鼠标滚轮移动不想让滚动条移动，怎么写代码
我操作鼠标滚轮 放大我画的矢量图形，但是不想让滚动条动
我直接把图画在Form1中，没有其他控件
private void Form1_Paint(object sender, PaintEventArgs e)
{
Graphics dc = e.Graphics;
dc.PageScale = more;
dc.TranslateTransform(this.AutoScrollPosition.X, this.AutoScrollPosition.Y);
for (int i = 0; i < 400; ++i)
{
for (int j = 0; j < 400; ++j)
{
switch (txt[i, j])
{
case '.':
draw(dc, Brushes.Gray, j, i); //灰色
break;
case '0':
draw(dc, Brushes.White, j, i); //白色
break;
case '1':
draw(dc, Brushes.LightBlue, j, i); //浅蓝色
break;
case '9':
draw(dc, Brushes.DarkBlue, j, i); //深蓝色
break;
default:
break;
}
}
}
}
float more = 1.0F;
private void Form1_MouseWheel(object sender, MouseEventArgs e)
{
if (e.Delta > 0)
{
++more;
}
if (e.Delta < 0)
{
if (!(more == 1))
{
--more; ;
}
}
this.Invalidate();
}
