    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:
