How to move an image into a form windows form.
I used the following code:
private void button1_Click(object sender, EventArgs e)
{
int tamanhoFundo = picFundo.Width;
int x = myPic.Location.X;
int y = myPic.Location.Y;
while (x < tamanhoFundo)
{
int pos = x += 5;
myPic.Location = new Point(pos, myPic.Location.Y);
Thread.Sleep(500);
}
}
Even move the image, only a trace remains:
How to avoid this?
If the image is above picFundo , before calling Thred.Sleep give Refresh() in the background. Look at the code below:
private void button1_Click(object sender, EventArgs e)
{
int tamanhoFundo = picFundo.Width;
int x = myPic.Location.X;
int y = myPic.Location.Y;
while (x < tamanhoFundo)
{
int pos = x += 5;
myPic.Location = new Point(pos, myPic.Location.Y);
picFundo.Refresh();
Thread.Sleep(500);
}
}
This is a deliberate occurrence of System.Windows.Forms itself, which is concerned with increasing window rendering performance. But you can disable this with the method Refresh() and Update() , the two are great render your window. see the example based on your code:
private void button1_Click(object sender, EventArgs e)
{
int tamanhoFundo = picFundo.Width;
int x = myPic.Location.X;
int y = myPic.Location.Y;
while (x < tamanhoFundo)
{
int pos = x += 5;
myPic.Location = new Point(pos, myPic.Location.Y);
myPic.Refresh(); myPic.Update();
Thread.Sleep(250); // Também é bom reduzir o tempo de Sleep, pois os métodos Refresh() e Update() consomem um pouco de memória para re-criar o componente, então, de 500 vamos colocar 250.
}
}
