JavaFX TabPane cancel tab change

Question

Using JavaFX 2.2 I have a window which consists mainly of a TabPane with 4 Tabs. The user may make changes to data presented in any of the tabs, and if they do, I want to make sure they don't loeave that tab until they've saved/cancelled/updated the data. In particular I want to make sure they don't select a different tab. I can catch if they're trying to quit or execute some menu item, but I can't seem to find a way to interrupt a tab change. I can catch when they've clicked on a new tab (onSelectionChanged), and ask if they really want to discard their edits, but then the tab change happens anyway. Help greatly appreciated.

Answer 1

获取选项卡窗格的选择模型，监视其选定的索引属性以进行更改，并在检测到更改时询问您的选项卡是否可以立即更改 - 如果没有，请将所选索引设置回当前选定的选项卡，覆盖选择更改为新选项卡。

您可以停用其他标签，直到用户点击“保存”或“取消”
