如何在JavaFX中设置滚动窗格的单位增量？ [英] How can I set the unit increment for a scroll pane in JavaFX?

问题描述

JavaFX中的 ScrollBar 类包含用于设置单位增量，这就是我所追求的 - 但我无法找到如何获得此ScrollBar，或者从ScrollPane 课程！我认为我必须遗漏一些明显的东西 - 我如何实现这一目标？

The ScrollBar class in JavaFX contains a property for setting the unit increment, which is what I'm after - however I can't find how to get at this ScrollBar, or set the unit increment some other way from the ScrollPane class! I presume I must be missing something obvious - how do I achieve this?

推荐答案

从技术上讲，你应该能够实现这一目标初始化外观后使用 .lookup（scrollbar）方法（如果滚动条可见）。我不喜欢那个答案。

Technically, you should be able to get to it using the .lookup("scrollbar") method after the skin is initialized (if the scrollbar is visible). I don't like that answer though.

根据这个错误罚单，我认为你没有遗漏任何东西：

I don't think you're missing anything according to this bug ticket:

我鼓励你跳过它，展示你的用例，投票，看看你是否可以在将来得到某种回应。

I'd encourage you to jump on that, present your use case, vote, and see if you can get some sort of response in the future.
