JavaFX - How to change TableView color of selected unfocused row?
提问by Markus Paul
No matter what i do - the color of the row keeps unchanged and has a greyish color. The changes only work for when the TableView is in focus.
无论我做什么 - 行的颜色保持不变并且呈灰色。这些更改仅适用于 TableView 处于焦点时。
I have tried every other suggestion i found online, for example a solution from another thread:
我已经尝试了我在网上找到的所有其他建议，例如来自另一个线程的解决方案：
.table-row-cell:selected { -fx-background-color: red; }
.table-row-cell:selected { -fx-background-color: red; }
Nothing seems to work and affect the rows when not in focus.
当不聚焦时，似乎没有任何工作并影响行。

Problem
问题
You want to change the color of the selection bar for a focused and unfocused state of TableView
您想为 TableView 的聚焦和非聚焦状态更改选择栏的颜色
Solution
解决方案
There is a -fx-selection-barand -fx-selection-bar-non-focuseddefinition in modena.css(default JavaFX style sheet). Both of them are in a section called Theming. So they are meant to be part of a changeable "global" theme. If you change them for the whole application, it will not only change the way TableView will color the selection, it will change even Menu's, List's etc. So you should be aware of it.
在modena.css（默认 JavaFX 样式表）中有一个-fx-selection-barand-fx-selection-bar-non-focused定义。它们都在名为Theming的部分中。因此，它们旨在成为多变的“全球”主题的一部分。如果你为整个应用程序改变它们，它不仅会改变 TableView 为选择着色的方式，它甚至会改变菜单、列表等。所以你应该意识到这一点。
But from your comments above it should be clear, that you try to add the style by calling the method .setStyle() on the TableView instance. If you doing that, changing the color by this boths attributes will result in changing only the color of the TableView selection bar.
但是从您上面的评论中可以清楚地看出，您尝试通过在 TableView 实例上调用 .setStyle() 方法来添加样式。如果这样做，通过这两个属性更改颜色将导致仅更改 TableView 选择栏的颜色。
