WPF绘图和动画-VisualBrush实例
XAML代码：
<Window x:Class="VisualBrush实例.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:VisualBrush实例"
mc:Ignorable="d"
Title="MainWindow" Height="300" Width="400">
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="160"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="160"/>
</Grid.ColumnDefinitions>
<StackPanel x:Name="StackPanelLeft" Background="White">
<Button x:Name="RealButton" Content="OK" Height="40"/>
</StackPanel>
<Button Content=">>>" Grid.Column="1" Margin="5,0" Click="CloneVisual"/>
<StackPanel x:Name="StackPanelRight" Background="White" Grid.Column="2"/>
</Grid>
</Window>
C#代码 ：
using System.Windows;
using System.Windows.Media;
using System.Windows.Shapes;
namespace VisualBrush实例
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private double _opacity =
1.0;
private void CloneVisual(
object sender, RoutedEventArgs e)
{
var vBrush=
new VisualBrush(RealButton);
var rect =
new Rectangle
{
Width = RealButton.ActualWidth,
Height = RealButton.ActualHeight,
Fill = vBrush,
Opacity = _opacity
};
_opacity -=
0.2;
StackPanelRight.Children.Add(rect);
}
}
}
