在winform中利用GDI画三角形并且移动位置的问题
题目要求是这样的,在C#的winform窗口绘制一个三角形(等边),这个三角形最初位置是左上角。然后缓慢向右下角移动,在移动过程成三角形自身也在旋转。并且每次窗口改变大小时,这个三角形都会重新回到左上角,再重复移动和旋转的动作请各位前辈给个思路啊,我不知道该怎么写 --------------------编程问答-------------------- 学习... --------------------编程问答-------------------- 求教求教求教!!!!!!! --------------------编程问答-------------------- 1.DrawRect
2.timer
3.formsizechange
4.TranslateTransform --------------------编程问答-------------------- 一个简单写的,效果自己调整
--------------------编程问答-------------------- 可以试试 --------------------编程问答--------------------

private Point[] ps = new Point[3];
private float rotate=0;
public Form2()
{
InitializeComponent();
SetRect(0,0);
}
private void Form2_Paint(object sender, PaintEventArgs e)
{
DrawTriangle(e.Graphics);
//e.Graphics.DrawRectangle(Pens.Blue, this.rect);
}
private void DrawTriangle(Graphics g)
{
g.TranslateTransform(rect.X, 0);
g.RotateTransform(rotate);
g.FillPolygon(new SolidBrush(Color.Red), ps);
}
private void SetRect(int x,int y)
{
rect.X = rect.X + x;
rect.Y = rect.Y + y;
rect.Width = 100;
rect.Height = 100;
ps[0].X = rect.X;
ps[0].Y = rect.Bottom;
ps[1].X = rect.X + rect.Width / 2;
ps[1].Y = rect.Top;
ps[2].X = rect.Right;
ps[2].Y = rect.Bottom;
}
private void timer1_Tick(object sender, EventArgs e)
{
rotate += 5f;
SetRect(10, 10);
this.Invalidate();
}
}
}
谢谢,我试试哈 --------------------编程问答-------------------- 顶一个。 学习中 --------------------编程问答-------------------- MARK
