However, changing the tab makes the TabPane realize that it is too small and resize. Below is a small

CheckBoxTreeItem<String> rootItem = new CheckBoxTreeItem<>

问题 I have a requirement similar to this example. In the EventHandler callback, how do I determine which row was clicked on? @Override public void handle(ActionEvent event) { // how do I get the row details when reusing context menu and handler code? } I am sharing the context menu because I have to add a CheckMenuItem who's state is "global" to the table, i.e. if its selected on any row, I want to show it as checked when I click on any other row in the table. 回答1: Use a row factory and one

Shape.intersect produces a perfect shape, but it is translated / moved a bit and I can't figure out how much to put it back. Ideally, I'd like to have the intersection area occur exactly where the two original shapes intersect - i.e. the new intersection would fit
