Panel1_Paint如下:
private void panel1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Pen pen1 = new Pen(Color.Red);
Pen pen2 = new Pen(Color.Green);
SolidBrush brush1 = new SolidBrush(Color.Red);
SolidBrush brush2 = new SolidBrush(Color.Green);
for (int i = 0; i < 3; i++)
{
if (time >= 0 && time <= 3)
{
g.DrawEllipse(pen2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
g.FillEllipse(brush2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
}
else
{
g.DrawEllipse(pen2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
g.FillEllipse(brush2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
}
} Graphics g1 = e.Graphics;
Pen pen3 = new Pen(Color.White);
SolidBrush brush3 = new SolidBrush(Color.White);
for (int i = 0; i < 35; i++)
{
g1.DrawRectangle(pen3, 2 + i * 20, this.panel1.Height / 2-120, 10, 150);
g1.FillRectangle(brush3, 2 + i * 20, this.panel1.Height / 2-120, 10, 150);
}
}
timer1_Tick是这样写的
private void timer1_Tick(object sender, EventArgs e)
{
this.panel1_Paint(sender, e);
}但是这样有问题的
private void panel1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Pen pen1 = new Pen(Color.Red);
Pen pen2 = new Pen(Color.Green);
SolidBrush brush1 = new SolidBrush(Color.Red);
SolidBrush brush2 = new SolidBrush(Color.Green);
for (int i = 0; i < 3; i++)
{
if (time >= 0 && time <= 3)
{
g.DrawEllipse(pen2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
g.FillEllipse(brush2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
}
else
{
g.DrawEllipse(pen2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
g.FillEllipse(brush2, this.panel1.Width / 2 + i * 25, this.panel1.Height / 2 - 150, 20, 20);
}
} Graphics g1 = e.Graphics;
Pen pen3 = new Pen(Color.White);
SolidBrush brush3 = new SolidBrush(Color.White);
for (int i = 0; i < 35; i++)
{
g1.DrawRectangle(pen3, 2 + i * 20, this.panel1.Height / 2-120, 10, 150);
g1.FillRectangle(brush3, 2 + i * 20, this.panel1.Height / 2-120, 10, 150);
}
}
timer1_Tick是这样写的
private void timer1_Tick(object sender, EventArgs e)
{
this.panel1_Paint(sender, e);
}但是这样有问题的
{
this.panel1.Refresh();
}
