JComponents 的 2D 网格 (Swing)

发布于 2025-01-07 13:47:00 字数 543 浏览 5 评论 0原文

我正在尝试制作 JTextFields 的 2D 网格来表示级别图。我已经完成以下初始化 TextFields 的 2D 数组的操作：

fields = new TextField[level.rows][level.columns];
TextField field;
    for (int r = 0; r < level.rows; r++) {
        for (int c = 0; c < level.columns; c++) {
            field = new TextField(level.bricks[r][c].type);
            fields[r][c] = field;
        }

现在我必须将它们添加到 JFrame 中，但它们需要对齐，以便每个行 都位于另一列下方。我确实找到了 GridLayout，但是我对 AWT/Swing 不太有经验，并且仍然不知道如何实现所需的布局。我期待有某种类似 gLayout.add(JComponent,row,column) 的方法。

I'm trying to make a 2D grid of JTextFields to represent a level map. I've come to the following for initializing the 2D Array of TextFields:

fields = new TextField[level.rows][level.columns];
TextField field;
    for (int r = 0; r < level.rows; r++) {
        for (int c = 0; c < level.columns; c++) {
            field = new TextField(level.bricks[r][c].type);
            fields[r][c] = field;
        }

Now I have to add them to the JFrame, but they need to be lined up so that every row gets under the other column. I did find GridLayout, however i'm not very experienced with AWT/Swing, and still don't know how achieve the desired layout. I was expecting there to be some kind of method like gLayout.add(JComponent,row,column).

这应该像您所解释的那样工作，这是一个完整的工作示例，将 JLabels 放入 5x5 网格中：

import java.awt.*;
import javax.swing.*;

public class GridPrb {
  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    Container cp = frame.getContentPane();
    cp.setLayout(new GridLayout(5, 5));

    for(int y = 0; y < 5; y++) {
      for(int x = 0; x < 5; x++) {
        Label l = new Label("x=" + x + ",y=" + y);
        cp.add(l);
      }
    }
    frame.pack();
    frame.setVisible(true);
  }
}

最终结果如下所示：

希望这会有所帮助。

This should work as you explained, here's a fully working example that puts JLabels in the 5x5 Grid:

import java.awt.*;
import javax.swing.*;

public class GridPrb {
  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    Container cp = frame.getContentPane();
    cp.setLayout(new GridLayout(5, 5));

    for(int y = 0; y < 5; y++) {
      for(int x = 0; x < 5; x++) {
        Label l = new Label("x=" + x + ",y=" + y);
        cp.add(l);
      }
    }
    frame.pack();
    frame.setVisible(true);
  }
}

The end result would look something like this:

Hope this helps.

您应该小心添加顺序，容器是在 GridLayout 中一列又一列地填充的。

frame.setLayout( new GridLayout( level.rows, level.columns );

for (int c = 0; c < level.columns; r++) 
    for (int r = 0; r < level.rows; c++) 
         frame.add(fields[r][c]);

You should be careful about adding order, container is filled column after column in GridLayout.

frame.setLayout( new GridLayout( level.rows, level.columns );

for (int c = 0; c < level.columns; r++) 
    for (int r = 0; r < level.rows; c++) 
         frame.add(fields[r][c]);
