XtGetGC(3Xt) XtGetGC(3Xt)
NAME
XtGetGC, XtReleaseGC - obtain and destroy a sharable GC
SYNOPSIS
GC XtGetGC(w, value_mask, values)
Widget w;
XtGCMask value_mask;
XGCValues *values;
void XtReleaseGC(w, gc)
Widget w;
GC gc;
ARGUMENTS
gc Specifies the GC to be deallocated.
values Specifies the actual values for this GC.
value_mask
Specifies which fields of the values are
specified.
w Specifies the widget.
DESCRIPTION
The XtGetGC function returns a sharable, read-only GC.
The parameters to this function are the same as those
for XCreateGC except that a widget is passed instead of
a display. XtGetGC shares only GCs in which all values
in the GC returned by 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 XCreateGC in the Xlib Programming Manual.
The XtReleaseGC function deallocates the specified
shared GC.
