从我的程序中我收到此错误: Eclipse console output
我想做的就是使用按钮上的悬停效果将文本变成白色。 这是我的代码: Main.java:
import java.util.Date;
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.control.TableView;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.Pane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
Pane mainPane = (Pane) FXMLLoader.load(Main.class.getResource("Main.fxml"));
primaryStage.setScene(new Scene(mainPane));
primaryStage.show();
}
}
这是我的 Main.fxml 文件:

最后这是我的 myStyle.css 文件:
@charset "ISO-8859-1";
.button:hover{
-fx-text-fill: #fffff;
}
到目前为止,我只有一个月的时间来编程,所以请不要批评我的代码或我容易犯的错误。提前感谢您帮助解决问题,我使用场景生成器和 CSS 样式表不到一天,但我需要快速取得进展,因为我已经有近 5 年没有像今年剩下的时间那样编程了。
最佳答案
JavaFX CSS 不支持完整的 CSS 规范;只是其中的一个子集。特别是唯一的“@-Rules”listed as supported是 @import
和 @font-face
。因此,第一行的 @charset
规则不受支持。
删除 CSS 文件的第一行(包含 @charset
)将使 CSS 文件能够被解析。
此外,您还说过希望文本在悬停时变成白色:您需要 #ffffff
(六个“f
”);你有#fffff
(只有五个“f
”)。
关于java - CSS 解析文件 JavaFX 时出错,但我不知道出了什么问题,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/46932089/
