WINFORM 自己写的全屏事件 有办法避免全屏的过程中窗体闪烁吗？
首先相关代码：
private void control_magnify(double fw, double fh)//按长宽比例变动调整控件位置 放大用
{
int x;
int y;

//x = Convert.ToInt32(panel2.Location.X * fw);
//y = Convert.ToInt32(panel2.Location.Y * fh);
//panel2.Location = new Point(x, y);
x = Convert.ToInt32(panel2.Size.Width * fw);
y = Convert.ToInt32(panel2.Size.Height * fh);
panel2.Size = new Size(x, y);
//x = Convert.ToInt32(panel3.Location.X * fw);
//y = Convert.ToInt32(panel3.Location.Y * fh);
//panel3.Location = new Point(x, y);

y = Convert.ToInt32(panel3.Size.Height * fh);

}
}
