摘要
简单实现了一个这样的功能,程序启动时,窗口悬固定在右下角,并可以通过鼠标拖拽移动。
核心代码块
无边框窗口并不出现在任务栏
//无边框
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
//不出现在任务栏
this.ShowInTaskbar = false;
置顶
this.TopMost = true;
拖拽移动无边框窗口
//全局窗口坐标
private Point _frmPoint;
public MainFrm()
{
InitializeComponent();
this.TopMost = true;
_frmPoint = new Point();
}
private void MainFrm_Load(object sender, EventArgs e)
{
this.MouseDown += MainFrm_MouseDown;
this.MouseMove += MainFrm_MouseMove;
}
void MainFrm_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
Point myPosittion = MousePosition;
myPosittion.Offset(-_frmPoint.X, -_frmPoint.Y);
Location = myPosittion;
}
} void MainFrm_MouseDown(object sender, MouseEventArgs e)
{
_frmPoint.X = e.X;
_frmPoint.Y = e.Y;
}
可实现类似杀毒软件悬浮的窗口。
