在JavaFX中显示禁用控件上的工具提示
可以在禁用的控件上显示工具提示吗？
It is possible to show a Tooltip on a disabled Control?
我有以下代码，但这不起作用：
I have the following code and this doesn't work:
txt_searchText.setDisable(true);
txt.searchText.setTooltip(new Tooltip("Message"));
有没有人能解决这个问题？
Has anyone a solution for that problem?
Thx
答案是否定的。目前您无法在禁用的节点上显示工具提示，原因很简单，禁用的节点不会收到任何MouseEvents。
The answer is no. Currently you cannot show a tooltip on disabled Node, for the simple reason that disabled Nodes do not receive any MouseEvents.

您的问题的一个解决方案可能是将您的Control包装成其他内容。
One solution to your problem could be to wrap your Control into something else.
例如，put您可以控制另一个Control，例如SplitPane或Label。然后，您可以将工具提示应用于该包装并禁用您的第一个控件。
For example, put your control into another Control, like a SplitPane or a Label. Then you could apply your tooltip to that wrapper and disable your first control.
