想了解C#实现主窗体最小化后出现悬浮框及双击悬浮框恢复原窗体的方法的相关内容吗,我心依旧在本文为您仔细讲解C#主窗体最小化后出现悬浮框及双击悬浮框恢复原窗体的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:C#,窗体,最小化,悬浮框,下面大家一起来学习吧。

本文实例讲述了C#实现主窗体最小化后出现悬浮框及双击悬浮框恢复原窗体的方法。分享给大家供大家参考。具体如下:

这里演示C#实现主窗体最小化后出现悬浮框,双击悬浮框恢复原窗体的效果。类似于360桌面。

主窗体:frmMain

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Threading;
namespace AppDemo
{
  public partial class frmMain : Form
  {
    public frmMain()
    {
      InitializeComponent();
    }
    /// <summary>
    /// 窗体初始状态
    /// </summary>
    private FormWindowState fwsPrevious;
    /// <summary>

    private frmTopMost myTopMost;

    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void frmMain_Load(object sender, EventArgs e)
    {
      fwsPrevious = this.WindowState;
      myTopMost = new frmTopMost(this);
    }
    /// <summary>

    private void frmMain_SizeChanged(object sender, EventArgs e)
    {
      if (this.WindowState == FormWindowState.Minimized)
      {
        myTopMost.Show();
        this.ShowInTaskbar = false;
      }
      else if (this.WindowState != fwsPrevious)
      {
        fwsPrevious = this.WindowState;
      }
    }
    /// <summary>
    /// 还原窗口方法,即供悬浮窗口进行调用的。
    /// </summary>
    public void RestoreWindow()
    {
      this.WindowState = fwsPrevious;
      this.ShowInTaskbar = true;
    }
  }
}

悬浮子窗体:frmTopMost

        Location = ptFormNewPos;
        ptFormPos = ptFormNewPos;
