如图,拖动窗体即可改变控件大小(包括字体)
窗体尺寸:345*315
窗体尺寸:603*509
项目资源如下
源码实现如下
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace 控件随窗体自动调整 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } //在Form_Load中添加代码 private void Form1_Load(object sender, EventArgs e) { this.Resize += new EventHandler(Form1_Resize); X = this.Width; Y = this.Height; setTag(this); Form1_Resize(new object(), new EventArgs()); } //***控制控件大小及文字大小开始***// 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 = "窗体尺寸:"+this.Width.ToString() + " " + this.Height.ToString(); } //***控制控件大小及文字大小结束***// } }
如果想实现控件随窗体大小变化,不包含字体,怎么做?
方法很简单,以Button控件为例,仅需要设置其Anchor属性为“Top,Bottom,Left,Right”即可。
