and BadGC errors.
DIAGNOSTICS
BadAlloc The server failed to allocate the requested resource or
server memory.
BadGC A value for a GContext argument does not name a defined
GContext.
BadValue Some numeric value falls outside the range of values accepted
by the request. Unless a specific range is specified for an
argument, the full range defined by the argument’s type is
accepted. Any argument defined as a set of alternatives can
generate this error.
