在使用 Winform 开发过程当中,常常发些由于显示器分辨率、窗体大小改变,控件却不能自适应变化,几经查找资料,和大佬的代码。通过细小修改,终于能够让窗体在外界影响下,窗体内背景图片、控件都会自适应变化大小(相似于网页的响应式)。缓存
完整代码以下:this
using System; using System.Drawing; using System.Windows.Forms; namespace AutoSizeForm { public partial class FrmMain : Form { private float X; private float Y; public FrmMain() { InitializeComponent(); } 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); } } } //窗体Resize事件 private void FrmMain_Resize(object sender, EventArgs e) { float newx = Width / X; float newy = Height / Y; SetControls(newx, newy, this); Text = Width.ToString() + " " + Height.ToString(); } //窗体Load事件 private void FrmMain_Load(object sender, EventArgs e) { Resize += new EventHandler(FrmMain_Resize); X = Width; Y = Height; SetTag(this); FrmMain_Resize(new object(), new EventArgs());//x,y可在实例化时赋值,最后这句是新加的,在MDI时有用 } } }
注意:在使用过程中发现画面卡顿,能够打开窗体属性双缓存(DoubleBuffered属性改成True)。spa
