将标签旋转90度会占用不必要的水平空间 [英] Rotating label 90 degrees takes up unnecessary horizontal space

问题描述

此问题基于 Javafx旋转标签问题，但由于此帖子已过时且没有令人满意的答案，我想再次提及.

This question is based on Javafx rotate Label issue, but because this post is outdated and has no satisfying answer, I would like to mention it again.

问题是:

将标签旋转90或270度时，首先，由于文本没有正确的最小宽度，因此文本被截断了.当我设置最小宽度时，文本不再被截断.

When rotating a label for 90 or 270 degrees, firstly the text is being truncated because it has not the right minimum width. When I set the minimum width, the text is not being truncated anymore.

但是，最小宽度也是在水平方向上设置的，如下所示:

However, the minimum width is also set in the horizontal direction, as shown below:

左边是Java 8u40的情况，右边是我喜欢的样子(这是我认为最合乎逻辑的方式).

On the left is the situation as it is now in Java 8u40, and on the right is how I like it to be (and which is the most logical way in my opinion).

我刚刚使用了以下代码:

I have just used this code:

Label label = new Label("This is a label.");
label.setRotate(270);
label.setMinWidth(200);

我已将标签添加到AnchorPane，这不是我的问题的一部分.我还尝试了@James_D解决方法( https://community.oracle.com/thread/3514254 )，这对我也不起作用.

I have added the label to a AnchorPane, which is not part of the problem I except. I also tried @James_D workaround (https://community.oracle.com/thread/3514254), which did not work for me either.

所以我的问题是:

这是一个已知的错误吗?如果是这样:将来是否有可能修复该错误?另外，是否有其他解决方法(除了将标签放置在图像中)?

Is this a known bug, and if so: is there any chance it will be fixed in the future? Also, is there another workaround possible (apart from placing the label in an image)?

推荐答案

在我看来，这是一个错误.我使用JavaFX应用程序进行了测试，该应用程序在Windows上旋转文本(运行Oracle JavaFX，JDK1.8.0.60j，然后将其移至RaspberryPi.Pi运行的是Open JavaFX.在Open JavaFX中，旋转正确执行，而Oracle JavaFX会显示您在此处描述的行为.

In my opinion it´s a bug. I did a test with a JavaFX app with rotating text on Windows (running Oracle JavaFX, JDK1.8.0.60j and then I moved it to Raspberry Pi. The Pi was running Open JavaFX. In Open JavaFX the rotation is performed correctly, while the Oracle JavaFX shows the behaviour you decribed here.
