但是此代码有效,请提供帮助。
But this code is working, please help.
推荐答案
您需要使用CSS样式表才能在按钮上启用删除线。无论如何,使用CSS样式表通常比使用内联CSS setStyle命令更为方便。
You need to use a CSS stylesheet to enable strikethrough on a button. Using a CSS stylesheet is usually preferable to using an inline CSS setStyle command anyway.
/** file: strikethrough.css (place in same directory as Strikeout) */
.button .text {
-fx-strikethrough: true;
}
CSS样式表使用CSS选择器选择按钮内的文本,然后对它应用删除线样式。当前(从Java 8开始),setStyle命令不能使用CSS选择器,因此您必须使用CSS样式表才能实现此功能(或使用内联查找,这是不可取的)-无论如何,样式表是最好的解决方案。
The CSS style sheet uses a CSS selector to select the text inside the button and apply a strikethrough style to it. Currently (as of Java 8), setStyle commands cannot use CSS selectors, so you must use a CSS stylesheet to achieve this functionality (or use inline lookups, which would not be advisable) - the style sheet is the best solution anyway.
请参阅@icza的答案,以了解为什么尝试直接在按钮上设置 -fx-strikethrough
样式无效的原因。
See @icza's answer to understand why trying to set the -fx-strikethrough
style directly on the button does not work.
这里是一个示例应用程序:
Here is a sample application:
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Strikeout extends Application {
@Override
public void start(Stage stage) throws Exception {
Button strikethrough = new Button("Strikethrough");
strikethrough.getStylesheets().addAll(getClass().getResource(
"strikethrough.css"
).toExternalForm());
StackPane layout = new StackPane(
strikethrough
);
layout.setPadding(new Insets(10));
stage.setScene(new Scene(layout));
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
