我正在尝试为我的GridPane设置填充,但每次设置填充时它都会给出错误消息:
incompatible types: java.awt.Insets cannot be converted to javafx.geometry.insets
我去的每个网站和每个搜索都声明如下所示:
grid.setPadding(new Insets(10, 10, 10, 10));
在我的代码中,我将它设置为完全相同,仅用于测试目的:
grid.setPadding(new Insets(10, 10, 10, 10));
所以我不明白为什么它不允许我写这个,我也试图研究错误信息,但没有任何结果。
这是我的代码:

答案 0 :(得分:4)
错误消息告诉您需要知道的一切:
不兼容的类型:java.awt.Insets无法转换为javafx.geometry.insets
您已导入java.awt.Insets
:(代码中的第一个导入行),您需要javafx.geometry.Insets
。
答案 1 :(得分:-1)
上面的答案很好。你需要
elevation
代替
import javafx.geometry.Insets;
当我允许 IDE 自动导入必要的库时,我第一次生成了错误。有时捷径会咬人。
