C# 方形拆分

Question

我这样做纯粹是出于好奇，几天来我一直在尝试这样做，但我似乎被卡住了。

我正在尝试执行以下操作：

目前，我只想让其中一个方块在我每次单击它时无限分割。这是我正在处理的代码：

using System;
using System.Drawing;
using System.Windows.Forms;

namespace divideSquare
{
    public partial class Form1 : Form
    {
        private Button centerSquare = new Button();
        private Button topLeftSquare = new Button();
        private Button topRightSquare = new Button();
        private Button bottomLeftSquare = new Button();
        private Button bottomRightSquare = new Button();

        public Form1()
        {
            InitializeComponent();
        }

        private void square_Click( object sender, EventArgs e )
        {
            topLeftSquare.Click += new EventHandler( topLeftSquare_Click );
            //topRightSquare.Click += new EventHandler( topRightSquare_Click );
            //bottomLeftSquare.Click += new EventHandler( bottomLeftSquare_Click );
            //bottomRightSquare.Click += new EventHandler( bottomRightSquare_Click );

            topLeftSquare.Size = new System.Drawing.Size( centerSquare.Height / 2, centerSquare.Width / 2 );
            topRightSquare.Size = new System.Drawing.Size( centerSquare.Height / 2, centerSquare.Width / 2 );
            bottomLeftSquare.Size = new System.Drawing.Size( centerSquare.Height / 2, centerSquare.Width / 2 );
            bottomRightSquare.Size = new System.Drawing.Size( centerSquare.Height / 2, centerSquare.Width / 2 );

            topLeftSquare.Location = new Point( 0, 0 );
            topRightSquare.Location = new Point( 50, 0 );
            bottomLeftSquare.Location = new Point( 0, 50 );
            bottomRightSquare.Location = new Point( 50, 50 );

            topLeftSquare.BackColor = Color.Red;
            topRightSquare.BackColor = Color.Red;
            bottomLeftSquare.BackColor = Color.Red;
            bottomRightSquare.BackColor = Color.Red;

            this.Controls.Add( topLeftSquare );
            this.Controls.Add( topRightSquare );
            this.Controls.Add( bottomLeftSquare );
            this.Controls.Add( bottomRightSquare );

            centerSquare.Dispose();
        }

        private void topLeftSquare_Click( object sender, EventArgs e )
        {
            topLeftSquare.Click += new EventHandler( topLeftSquare_Click );
            //topRightSquare.Click += new EventHandler( topRightSquare_Click );
            //bottomLeftSquare.Click += new EventHandler( bottomLeftSquare_Click );
            //bottomRightSquare.Click += new EventHandler( bottomRightSquare_Click );

            topLeftSquare.Size = new System.Drawing.Size( topLeftSquare.Height / 2, topLeftSquare.Width / 2 );
            topRightSquare.Size = new System.Drawing.Size( topLeftSquare.Height / 2, topLeftSquare.Width / 2 );
            bottomLeftSquare.Size = new System.Drawing.Size( topLeftSquare.Height / 2, topLeftSquare.Width / 2 );
            bottomRightSquare.Size = new System.Drawing.Size( topLeftSquare.Height / 2, topLeftSquare.Width / 2 );

            topLeftSquare.Location = new Point( 0, 0 );
            topRightSquare.Location = new Point( 10, 0 );
            bottomLeftSquare.Location = new Point( 0, 10 );
            bottomRightSquare.Location = new Point( 10, 10 );

            topLeftSquare.BackColor = Color.Red;
            topRightSquare.BackColor = Color.Red;
            bottomLeftSquare.BackColor = Color.Red;
            bottomRightSquare.BackColor = Color.Red;

            this.Controls.Add( topLeftSquare );
            this.Controls.Add( topRightSquare );
            this.Controls.Add( bottomLeftSquare );
            this.Controls.Add( bottomRightSquare );

        }

        private void Form1_Load( object sender, EventArgs e )
        {
            centerSquare.Click += new EventHandler( square_Click );
            centerSquare.Size = new System.Drawing.Size( 50, 50 );
            centerSquare.BackColor = Color.Red;
            this.Controls.Add( centerSquare );
        }
    }
}

