示例1: apply
# 需要导入模块: from tree import Tree [as 别名]
# 或者: from tree.Tree import _navigate_to_index_parent [as 别名]
def apply(self, value_root):
source_parent = Tree._navigate_to_index_parent(self._index, value_root)
moved_node = source_parent.pop_child(self._index[-1])
dest_parent = Tree._navigate_to_index_parent(
self._dest_index,
value_root)
dest_parent.insert_child(self._dest_index[-1], moved_node)
event = self.Event(source_parent, moved_node)
source_parent.trigger_event(event)示例2: apply
# 需要导入模块: from tree import Tree [as 别名]
# 或者: from tree.Tree import _navigate_to_index_parent [as 别名]
def apply(self, value_root):
class Pair:
pass
remove_pairs = []
# build a pointer-based deletion reference so sibling's can't screw with
# eachother's indicies
for index in self._index_list:
pair = Pair()
pair.parent = Tree._navigate_to_index_parent(index, value_root)
pair.child = pair.parent.get_child(index[-1])
remove_pairs.append(pair)
for pair in remove_pairs:
pair.parent.remove_child(pair.child)
pair.parent.trigger_event(self.Event(pair.child))示例3: apply
# 需要导入模块: from tree import Tree [as 别名]
# 或者: from tree.Tree import _navigate_to_index_parent [as 别名]
def apply(self, value_root):
parent_node = Tree._navigate_to_index_parent(self._index, value_root)
