应用程序javafx的视图 [英] View of the application javafx

问题描述

我在谷歌搜索了几个小时，我仍然找不到合适的答案，所以我有机会来这里问。

i was searching in google for hours and i still cant find the right answer, so i have a last chance to come here and ask.

我正在制作学年JAVA FX项目。我正在使用NetBeans。

i'm making school year JAVA FX project. I'm using NetBeans.

我有一个观点，我可以在我的应用程序上看到。问题是：我想要一个大地图（背景），我需要能够随着我的观点移动。例如，向右移动50（x）。

I have a point that i can see on the application i have. The problem is: I would like to have a big map (background) and I need to be able to move with my view. For example move by 50 to the right (x).

我有应用程序，我使用Stage，Scene，StackPane。

I have Application where I use Stage, Scene, StackPane.

我听说过Java中的Dimensions，但我不能在javafx应用程序中使用它。是否有类似的东西，我可以在我的申请中使用什么？

I heard something about Dimensions in Java, but i can't use it in javafx application. Is there something similar, what can I use in my Application?

非常感谢。

推荐答案

我认为你要的是带有地图的场景（表示为图像）在背景和控件中分层放置在地图顶部，以允许在某些位置与地图进行交互。你的问题有点不清楚，所以我不确定这是不是你问的问题。

What I think you are asking for is a Scene with a map (represented as an Image) in the background and controls layered on top of the map to allow interaction with the map at certain positions. Your question is a little unclear, so I'm not exactly sure if that is what you are asking.

如果是这样，这里有一些示例代码来实现它。

If so, here is some sample code to implement that.

对于示例使用鼠标（或者可能是触摸命令或触控板滚动手势） - 虽然我没有触摸屏或触控板来测试它来拖动地图。点击按钮杀死邪恶的女巫。

For the example use the mouse (or probably touch commands or trackpad scroll gestures - though I haven't a touch screen or trackpad to test it) to drag the map around. Click on the button to "Kill the evil witch".

解决方案的工作原理是：

The solution works by:

1. 创建 ImageView 来保存背景地图。


2. 在 StackPane中构建场景内容叠加后台 ImageView 。


3. 在 ScrollPane中包装场景绑定到场景的大小。


4. 在 ScrollPane 上设置属性以使其可以平移。

1. Creating an ImageView to hold the background map.
2. Constructing the scene contents in a StackPane over the stacked background ImageView.
3. Wrapping the scene in a ScrollPane bound to the scene's size.
4. Setting properties on the ScrollPane to make it pannable.
