Question

我有一个FlowPane洞察力TabPane。我如何将所有空间都放入TabPane？

这样做的可能方法是什么？

Answer 1

FlowPane会自动适应TabPane中的所有空格。请看下面的例子！如果你增加或减少场景的宽度，你实际上可以看到它是如何工作的！

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);
    }
}

将FlowPane自动调整为TabPane
