示例#1

文件： cairo.go 项目： raichu/gotk3

// GetGroupTarget is a wrapper around cairo_get_group_target().
func (v *Context) GetGroupTarget() *Surface {
	c := C.cairo_get_group_target(v.native())
	s := wrapSurface(c)
	s.reference()
	runtime.SetFinalizer(s, (*Surface).destroy)
	return s
}

示例#2

文件： cairo.go 项目： jimmyfrasche/cairo

//GroupTarget returns the current destination surface for c.
//If there have been no calls to PushGroup/PushGroupWithContent,
//this is equivalent to Target.
//Otherwise,
//Originally cairo_get_group_target.
func (c *Context) GroupTarget() (Surface, error) {
	s := C.cairo_get_group_target(c.c)
	s = C.cairo_surface_reference(s)
	return XtensionRevivifySurface(s)
