You are looking for the disableProperty:

定义此节点的各个禁用状态.将禁用设置为true将导致此节点和所有子节点被禁用.这属性应仅用于设置节点的禁用状态.为了查询节点的禁用状态，disabled属性应而是使用它，因为有可能某个节点被禁用为祖先被禁用的结果，即使个人禁用该节点上的状态为false.

Defines the individual disabled state of this Node. Setting disable to true will cause this Node and any subnodes to become disabled. This property should be used only to set the disabled state of a Node. For querying the disabled state of a Node, the disabled property should instead be used, since it is possible that a Node was disabled as a result of an ancestor being disabled even if the individual disable state on this Node is false.

setDisable(true); // will disable the Button
setDisable(false); // will enable it again
