Golang g_object_class_find_property Examples

Example #1

File: glib.go Project: yamnikov-oleg/gotk3

// GetPropertyType returns the Type of a property of the underlying GObject.
// If the property is missing it will return TYPE_INVALID and an error.
func (v *Object) GetPropertyType(name string) (Type, error) {
	cstr := C.CString(name)
	defer C.free(unsafe.Pointer(cstr))

	paramSpec := C.g_object_class_find_property(C._g_object_get_class(v.native()), (*C.gchar)(cstr))
	if paramSpec == nil {
		return TYPE_INVALID, errors.New("couldn't find Property")
	}
	return Type(paramSpec.value_type), nil
}

Example #2

File: gobject.go Project: napsy/go-gtk3

func FindProperty(obj ObjectLike, propName string) *GParamSpec {
	cpn := GString(propName)
	defer cpn.Free()

	oc := C.get_object_class(obj.ToNative())
	pspec := C.g_object_class_find_property(oc, (*C.gchar)(cpn.GetPtr()))
	if pspec == nil {
		return nil
	}
	gpspec := GParamSpec{pspec}
	return &gpspec
