请问怎样在 鼠标移动的时候触发 OnPaint(PaintEventArgs e)?

[thankuu]

有以下两个void,一个鼠标移动的,一个是画图的,我现在想鼠标移动的时候触发 OnPaint(PaintEventArgs e), 请问怎样实现?

protected override void OnMouseMove(MouseEventArgs e)
{
...........
}

protected override void OnPaint(PaintEventArgs e)
{
................
}

[zag]

protected override void OnMouseMove(MouseEventArgs e)
{
...........
this.update();
}

如下
protected override void OnMouseMove(MouseEventArgs e)
{
Graphics f = this.CreateGraphics ();
System.Drawing .Rectangle cliprect = new Rectangle (0,0,ClientSize.Width ,ClientSize.Height);
this.OnPaint(new System.Windows.Forms.PaintEventArgs(f,cliprect));
}
