自用的JavaFx轮子

一、窗体

0.class的创建

入口，比如login等，用Java application创建。其他用普通class

需要被调用的面板初始化：例如创建主页面MainPane

//新建的类extends AnchorPane
//以下都在该类里
private static MainPane mainPane;
private Stage stage;
//上面的适用于给别的类直接调用
private MainPane(){
    //基础配置。可能用try catch包起来
    
}
public Stage getStage(){
        return this.stage;
    }
 public static void showMainPane(String name){
        mainPane = new MainPane(name);
        mainPane.getStage().show();

    }//别的类要开面板就静态调用这个方法就行

0.5 可能需要的入口类。导出javafx application好像需要

新建一个类

public class StartApp {
    public static void main(String[] args) {
       Login.main(args);//login是打算的入口
    }
}

1.基础配置

 //设置fxml
FXMLLoader fx = new FXMLLoader();
AnchorPane root = (AnchorPane)fx.load(getClass().getClassLoader().getResource("login.fxml"));、
    //fxml拖到src下。
//设置scene
Scene scene = new Scene(root);
scene.setFill(null);//透明
stage.setScene(scene);
//窗体设置
stage.initStyle(StageStyle.TRANSPARENT);//透明
stage.setTitle("登录");

2.窗口拖拽

//坐标
private double oldStageX;
private double oldStageY;
private double oldScreenX;
private double oldScreenY;

//窗口拖拽

Pane dragPane = new Pane();
dragPane.setLayoutX(-1.0);
dragPane.setOpacity(0.0);
dragPane.setPrefHeight(41.0);
dragPane.setPrefWidth(236.0);
root.getChildren().add(dragPane);
dragPane.setOnMousePressed(new EventHandler<MouseEvent>() {
    @Override
    public void handle(MouseEvent event) {
        oldStageX = stage.getX();
        oldStageY = stage.getY();
        oldScreenX = event.getScreenX();
        oldScreenY = event.getScreenY();
    }
});
dragPane.setOnMouseDragged(new EventHandler<MouseEvent>() {
    @Override
    public void handle(MouseEvent event) {
        //新位置
        //拖拽前后的鼠标差值加上原始窗体坐标值
        stage.setX(event.getScreenX() - oldScreenX + oldStageX);
        stage.setY(event.getScreenY() - oldScreenY + oldStageY);
    }
});

3.关闭、最小化、最大化

//关闭按钮
Circle btn_close = new Circle();
btn_close.setLayoutX(25.0);
btn_close.setLayoutY(21.0);
btn_close.setRadius(7.0);
btn_close.setFill(Paint.valueOf("#ff481f"));
btn_close.setOnMouseClicked(new EventHandler<MouseEvent>() {
    @Override
    public void handle(MouseEvent event) {
        stage.close();
    }
});
root.getChildren().add(btn_close);

//最小化按钮
Circle btn_minimize = new Circle();
btn_minimize.setLayoutX(45.0);
btn_minimize.setLayoutY(21.0);
btn_minimize.setRadius(7.0);
btn_minimize.setFill(Paint.valueOf("orange"));
btn_minimize.setOnMouseClicked(new EventHandler<MouseEvent>() {
    @Override
    public void handle(MouseEvent event) {
        stage.setIconified(true);
    }
});
root.getChildren().add(btn_minimize);

最大化同理。

二、防止线程阻塞 好东西！

这是个好东西 多次救我 比如按回车后即使clear也会回车的问题。

Task<Void> recieveServertask = new Task<Void>() {
    @Override public Void call() {
        //···
        Platform.runLater(() -> {
            //在runlater里开防止连接时页面被阻塞
        });
        return null;
    }
};
new Thread(recieveServertask).start();

三、导出exe 烦

1.建议用jdk1.8（java 8）。再新就导不出exe了。Oracle真的太过分啦！（

2.

png 转 ico http://pic.55.la/png2ico/

不要忘记

1.stage.show();

2.层次顺序，先创建的再下。

3.如果是较新的java，每个ui类都要配置vmoption

普通页面创建模板 直接改就行
