我想在按下按钮时为我的按钮应用动画。在WPF中,我可以使用带有触发器的Storyboard
来创建动画。以下是一个例子:
<Storyboard x:Key="AniOpacityDelay">
<DoubleAnimation
Storyboard.TargetName="background"
Storyboard.TargetProperty="Opacity"
AutoReverse="True"
To="0.65"
Duration="0:0:0.2"/>
</Storyboard>
并且:
<ColorAnimationUsingKeyFrames
Storyboard.TargetName="Itemcont"
Storyboard.TargetProperty="(TextElement.Foreground).(SolidColorBrush.Color)">
<EasingColorKeyFrame KeyTime="0" Value="#EEEEEE"/>
</ColorAnimationUsingKeyFrames>
Windows Forms没有Storyboard
和触发器。那么如何在Windows Forms中实现平滑的动画效果呢?
以下是我在Windows Forms中的代码:
void DelayTime()
{
timer = new Timer();
timer.Interval = (int)System.TimeSpan.FromSeconds(this.DelayTime).TotalMilliseconds;
timer.Tick += (s, es) =>
{
this.mouseover = false;
this.Cursor = Cursors.Hand;
this.Enabled = true;
};
timer.Start();
}
protected override void OnMouseDown(MouseEventArgs mevent)
{
base.OnMouseDown(mevent);
mouseover = true;
this.Enabled = false;
DelayTime();
}
protected override void OnPaint(PaintEventArgs e)
{
Color bg = this._Background;
bg = mouseover ? this._HoverColor : this._Background;
e.Graphics.FillRectangle(new SolidBrush(bg), this.ClientRectangle);
}
