This might seem like a simple question...
I'm looking for the Label.Opacity property in C# Winforms.
What I wish to do is have a method that fade's out a label gradually. By means of a timer perhaps?
Since there is not Opacity I'm trying to set it's transperency to higher numbers untill it's high enough that the item should be invisible. But I can't seem to make this work.
Currently I have:
public FadeLabel()
{
MyTimer timer = new MyTimer();
this.TextChanged += (s, ea) =>
{
if (timer.IsActive)
{
timer.Reset();
}
else
{
timer.WaitTime.Miliseconds = 500;
timer.Start();
timer.Completed += (a) =>
{
int i = 0;
Timer tm = new Timer();
tm.Interval = 1;
tm.Tick += (sa, aea) =>
{
i++;
this.ForeColor = Color.FromArgb(i, Color.Black);
this.BackColor = Color.FromArgb(i, Color.White);
this.Invalidate();
if (i == 255)
{
tm.Stop();
}
};
tm.Start();
};
}
};
}
This is what I'm using to fade out labels:
label1.Text = "I'm fading out now";
label1.ForeColor = Color.Black;
timer1.Start();
private void timer1_Tick(object sender, EventArgs e)
{
int fadingSpeed = 3;
label1.ForeColor = Color.FromArgb(label1.ForeColor.R + fadingSpeed, label1.ForeColor.G + fadingSpeed, label1.ForeColor.B + fadingSpeed);
if (label1.ForeColor.R >= this.BackColor.R)
{
timer1.Stop();
label1.ForeColor = this.BackColor;
}
}
Maybe not the best solution but I'm still a beginner so this is what I can contribute with. I put timer1.Interval
at minimum and played with fadingSpeed
until it looked good.
