Is there anyway to make a Label text selectable in JavaFx8? I know, there are other simple workaround like using a TextField. But my label needs multiline text with wrapping facility which TextField does not provide. If I use TextArea, the problem is I can't shrink the TextArea based on the text's size like a Label. So I can't use either of them.
在JavaFx8中是否有标签文本可选?我知道,还有其他简单的方法,比如使用TextField。但是我的标签需要多行文本以及文本域不提供的包装功能。如果我使用TextArea,问题是我不能像标签一样根据文本的大小缩小文本区域。所以这两个都不能用。
Also my use of label text is like below:
我对标签文本的使用如下:
<VBox>
<Label wrapText="true"
VBox.vgrow="ALWAYS"
maxHeight="Infinity" minHeight="-Infinity"
text="Some Random Subject Line With Very Large Text To Test The Wrap Text, Lorem Ipsum Dolor"/>
</VBox>
Depending on the VBox width, Label's height resizes to fit the text fully. I can't emulate this kind of behaviour using either TextArea or TextField. But I need to be able to select the text from Label. Any ideas?
根据VBox的宽度,标签的高度调整大小以适合文本。我不能使用TextArea或TextField来模拟这种行为。但是我需要能够从标签中选择文本。什么好主意吗?

Here is a workaround until someone post something better.
这里有一个变通方案,直到有人发布更好的东西。
If you double click the label it changes to a TextArea. You can then copy the text. Once you press enter on the TextArea it changes back to the label.
如果你双击标签,它会更改为一个TextArea。然后可以复制文本。当你按下文本区域的enter时,它就会回到标签。
