Question

我禁用了以下代码显示水平ScrollBar：

scrollPane.setHbarPolicy(ScrollPane.ScrollBarPolicy.NEVER);

它不再可见，但可以通过鼠标滚轮使用。我该如何防止这种情况？

有一个带有垂直ScrollBar的ScrollPane。但我可以点击鼠标滚轮到右边，内容滚动水平。

感谢。

Answer 1

hash1 = {"key1" =>["value1","value11"], "key2" => ["value2","value21"]} hash2= {"key3" => ["value3","value32"], "key4" => ["value4","value42"]} hash1.each do |k1,v1| hash2.each do |k2,v2| #do something with v1 and v2 (which are arrays themselves and get ["value1","value11"] and ["value3","value32"], then ["value1","value11"] and ["value4","value42"] in the first iteration of hash 1 and ["value2","value21"]and ["value3","value32"], then ["value2","value21"]and ["value4","value42"] in the second iteration of hash1 ) end end

Answer 2

编辑：使用this answer代替这个hacky

您可以使用ScrollEvent中的水平event filter：

    scrollPane.addEventFilter(ScrollEvent.SCROLL,new EventHandler<ScrollEvent>() {
        @Override
        public void handle(ScrollEvent event) {
            if (event.getDeltaX() != 0) {
                event.consume();
            }
        }
    });

Answer 3

我相信这是正确的方法：

sp.setHbarPolicy(ScrollPane.ScrollBarPolicy.NEVER);

如何在ScrollBar（JavaFX）中禁用水平滚动？
