wpf 右下角弹出窗

原文:wpf 右下角弹出窗

自己写的wpf 弹出框，欢迎拍砖，动画都写在了后台代码，前台代码不太重要，用了一下iconfont，具体样式我就不贴出来了，本次主要是后台代码的动画

需要有父级窗口才可以使用。

前台代码：

<Window x:Class="V2VReporter.Views.SystemViews.MsgPopup"

            <Grid Grid.Row="0" Background="{StaticResource MainGreen}">
                <Grid.ColumnDefinitions>

                    <ColumnDefinition Width="*"></ColumnDefinition>
                </Grid.ColumnDefinitions>
                <StackPanel Grid.Column="0" Orientation="Horizontal">
                    <TextBlock Text="" Style="{StaticResource IconFont}" VerticalAlignment="Center" FontSize="18" Foreground="AliceBlue" Margin="5,0,0,0"></TextBlock>
                    <TextBlock Text="系统消息" Foreground="AliceBlue" FontSize="15" VerticalAlignment="Center" Margin="2,0,0,0" ></TextBlock>
                </StackPanel>
                <StackPanel Grid.Column="1" HorizontalAlignment="Right">
                    <controls:IconButton Style="{StaticResource TitleCloseBtn}" Margin="0,5,2,0" Click="ButtonBase_OnClick"></controls:IconButton>
                </StackPanel>
            </Grid>
        </Grid>
    </Border>
</Window>

        }

        private void initedCloseStory()
        {
            close.From = 1;

            if (!close_flg)
            {

                {
                    close_flg = true;
                    this.Close();
                };
                sb_close.Begin();
                e.Cancel = true;
            }
            else
            {
                e.Cancel = false;
            }
        }

        private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
        {
            this.Close();
        }
    }
}

直接用的话会运行不起来，主要看后台动画代码和逻辑
