我正在制作一个C#WinForms应用程序.由于某种原因,表单的MouseMove和MouseClick事件不会被触发. (当我发现原因时,我可能会觉得自己像个白痴.)
它是一个透明的表单(TransparencyKey设置为背景颜色),在图片框中有一个半透明的动画gif.我正在制作一个屏幕保护程序.
有什么建议?
编辑:
MainScreensaver.cs
Random randGen = new Random();
public MainScreensaver(Rectangle bounds)
{
InitializeComponent();
this.Bounds = Bounds;
}
private void timer1_Tick(object sender, EventArgs e)
{
Rectangle screen = Screen.PrimaryScreen.Bounds;
Point position = new Point(randGen.Next(0,screen.Width-this.Width)+screen.Left,randGen.Next(0,screen.Height-this.Height)+screen.Top);
this.Location = position;
}
private void MainScreensaver_Load(object sender, EventArgs e)
{
Cursor.Hide();
TopMost = true;
}
private Point mouseLocation;
private void MainScreensaver_MouseMove(object sender, MouseEventArgs e)
{
if (!mouseLocation.IsEmpty)
{
// Terminate if mouse is moved a significant distance
if (Math.Abs(mouseLocation.X - e.X) > 5 ||
Math.Abs(mouseLocation.Y - e.Y) > 5)
Application.Exit();
}
// Update current mouse location
mouseLocation = e.Location;
}
private void MainScreensaver_KeyPress(object sender, KeyPressEventArgs e)
{
Application.Exit();
}
private void MainScreensaver_Deactive(object sender, EventArgs e)
{
Application.Exit();
}
private void MainScreensaver_MouseClick(object sender, MouseEventArgs e)
{
Application.Exit();
}
摘自MainScreensaver.Designer.cs InitialiseComponent()
this.MouseClick += new System.Windows.Forms.MouseEventHandler(this.MainScreensaver_MouseClick);
this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.MainScreensaver_MouseMove);
解决方法:
你确定你的表格有焦点吗?如果表单没有焦点,则不会触发鼠标事件.