但是每次我点击一个正方形它都不会分裂，而是所有的按钮都变得越来越小（这是预期的行为但它只适用于一个正方形并且预计会被切成 4也是）。

如有任何帮助，我们将不胜感激。

您需要一个方形层次结构。请参阅下面的更改。我没有调试代码，只是给出了问题的基本解决方案。

Answer 2

我刚刚尝试了您的代码并进行了一些修改。请使用下面的代码，它按照您需要的方式工作。代码是不言自明的。如果您需要任何代码行的帮助，请告诉我。希望对你有帮助

public partial class Form1 : Form
    {
        private Button centerSquare = new Button();
        private Button topLeftSquare = new Button();
        private Button topRightSquare = new Button();
        private Button bottomLeftSquare = new Button();
        private Button bottomRightSquare = new Button();
        public Form1()
        {
            InitializeComponent();
        }

        private void square_Click(object sender, EventArgs e)
        {
            Split(sender as Button);
            centerSquare.Dispose();
        }

        private void topLeftSquare_Click(object sender, EventArgs e)
        {
            Split(sender as Button);
        }

        private void Split(Button source)
        {
            Button topRightSquare = new Button();
            Button bottomLeftSquare = new Button();
            Button bottomRightSquare = new Button();

            topLeftSquare.Click += new EventHandler(topLeftSquare_Click);

            int width = source.Height / 2;

            topLeftSquare.Size = new System.Drawing.Size(width,width);
            topRightSquare.Size = new System.Drawing.Size(width, width);
            bottomLeftSquare.Size = new System.Drawing.Size(width, width);
            bottomRightSquare.Size = new System.Drawing.Size(width, width);

            topLeftSquare.Location = new Point(0, 0);
            topRightSquare.Location = new Point(topLeftSquare.Width, 0);
            bottomLeftSquare.Location = new Point(0, topLeftSquare.Height);
            bottomRightSquare.Location = new Point(topLeftSquare.Width , topLeftSquare.Height );

            topLeftSquare.BackColor = Color.Red;
            topRightSquare.BackColor = Color.Red;
            bottomLeftSquare.BackColor = Color.Red;
            bottomRightSquare.BackColor = Color.Red;

            this.Controls.Add(topLeftSquare);
            this.Controls.Add(topRightSquare);
            this.Controls.Add(bottomLeftSquare);
            this.Controls.Add(bottomRightSquare);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            centerSquare.Click += new EventHandler(square_Click);
            centerSquare.Size = new System.Drawing.Size(400, 400);
            centerSquare.BackColor = Color.Red;
            this.Controls.Add(centerSquare);
        }

    }

Answer 3

这是我对此的看法...

首先，我将按钮声明删除到 square_Click 方法中，因为每次您需要创建新按钮时，您的代码只是重复使用在创建表单时实例化的按钮。这是现有代码的最大问题。

其次，由于单击每个按钮执行相同的代码，我将两种方法（square_Click 和 topLeftSquare_Click）合并为一种方法。

看看：

public partial class Form1 : Form
{
    private Button centerSquare = new Button();

    public Form1()
    {
        InitializeComponent();
    }

    private void square_Click(object sender, EventArgs e)
    {
        Button topLeftSquare = new Button();
        Button topRightSquare = new Button();
        Button bottomLeftSquare = new Button();
        Button bottomRightSquare = new Button();

        Button senderSquare = sender as Button;
        topLeftSquare.Click += new EventHandler(square_Click);
        topRightSquare.Click += new EventHandler(square_Click);
        bottomLeftSquare.Click += new EventHandler(square_Click);
        bottomRightSquare.Click += new EventHandler(square_Click);

        int newSquareHeight = senderSquare.Height / 2;
        int newSquareWidth = senderSquare.Width / 2;

        topLeftSquare.Size = new System.Drawing.Size(newSquareHeight, newSquareWidth);
        topRightSquare.Size = new System.Drawing.Size(newSquareHeight, newSquareWidth);
        bottomLeftSquare.Size = new System.Drawing.Size(newSquareHeight, newSquareWidth);
        bottomRightSquare.Size = new System.Drawing.Size(newSquareHeight, newSquareWidth);

        topLeftSquare.Location = new Point(senderSquare.Left, senderSquare.Top);
        topRightSquare.Location = new Point(senderSquare.Left + newSquareHeight, senderSquare.Top);
        bottomLeftSquare.Location = new Point(senderSquare.Left, senderSquare.Top + newSquareWidth);
        bottomRightSquare.Location = new Point(senderSquare.Left + newSquareHeight, senderSquare.Top + newSquareWidth);

        topLeftSquare.BackColor = Color.Red;
        topRightSquare.BackColor = Color.Red;
        bottomLeftSquare.BackColor = Color.Red;
        bottomRightSquare.BackColor = Color.Red;

        this.Controls.Add(topLeftSquare);
        this.Controls.Add(topRightSquare);
        this.Controls.Add(bottomLeftSquare);
        this.Controls.Add(bottomRightSquare);

        this.Controls.Remove(senderSquare);
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        centerSquare.Click += new EventHandler(square_Click);
        centerSquare.Size = new System.Drawing.Size(50, 50);
        centerSquare.BackColor = Color.Red;
        this.Controls.Add(centerSquare);
    }
}
