將FlowPane自動調整爲TabPane

Question

我有FlowPane洞察TabPane。我如何將所有的空間放入TabPane？

這樣做有什麼可能的方法？

Answer 1

FlowPane自動適合TabPane中的所有空間。請看下面的例子！如果您增加或減少場景的寬度，您實際上可以看到它的工作原理！

import javafx.application.Application; 
import javafx.geometry.Insets; 
import javafx.scene.Scene; 
import javafx.scene.control.Tab; 
import javafx.scene.control.TabPane; 
import javafx.scene.layout.FlowPane; 
import javafx.scene.layout.VBox; 
import javafx.scene.text.Font; 
import javafx.scene.text.FontWeight; 
import javafx.scene.text.Text; 
import javafx.stage.Stage; 

public class FlowPaneExample extends Application { 

    @Override 
    public void start(Stage primaryStage) { 
     VBox mockCalendar = new VBox(); 
     TabPane tabPane = new TabPane(); 
     Tab tab = new Tab("Month"); 
     tabPane.getTabs().add(tab); 
     FlowPane header = new FlowPane(); 

     //pad the header text objects on the top and bottom 
     header.setPadding(new Insets(5, 0, 5, 0)); 

     //Set the vetical and horizontal gap between text objects 
     header.setVgap(3); 
     header.setHgap(3); 


     //Creates a series of Text objects to file the top FlowPane 
     Text monDay = new Text("Mon"); 
     monDay.setFont(Font.font("Arial", FontWeight.BOLD, 20)); 

     Text tueDay = new Text("Tue"); 
     tueDay.setFont(Font.font("Arial", FontWeight.BOLD, 20)); 

     Text wedDay = new Text("Wed"); 
     wedDay.setFont(Font.font("Arial", FontWeight.BOLD, 20)); 

     Text thuDay = new Text("Thu"); 
     thuDay.setFont(Font.font("Arial", FontWeight.BOLD, 20)); 

     Text friDay = new Text("Fri"); 
     friDay.setFont(Font.font("Arial", FontWeight.BOLD, 20)); 

     Text satDay = new Text("Sat"); 
     satDay.setFont(Font.font("Arial", FontWeight.BOLD, 20)); 

     Text sunDay = new Text("Sun"); 
     sunDay.setFont(Font.font("Arial", FontWeight.BOLD, 20)); 

     //Add the Text objects as children to the FlowPane 
     header.getChildren().add(monDay); 
     header.getChildren().add(tueDay); 
     header.getChildren().add(wedDay); 
     header.getChildren().add(thuDay); 
     header.getChildren().add(friDay); 
     header.getChildren().add(satDay); 
     header.getChildren().add(sunDay); 

     FlowPane content = new FlowPane(); 

     //pad the text objects to match the header FlowPane 
     content.setPadding(new Insets(5, 5, 5, 5)); 

     //Set the vetical and horizontal gap between text objects 
     content.setVgap(10); 
     content.setHgap(25); 

     //Set the content of the second FlowPane using text objects created from 
     //the string array 
     for (int i = 0; i<33; i++) 
     { 
      String[] days = {" " , " " , " 1" , " 2" , " 3" , 
        " 4" , " 5" , " 6" , 
        " 7" , " 8" , " 9" , "10" , "11" , "12" , 
        "13" , "14" , "15" , "16" , "17" , "18" , 
        "19" , "20" , "21", "22" , "23" , "24" , 
        "25" , "26" , "27" , "28" , "29" , "30" , "31"}; 
      content.getChildren().add(new Text(days[i])); 

     } 

     //Add the two FlowPane objects to the VBox 

     mockCalendar.getChildren().add(header); 
     mockCalendar.getChildren().add(content); 
     tab.setContent(mockCalendar); 

     //Use the Vbox as the root node of the Scene 
     Scene scene = new Scene(tabPane, 280, 300); 

     primaryStage.setTitle("FlowPane Example Program"); 
     primaryStage.setScene(scene); 
     primaryStage.show(); 
    } 

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