JavaFX基础

 设置一个场景

package application;
	
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;


public class Myjava extends Application {
	@Override
	//重写
	public void start(Stage primaryStage) {
		Button btOK = new Button("OK");
		//创键一个OK按钮
		Scene scene = new Scene(btOK,300,450);
		//将按钮放入场景中并设置场景大小
		primaryStage.setTitle("MyjavaFX");
		//设置舞台标题
		primaryStage.setScene(scene);
		//将场景放入舞台
		primaryStage.show(); 
		//展示舞台
		
		
	}
	
	public static void main(String[] args) {
		launch(args);
	}
}

 

 同时设置两个场景

package application;
	
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;


public class Myjava extends Application {
	@Override
	//重写
	public void start(Stage primaryStage) {
		
		Scene scene = new Scene((new Button("OK")),300,450);
		//将按钮放入场景中并设置场景大小
		primaryStage.setTitle("MyjavaFX");
		//设置舞台标题
		primaryStage.setScene(scene);
		//将场景放入舞台
		primaryStage.show(); 
		//展示舞台
		
		Stage stage = new Stage();
		stage.setTitle("Second Stage");
		//设置场景标题
		stage.setScene(new Scene(new Button("new Stage"),300,450));
		//在舞台总设置一个带有按钮的场景
		stage.show();
		//展示舞台
		
	}
	
}

 

 

 将按钮置于面板中

package application;
	
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
import javafx.scene.layout.StackPane;


public class Myjava extends Application {
	@Override
	//重写
	public void start(Stage primaryStage) {
		
		StackPane pane = new StackPane();
		//创建一个面板
		pane.getChildren().add(new Button("OK"));
		//在面板中添加按钮
		Scene scene = new Scene(pane,200,50);
		
		primaryStage.setTitle("Button in a pane");
		//设置标题
		primaryStage.setScene(scene);
		//将场景放入舞台中
		primaryStage.show();
		//展示舞台
		
	}
	
}

 

 在面板中央显示圆的比例

package application;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.scene.layout.Pane;
import javafx.scene.shape.Circle;
import javafx.scene.paint.Color;



public class Myjava extends Application {
	@Override
	//重写
	public void start(Stage primaryStage) {
		
		Circle circle = new Circle();
		circle.setCenterX(100);
		circle.setCenterY(100);
		//设置圆的中心位置
		circle.setRadius(50);
		//设置圆的半径
		circle.setStroke(Color.RED);
		//设置边缘的颜色
		circle.setFill(Color.YELLOW);
		//设置填充颜色
		
		Pane pane = new Pane();
		//
		pane.getChildren().add(circle);
		Scene scene = new Scene(pane,200,200);
		
		primaryStage.setTitle("ShowCircle");
		//设置标题
		primaryStage.setScene(scene);
		//将场景放入舞台中
		primaryStage.show();
		//展示舞台
		
	}
	
}

package application;
import javafx.application.Application;

import javafx.geometry.HPos;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;


public class Main extends Application {
	@Override
		public void start(Stage primaryStage) throws Exception {
			GridPane pane = new GridPane();
			pane.setAlignment(Pos.CENTER);
			pane.setPadding(new Insets(11.5,12.5, 13.5,14.5));
			pane.setHgap(5.5);
			pane.setVgap(5.5);
			
			pane.add(new Label("First Name"),0,0);
			pane.add(new TextField(),1,0);
			pane.add(new Label("MI:"),0,1);
			pane.add(new TextField(),1,1);
			pane.add(new Label("Last Name:"),0,2);
			pane.add(new TextField(),1,2);
			Button btAdd = new Button("Add Name");
			pane.add(btAdd,1,3);
			GridPane.setHalignment(btAdd,HPos.RIGHT);
			Scene scene = new Scene(pane);
			primaryStage.setTitle("ShowGridPane");
			primaryStage.setScene(scene);
			primaryStage.show();
		}
}
