仿照网上的一个代码写的,地址找不到了。

将窗体,控件什么的都封装到一个类库里面了,方便以后使用。

界面效果:

窗体模板,主要是实现一个无边框窗体,并添加阴影效果。

    <Style TargetType="DazzleWPF:DazzleWindow">
        <Setter Property="AllowsTransparency" Value="true"/>
        <Setter Property="Background" Value="Transparent"/>
        <!--<Setter Property="ResizeMode" Value="CanResizeWithGrip"/>-->
        <Setter Property="WindowStyle" Value="None"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="DazzleWPF:DazzleWindow">
                    <Grid Margin="5">
                        <Rectangle Fill="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"    >
                            <Rectangle.Effect>
                                <DropShadowEffect BlurRadius="10" ShadowDepth="0"/>
                            </Rectangle.Effect>
                        </Rectangle>
                        <Border Background="{TemplateBinding Background}"    
                        BorderBrush="{TemplateBinding BorderBrush}"    
                        BorderThickness="{TemplateBinding BorderThickness}"    
                        Padding="{TemplateBinding Margin}"    
                        SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}">
                            <ContentPresenter />
                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

  窗体类,代码也很简单,调用一下类WindowBehaviorHelper 的方法,实现缩放操作的修复,避免最大化覆盖任务栏等。

  再添加一下鼠标左键按下的拖动支持。

  就OK了。

    public class DazzleWindow : Window
    {
        public DazzleWindow()
        {
            this.DefaultStyleKey = typeof(DazzleWindow);

            //缩放,最大化修复
            WindowBehaviorHelper wh = new WindowBehaviorHelper(this);
            wh.RepairBehavior();

            this.MouseLeftButtonDown += new System.Windows.Input.MouseButtonEventHandler(DazzleWindow_MouseLeftButtonDown);
        }

        void DazzleWindow_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
        {
            this.DragMove(); 
        }
    }

  窗体行为修复,主要代码来了:
