[英]The width of button using default modena styles in JavaFX
Take a look at the following image: 看一下下面的图片:
There are two elements on it - Button
and Label
with the same text. 上面有两个元素-
Button
和带有相同文本的Label
。
Button has width 54 px
, lable has width 36 px
. 按钮的宽度为
54 px
,标签的宽度为36 px
。 The difference is: 54px - 36px = 18px
. 区别是:
54px - 36px = 18px
。
I've studied modena.css but
still can't understand where these 18px
come from. 我已经研究过
modena.css but
仍然不知道这18px
来自何处。
Could anyone explain? 谁能解释?
In the current version of modena.css , line 420, button has padding defined by 在当前版本的modena.css的第420行中,按钮具有由以下内容定义的填充:
-fx-padding: 0.333333em 0.666667em 0.333333em 0.666667em; /* 4 8 4 8 */
On windows, 0.6666667em
is 8 pixels, on a Mac it is slightly more, so that padding on the left and right sides accounts for the difference in width. 在Windows上,
0.6666667em
是8像素,在Mac上,则稍高一些,因此左侧和右侧的填充说明了宽度的差异。
