在WPF中，经常需要对窗口进行设置，下面讲讲常用的几个设置。

窗口样式

1、无边框窗口

无边框透明窗体 设置

WindowStyle="None"--无边框，如果需要其它按钮，如缩小、放大、收缩、关闭按钮，可以自定义

AllowsTransparency="True"--只有设置了AllowsTransparency，才有1、窗体真正的隐藏边框2、背景透明有效

Background="Transparent"

窗口阴影设置

可以用Border的CornerRadius设置窗口四周圆角

设置窗口阴影--值得一提的是，如果直接用Window.Effect,效果会影响CornerRadius设置的圆角效果。

<Window.Effect>

<DropShadowEffect BlurRadius="30" Color="Gray" ShadowDepth="0" RenderingBias="Quality" ></DropShadowEffect>

</Window.Effect>

举例：

2、窗口按钮

当我们设置无边窗口时，也即是需要重新设置一套窗口的操作按钮。

按钮，可以用修改Button的Background或者修改Template,往其中设置图标或者直接用Path、Border、Rectangle等基础元素绘制。

然后添加简单的动画Animation

1) 方法1.下面是自定义的按钮Style，往其中传入图标路径即可

2）方法2.直接用基础元素绘制

Path，通过Path来画线。当然一般水平、竖直也是可以用Rectangle/Border之类的替代

一些简单的线条图标用Path来做，还是很方便的。

 

3、窗口 resize 鼠标自由改变窗口大小 （转）

覆写一个OnSourceInitialized方法，在其中添加一个委托

//重写        protected override void OnSourceInitialized(EventArgs e)        {            base.OnSourceInitialized(e);            HwndSource hwndSource = PresentationSource.FromVisual(this) as HwndSource;            if (hwndSource != null)            {                hwndSource.AddHook(new HwndSourceHook(WndProc));            }        }        private const int WM_NCHITTEST = 0x0084;        private Point mousePoint = new Point(); //鼠标坐标        private const int ResizeBorderAGWidth = 12;//转角宽度         private const int ResizeBorderThickness = 4;//边框宽度        /// 
        /// 委托方法        /// 
        ///         ///         ///         ///         ///         /// 
              protected virtual IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)        {            switch (msg)            {                case WM_NCHITTEST:                    mousePoint.X = (lParam.ToInt32() & 0xFFFF);                    mousePoint.Y = (lParam.ToInt32() >> 16);                    // 窗口左上角                    if (mousePoint.Y - Top <= ResizeBorderAGWidth && mousePoint.X - Left <= ResizeBorderAGWidth)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTTOPLEFT);                    }                    // 窗口左下角　　                    else if (ActualHeight + Top - mousePoint.Y <= ResizeBorderAGWidth && mousePoint.X - Left <= ResizeBorderAGWidth)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTBOTTOMLEFT);                    }                    // 窗口右上角                    else if (mousePoint.Y - Top <= ResizeBorderAGWidth && ActualWidth + Left - mousePoint.X <= ResizeBorderAGWidth)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTTOPRIGHT);                    }                    // 窗口右下角                    else if (ActualWidth + Left - mousePoint.X <= ResizeBorderAGWidth && ActualHeight + Top - mousePoint.Y <= ResizeBorderAGWidth)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTBOTTOMRIGHT);                    }                    // 窗口左侧                    else if (mousePoint.X - Left <= ResizeBorderThickness)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTLEFT);                    }                    // 窗口右侧                    else if (ActualWidth + Left - mousePoint.X <= ResizeBorderThickness)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTRIGHT);                    }                    // 窗口上方                    else if (mousePoint.Y - Top <= ResizeBorderThickness)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTTOP);                    }                    // 窗口下方                    else if (ActualHeight + Top - mousePoint.Y <= ResizeBorderThickness)                    {                        handled = true;                        return new IntPtr((int)HitTest.HTBOTTOM);                    }                    else // 窗口移动                    {                        //handled = true;                        //return new IntPtr((int)HitTest.HTCAPTION);                        return IntPtr.Zero;                    }            }            return IntPtr.Zero;        }

用到的枚举列表类：

public enum HitTest : int    {        HTERROR = -2,        HTTRANSPARENT = -1,        HTNOWHERE = 0,        HTCLIENT = 1,        HTCAPTION = 2,        HTSYSMENU = 3,        HTGROWBOX = 4,        HTSIZE = HTGROWBOX,        HTMENU = 5,        HTHSCROLL = 6,        HTVSCROLL = 7,        HTMINBUTTON = 8,        HTMAXBUTTON = 9,        HTLEFT = 10,        HTRIGHT = 11,        HTTOP = 12,        HTTOPLEFT = 13,        HTTOPRIGHT = 14,        HTBOTTOM = 15,        HTBOTTOMLEFT = 16,        HTBOTTOMRIGHT = 17,        HTBORDER = 18,        HTREDUCE = HTMINBUTTON,        HTZOOM = HTMAXBUTTON,        HTSIZEFIRST = HTLEFT,        HTSIZELAST = HTBOTTOMRIGHT,        HTOBJECT = 19,        HTCLOSE = 20,        HTHELP = 21,    }

  

窗口拖动

1、在界面上对布局元素如Grid,添加委托事件： MouseLeftButtonDown="UIElement_OnMouseLeftButtonDown"

2、委托方法中处理一下就行了：

private void UIElement_OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)        {            if (e.ButtonState==MouseButtonState.Pressed) { this.DragMove(); } }
