如何删除 JavaFX 按钮的默认边框发光(选中时)? [英] How do I remove the default border glow of a JavaFX button (when selected)?

问题描述

我正在尝试删除选择 JavaFX 按钮时默认出现的边框发光(请参见下面的屏幕截图):

I'm trying to remove the border glow (please see screenshot below) that appears by default when a JavaFX button is selected:

我也想使用 CSS 来做到这一点，而不是从主 JavaFX 脚本中声明.但是，我无法弄清楚我需要使用什么 CSS 属性(呃，设置为 0?)才能删除该边框.

I also want to do this using CSS, and not declaratively from within the main JavaFX script. However, I am having trouble figuring out what CSS property I need to use (er, set to 0?) in order to remove that border.

推荐答案

从代码中的任何控件中移除焦点环显示:

To remove the focus ring display from any control from within code:

control.setStyle("-fx-focus-color: transparent;");

要移除所有控件的焦点环，请应用样式表:

To remove the focus ring for all controls, apply a stylesheet:

.root { -fx-focus-color: transparent; }

要仅移除所有按钮的环，请使用:

To only remove the ring for all buttons, use:

.button { -fx-focus-color: transparent; }

我发现 -fx-focus-color 属性设置比依靠一些奇怪的插图组合来移除聚焦环更直接.

I find the -fx-focus-color attribute setting more straight-forward than relying on some weird combination of insets to remove the focus ring.

此外，您可以使用相同的设置将对焦环更改为不同的颜色，例如-fx-focus-color: firebrick.

In addition, you can use the same setting to change the focus ring to a different color, such as -fx-focus-color: firebrick.

JavaFX 8 附带一个新的默认用户代理样式表 (摩德纳).这个新的用户代理样式表附带了一个额外的焦点突出设置:-fx-faint-focus-color.对于 Java 8 应用程序，需要将 -fx-focus-color 和 -fx-faint-focus-color 都设置为透明以去除对焦环的所有痕迹.请参阅 good4m 对此问题的回答.

JavaFX 8 shipped with a new default user agent stylesheet (modena). This new user agent stylesheet shipped with an additional setting for focus highlights: -fx-faint-focus-color. For Java 8 applications, it is necessary to set both -fx-focus-color and -fx-faint-focus-color to transparent to remove all traces of the focus ring. See good4m's answer to this question.

如果您只按照本答案之前的建议将焦点颜色设置为透明，对于某些控件，您可能会看到控件聚焦和不聚焦之间的细微差别.对于许多应用程序来说，这不是问题，将焦点颜色设置为透明就足够了.

If you only set the focus colors to transparent as previously recommended in this answer, for some controls you may see some subtle differentiation between when a control is focused and when it is not. For many applications this will not be an issue and setting the focus colors to transparent will be sufficient.
