C#--winform窗体控件随窗体变化


分类专栏：

c#

今天说一下在winform窗体应用中，如何使窗体内控件大小随着窗体变化。因为在默认的情况下，点击最大化的按钮，我们发现窗体内的控件大小不变，这就有些尴尬了！

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.IO;

using System.Runtime.InteropServices;

using System.Threading;

namespace Sequence_C_sharp

{

public partial class Form1 : Form

{

//------------------------------------------------------ 控件大小随窗体大小变化

private float X;

private float Y;

private void setTag(Control cons)

{

foreach (Control con in cons.Controls)

{

con.Tag = con.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;

if (con.Controls.Count > 0) setTag(con);

}

}

private void setControls(float newx, float newy, Control cons)

{

foreach (Control con in cons.Controls)

{

string[] mytag = con.Tag.ToString().

Split(new char[] { ':' });

float a = Convert.ToSingle(mytag[0]) * newx;

con.Width = (int)a;

a = Convert.ToSingle(mytag[1]) * newy; con.Height = (int)(a);

a = Convert.ToSingle(mytag[2]) * newx; con.Left = (int)(a);

a = Convert.ToSingle(mytag[3]) * newy; con.Top = (int)(a);

Single currentSize = Convert.ToSingle(mytag[4]) * Math.Min(newx, newy);

con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);

if (con.Controls.Count > 0)

{ setControls(newx, newy, con); }

}

}

void Form1_Resize(object sender, EventArgs e)

{

float newx = (this.Width) /

X; float newy = this.Height /

Y; setControls(newx, newy, this);

this.Text = this.Width.ToString() + " " + this.Height.ToString(); }

//-------------------------------------------------------------------------- 控件大小随窗体大小变化结束

private void Form1_Load(object sender, EventArgs e)

{

//--------------------------------控件大小随窗体大小变化

this.Resize += new EventHandler(Form1_Resize);

X = this.Width;

Y = this.Height;

setTag(this);

Form1_Resize(new object(), new EventArgs());

//---------------------------------控件大小随窗体大小变化

}

}
