[英]How do I hide a window form when x is clicked and CLose through system tray ToolStripMenuItem
我是C#.Net的新手,我正在尋找一種方法,當單擊窗口中的“ X”(右上角的“關閉”按鈕)時隱藏表單窗口,並在我從系統任務欄上下文中單擊退出時關閉應用程序菜單
為了簡化我想做的事情,我想要像Skype這樣的東西,當單擊窗口的十字時,它可以通過系統托盤選項退出並隱藏到系統嘗試下面是我的代碼,我嘗試在窗體關閉事件中將cancel屬性覆蓋為true但是它也停止了系統try選項的關閉過程,如何區分它們。
`using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private Icon ico;
private void Form1_Load(object sender, EventArgs e)
{
ico = notifyIcon1.Icon;
}
private void contextMenuStrip1_Opening(object sender, CancelEventArgs e)
{
}
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.Show();
}
private void button1_Click(object sender, EventArgs e)
{
this.Hide();
}
private void showFormToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Show();
}
private void quitFormToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Close();
}
private void Form1_FormClosing_1(object sender, FormClosingEventArgs e)
{
e.Cancel = true;
System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "CloseReason", e.CloseReason);
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel);
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "FormClosing Event");
}
}
}
`
通常,當我必須這樣做時,我會保留一個statusflag來記住該呼叫是從其他地方來關閉我的。 因此,在我的關閉處理程序中,我可以檢查是否需要關閉或隱藏...
bool bFormCloseRequested = false: //member of my Form
void MyCloseClick_Handler{object sender, eventArgs e)
{
if(!bFormCloseRequested)
{
e.Cancel = true;
this.hide();
}
}
