Я написал этот код:
private struct MovePoint
{
public int X;
public int Y;
}
private void Image_MouseDown(object sender, MouseEventArgs e)
{
FirstPoint = new MovePoint();
FirstPoint.X = e.X;
FirstPoint.Y = e.Y;
}
private void Image_MouseMove(object sender, MouseEventArgs e)
{
if(e.Button == MouseButtons.Left)
{
if(FirstPoint.X > e.X)
{
Rectangle.X = FirstPoint.X - e.X;
//Rectangle.Width -= FirstPoint.X - e.X;
} else
{
Rectangle.X = FirstPoint.X + e.X;
//Rectangle.Width += FirstPoint.X + e.X;
}
if(FirstPoint.Y > e.Y)
{
Rectangle.Y = FirstPoint.Y - e.Y;
//Rectangle.Height -= FirstPoint.Y - e.Y;
} else
{
Rectangle.Y = FirstPoint.Y + e.Y;
//Rectangle.Height += FirstPoint.Y + e.Y;
}
Image.Invalidate();
}
}
private void Image_Paint(object sender, PaintEventArgs e)
{
if(Pen != null) e.Graphics.DrawRectangle(Pen, Rectangle);
}
Прямоугольник движется, но с инверсией (так быть не должно). Вы можете помочь?
