.SH DESCRIPTION
|
|
The
|
|
.ZN XtGetGC
|
|
function returns a sharable, read-only GC.
|
|
The parameters to this function are the same as those for
|
|
.ZN XCreateGC
|
|
except that a widget is passed instead of a display.
|
|
.ZN XtGetGC
|
|
shares only GCs in which all values in the GC returned by
|
|
.ZN XCreateGC
|
|
are the same.
|
|
In particular, it does not use the value_mask provided to
|
|
determine which fields of the GC a widget considers relevant.
|
|
The value_mask is used only to tell the server which fields should be
|
|
filled in with widget data and which it should fill in with default values.
|
|
For further information about value_mask and values,
|
|
see
|
|
.ZN XCreateGC
|
|
in the \fI\*(xL\fP.
|
|
.LP
|
|
The
|
|
.ZN XtReleaseGC
|
|
function deallocate the specified shared GC.
