WinForm中實現最小化到系統托盤
if(this.WindowState == FormWindowState.Minimized) //判斷是否最小化{
this.ShowInTaskbar =false; //不顯示在系統工作列 notifyIcon.Visible =true; //托盤圖示可見}
４、實現NotifyIcon控制元件的DoubleClick事件，程式碼如下：
if(this.WindowState == FormWindowState.Minimized)
{
this.ShowInTaskbar =true; //顯示在系統工作列
例題：
private ContextMenu notifyiconMnu;
#region 最小化到工作列
/// <summary>
/// 最小化到工作列
/// </summary>
private void Initializenotifyicon()
{
//定義一個MenuItem陣列，並把此陣列同時賦值給ContextMenu物件
MenuItem[] mnuItms = new MenuItem[3];
mnuItms[0] = new MenuItem();
mnuItms[0].Text = "顯示視窗";
mnuItms[0].Click += new System.EventHandler(this.notifyIcon1_showfrom);
mnuItms[1] = new MenuItem("-");
mnuItms[2] = new MenuItem();
mnuItms[2].Text = "退出系統";
mnuItms[2].Click += new System.EventHandler(this.ExitSelect);
mnuItms[2].DefaultItem = true;
notifyiconMnu = new ContextMenu(mnuItms);
notifyIcon1.ContextMenu = notifyiconMnu;
//為托盤程式加入設定好的ContextMenu物件
}
private void notifyIcon1_DoubleClick(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Show();
this.ShowInTaskbar = true;
this.WindowState = FormWindowState.Normal;
notifyIcon1.Visible = false;
}
}
public void notifyIcon1_showfrom(object sender, System.EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Show();
this.ShowInTaskbar = true;
this.WindowState = FormWindowState.Normal;
notifyIcon1.Visible = false;
}
}
public void ExitSelect(object sender, System.EventArgs e)
{
//隱藏托盤程式中的圖示
notifyIcon1.Visible = false;
//關閉系統
this.Close();
this.Dispose(true);
}
#endregion
private void Form_main_SizeChanged(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized) //判斷是否最小化
{
notifyIcon1.Visible = true;
this.Hide();
this.ShowInTaskbar = false;
Initializenotifyicon();
}
}
