主要功能:
C#让窗体最小化至任务栏,同时在系统托盘区的图标点击左键能显示窗体,并使窗体闪烁。
首先:
创建窗体应用程序,并添加控件NotifyIcon及ContextMenuStrip控件
NotifyIcon:点击notifyIcon1属性,为控件属性Icon添加图标
contextMenuStrip1属性,进入Items添加或右键"编辑项".添加4个toolStripMenuItem,设置其Text为"显示窗体"、"隐藏窗体"、"开始闪烁"、"退出"
代码:
点击窗体"关闭"按钮时,取消关闭操作且窗体隐藏,任务栏图标仍然显示:
//窗体关闭前发生事件
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true; //取消关闭操作 表现为不关闭窗体
this.Hide(); //隐藏窗体
}
}
1.左键点击图标时,显示窗体.
2.当鼠标右键点击图标时,显示"显示窗体"\"隐藏窗体"\"闪烁"\"退出"菜单栏,并有相对应的功能
//"显示窗体"单击事件
private void 显示ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Show(); //窗体显示
this.WindowState = FormWindowState.Normal; //窗体状态默认大小
this.Activate();
}
//"隐藏窗体"单击事件
private void 隐藏ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Hide(); //隐藏窗体
}
//"退出"单击事件
private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)
{
//点击"是(YES)"退出程序
if (MessageBox.Show("确定要退出程序?", "安全提示",
System.Windows.Forms.MessageBoxButtons.YesNo,
System.Windows.Forms.MessageBoxIcon.Warning)
== System.Windows.Forms.DialogResult.Yes)
{
notifyIcon1.Visible = false; //设置图标不可见
this.Close(); //关闭窗体
this.Dispose(); //释放资源
Application.Exit(); //关闭应用程序窗体
}
}
鼠标左键图标显示窗体功能
//鼠标左键图标事件
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
//点击鼠标"左键"发生
if (e.Button == MouseButtons.Left)
{
this.Visible = true; //窗体可见
this.WindowState = FormWindowState.Normal; //窗体默认大小
this.notifyIcon1.Visible = true; //设置图标可见
}
}
图标闪烁
闪烁的效果是加上一个空白的图标,正常图标与空白图标的切换进而实现闪烁的效果。
property是vs的一个资源管理功能,可以存储系统图标及一些常量
private Icon timg = Properties.Resources.timg;
private Icon blank = Properties.Resources.blank;//透明的图标
private bool _status = true;
private bool _isBlink = false;
右键菜单控制图标是不是显示
private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
if (_isBlink == false)
{
_isBlink = true;
timer1.Enabled = true;
timer1.Start();
}
else
{
_isBlink = false;
timer1.Stop();
//气泡提示
notifyIcon1.ShowBalloonTip(, "提示", "关闭闪烁效果!", ToolTipIcon.Info);
}
}
定时器中修改图标的状态,定时反转图标
private void timer1_Tick(object sender, EventArgs e)
{ if (_status)
notifyIcon1.Icon = timg;
else
notifyIcon1.Icon = blank; _status = !_status;
}
完整代码:
public partial class Form1 : Form
{
private Icon timg = Properties.Resources.timg;
private Icon blank = Properties.Resources.blank;//透明的图标
private bool _status = true;
private bool _isBlink = false;
public Form1()
{
InitializeComponent();
} //窗体关闭前发生事件
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true; //取消关闭操作 表现为不关闭窗体
this.Hide(); //隐藏窗体
}
}
//"显示窗体"单击事件
private void 显示ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Show(); //窗体显示
this.WindowState = FormWindowState.Normal; //窗体状态默认大小
this.Activate();
}
//"隐藏窗体"单击事件
private void 隐藏ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Hide(); //隐藏窗体
}
//"退出"单击事件
private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)
{
//点击"是(YES)"退出程序
if (MessageBox.Show("确定要退出程序?", "安全提示",
System.Windows.Forms.MessageBoxButtons.YesNo,
System.Windows.Forms.MessageBoxIcon.Warning)
== System.Windows.Forms.DialogResult.Yes)
{
notifyIcon1.Visible = false; //设置图标不可见
this.Close(); //关闭窗体
this.Dispose(); //释放资源
Application.Exit(); //关闭应用程序窗体
}
}
//鼠标左键图标事件
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
//点击鼠标"左键"发生
if (e.Button == MouseButtons.Left)
{
this.Visible = true; //窗体可见
this.WindowState = FormWindowState.Normal; //窗体默认大小
this.notifyIcon1.Visible = true; //设置图标可见
}
} private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
if (_isBlink == false)
{
_isBlink = true;
timer1.Enabled = true;
timer1.Start();
}
else
{
_isBlink = false;
timer1.Stop();
//气泡提示
notifyIcon1.ShowBalloonTip(, "提示", "关闭闪烁效果!", ToolTipIcon.Info);
}
}
private void timer1_Tick(object sender, EventArgs e)
{ if (_status)
notifyIcon1.Icon = timg;
else
notifyIcon1.Icon = blank; _status = !_status;
} }
