点击按钮红点应该会闪烁

javafx java

Joe Mau · 技术社区 · 6 年前

我有一个fontawesomeicon。如果我按下按钮 btStar btStop 它应该被禁用。我试过贴标签。当我按下按钮btStart时,标签在一个时间间隔内随着 SetVisible(true) 和 setVisible(false) .

有人能给我一个解决办法吗?先谢谢你。主类

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

控制器.java

package sample;

import de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;

import java.awt.*;

public class Controller {

    @FXML
    private FontAwesomeIconView iconCamera;

    @FXML
    private Button btStart;

    @FXML
    private Button btStop;

    @FXML
    void mouseCklicked(ActionEvent event) {
        System.out.println("sad");

    }
}
