XtGetGC(3) XT FUNCTIONS XtGetGC(3)

NAME

XtGetGC, XtReleaseGC - obtain and destroy a sharable GC

SYNTAX

GC XtGetGC(Widget w, XtGCMask value_mask, XGCValues *values);

void XtReleaseGC(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 - C Language X Interface.

The XtReleaseGC function deallocate the specified shared GC.
