以前试过在WinForm中自定义鼠标样式,结果显示出来的鼠标变成单色。 后来百度了下,原来要用API来做。 首先引入两个命名空间
using System.Runtime.InteropServices;
using System.Reflection; 导入API
[DllImport("user32.dll")]
public static extern IntPtr LoadCursorFromFile(string fileName); [DllImport("user32.dll")] public static extern IntPtr SetCursor(IntPtr cursorHandle); [DllImport("user32.dll")] public static extern uint DestroyCursor(IntPtr cursorHandle); 接下来使用自己的鼠标样式
private void Form1_Load(object sender, EventArgs e)
{ Cursor myCursor = new Cursor(Cursor.Current.Handle); IntPtr colorCursorHandle = LoadCursorFromFile("my.cur");//鼠标图标路径 myCursor.GetType().InvokeMember("handle", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.SetField, null, myCursor, new object[] { colorCursorHandle }); this.Cursor = myCursor; } 现在介绍另一种不用API方式的,鼠标样式只需要一张背景透明的图片就行了,png或gif格式的 写个方法
public void SetCursor(Bitmap cursor, Point hotPoint)
{ int hotX = hotPoint.X; int hotY = hotPoint.Y; Bitmap myNewCursor = new Bitmap(cursor.Width * 2 - hotX, cursor.Height * 2 - hotY); Graphics g = Graphics.FromImage(myNewCursor); g.Clear(Color.FromArgb(0, 0, 0, 0)); g.DrawImage(cursor, cursor.Width - hotX, cursor.Height - hotY, cursor.Width, cursor.Height); this.Cursor = new Cursor(myNewCursor.GetHicon()); g.Dispose(); myNewCursor.Dispose(); } 在你想要改变鼠标样式的事件里头使用这个方法就行了
private void Form1_Load(object sender, EventArgs e)
{ Bitmap a=(Bitmap)Bitmap.FromFile("myCur.png"); SetCursor(a, new Point(0, 0)); } //this.btnBack.FlatStyle = FlatStyle.Flat; //set the button no frame
//this.btnBack.FlatAppearance.BorderSize = 0; 【Reprinted From http://www.cnblogs.com/hzbzxm/archive/2008/09/15.html】
