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:
public class WindowBehaviorHelper { private const int WM_NCHITTEST = 0x0084; //测试消息 private const int WM_GETMINMAXINFO = 0x0024; //大小变化 private Window WindowTarget; //目标窗口 private int WidthCorner = 3; //拐角宽度 private int ThicknessTransparentBorder = 5; //阴影宽度 private int ThicknessBorder = 4; //边框宽度 private Point PointMouse = new Point(); //鼠标坐标 public enum HitTest : int //测试句柄 { #region 测试句柄 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 #endregion } //构造函数 public WindowBehaviorHelper(Window window) { this .WindowTarget = window;
