Timer计时器组件 Panel容器控件
实现代码：
private void timer1_Tick(object sender, EventArgs e)
{
left = 10;
this.panel1.Left += left;
if (this.panel1.Left > this.Width)
{
timer1.Enabled = false;
this.pictureBox1.Image=imageList1.Images[0];
this.pictureBox2.Image = imageList2.Images[0];
this.pictureBox3.Image = imageList3.Images[0];
timer2.Enabled = true;
}
}
private void Form1_Load(object sender, EventArgs e)
{
this.pictureBox1.Image = imageList1.Images[0];
this.pictureBox2.Image = imageList2.Images[0];
this.pictureBox3.Image = imageList3.Images[0];
}
private void timer2_Tick(object sender, EventArgs e)
{
left = -10;
this.panel1.Left += left;
if(this.panel1.Left<0)
{
timer2.Enabled = false;
this.pictureBox1.Image = imageList1.Images[1];
this.pictureBox2.Image = imageList2.Images[1];
this.pictureBox3.Image = imageList3.Images[1];
timer1.Enabled = true;
}
}
