微软提供了这样的API函数可以实现The DrawAnimatedRects function draws a wire-frame rectangle and animates it to indicate the opening of an icon or the minimizing or maximizing of a window.BOOL DrawAnimatedRects( HWND hwnd, // handle to clipping window int idAni, // type of animation CONST RECT *lprcFrom, // rectangle coordinates (minimized) CONST RECT *lprcTo // rectangle coordinates (restored) );
VB.NET Public Class Form1 '恢复最小化到托盘的程序 Private Sub 显示窗体ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles 显示窗体ToolStripMenuItem.Click Me.WindowState = FormWindowState.Normal End Sub Private Sub 退出ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles 退出ToolStripMenuItem.Click End End SubEnd Class
{
if (this.WindowState == FormWindowState.Minimized)
this.WindowState = FormWindowState.Normal;
this.Activate();
}
写代码:
private void Form1_SizeChanged(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Visible = false;
notifyIcon1.Visible = true;
}
} private void notifyIcon1_Click(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Visible = true;
this.WindowState =FormWindowState.Normal;
notifyIcon1.Visible = false;
}
}
即可
{
if (this.WindowState == FormWindowState.Minimized)
{
this.WindowState = FormWindowState.Normal;
this.Activate();
}
else
{
this.WindowState = FormWindowState.Minimized;
}
}notifyIcon的属性的Icon要设置一个ico的图标文件,不然可能在托盘里面看不见!
private void Form1_SizeChanged(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Visible = false;
notifyIcon1.Visible = true;
}
}
private void Form1_Resize(object sender, System.EventArgs e) {
if (this.WindowState == FormWindowState.Minimized) {
this.Visible = false;
this.notifyIcon1.Visible = true;
}
}private void notifyIcon1_Click(object sender, System.EventArgs e) {
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.notifyIcon1.Visible = false;
}
这个特效要自己写的...你可以在QQ窗体当按下"最小化"...就显示出一个大小只和QQ窗体的标题大小的一个小窗体...再用一个Timer来控制动画帧...窗体递减大小...还有X,Y坐标递加...就行了...托盘的位置是可以算出来的...这个算法你自己想吧...很简单...
private System.Windows.Forms.NotifyIcon notifyIconServer;
this.notifyIconServer = new System.Windows.Forms.NotifyIcon(this.components); 接下来设置控件的各项属性:
//
// notifyIconServer
//
this.notifyIconServer.ContextMenu = this.contextMenuTray;//指定上下文菜单
this.notifyIconServer.Icon = ((System.Drawing.Icon)(resources.GetObject("notifyIconServer.Icon")));//指定图标
this.notifyIconServer.Text = "My Server";//指定鼠标悬停显示
this.notifyIconServer.MouseDown += new System.Windows.Forms.MouseEventHandler(this.notifyIconServer_MouseDown);
this.notifyIconServer.DoubleClick += new System.EventHandler(this.notifyIconServer_DoubleClick); //
// contextMenuTray 上下文菜单
//
this.contextMenuTray.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {
this.menuItem1,
this.menuItem2});
//
// menuItem1
//
this.menuItem1.Index = 0;
this.menuItem1.Text = "打开 Chat Server";
this.menuItem1.Click += new System.EventHandler(this.menuItem1_Click);
//
// menuItem2
//
this.menuItem2.Index = 1;
this.menuItem2.Text = "退出程序";
this.menuItem2.Click += new System.EventHandler(this.menuItem2_Click); 用户点击窗体的“关闭”小按钮时,并不真正关闭窗体,而是将程序放到系统托盘。 private void ChatForm_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true; // 取消关闭窗体
this.Hide();
this.ShowInTaskbar = false;
this.notifyIconServer.Visible = true;//显示托盘图标
} notifyIcon的双击事件,可以恢复程序窗体: private void notifyIconServer_DoubleClick(object sender, System.EventArgs e)
{
this.Show();
if (this.WindowState == FormWindowState.Minimized)
this.WindowState = FormWindowState.Normal;
this.Activate();
} 附加要求:单击鼠标左键也可调出一菜单。 解决方案如下: 首先声明一个上下文菜单: //
// contextMenuLeft 左键菜单
//
this.contextMenuLeft.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {
this.menuItem3});
//
// menuItem3
//
this.menuItem3.Index = 0;
this.menuItem3.Text = "关于……"; 由于不能在notifyIcon上直接显示上下文菜单,只有创建一个Control作为容器,这是权宜之计,应该有更好的方法吧。
private void notifyIconServer_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
if(e.Button==MouseButtons.Left)
{
Control control = new Control(null,Control.MousePosition.X,Control.MousePosition.Y,1,1);
control.Visible = true;
control.CreateControl();
Point pos = new Point(0,0);//这里的两个数字要根据你的上下文菜单大小适当地调整
this.contextMenuLeft.Show(control,pos);
}
}
