之后就是窗体的鼠标函数了,里面很多代码都没有作出整理,看了一下,整理后的代码应该会更少更精简的
private void ScreenBody_DoubleClick(object sender, EventArgs e) { if (((MouseEventArgs)e).Button == MouseButtons.Left &&Rect.Contains(((MouseEventArgs)e).X, ((MouseEventArgs)e).Y)) { //保存的时候有很多种方法的......我这里只用了这种 Image memory = new Bitmap(Rect.Width, Rect.Height); Graphics g = Graphics.FromImage(memory); g.CopyFromScreen(Rect.X + 1, Rect.Y + 1, 0, 0, Rect.Size); Clipboard.SetImage(memory); this.Close(); } } private void ScreenBody_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { isDowned = true; if (RectReady == false) { Rect.X = e.X; Rect.Y = e.Y; downPoint = new Point(e.X, e.Y); } if (RectReady == true) { tmpx = e.X; tmpy = e.Y; } } if (e.Button == MouseButtons.Right) { if (RectReady != true) { this.Close(); return; } MainPainter.DrawImage(baseImage, 0, 0); RectReady = false; } } private void ScreenBody_MouseUp(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { isDowned = false; RectReady = true; } } private void ScreenBody_MouseMove(object sender, MouseEventArgs e) { if (RectReady == false) { if (isDowned == true) { Image New = DrawScreen((Image)baseImage.Clone(), e.X, e.Y); MainPainter.DrawImage(New, 0, 0); New.Dispose(); } } if (RectReady == true) { if (Rect.Contains(e.X, e.Y)) { //this.Cursor = Cursors.Hand; if (isDowned == true) { //和上一次的位置比较获取偏移量 Rect.X = Rect.X + e.X - tmpx; Rect.Y = Rect.Y + e.Y - tmpy; //记录现在的位置 tmpx = e.X; tmpy = e.Y; MoveRect((Image)baseImage.Clone(), Rect); } } } } private void ScreenBody_Load(object sender, EventArgs e) { this.WindowState = FormWindowState.Maximized; MainPainter = this.CreateGraphics(); pen = new Pen(Brushes.Blue); isDowned = false; baseImage = this.BackgroundImage; Rect = new Rectangle(); RectReady = false; } |
