在WinForm中,获得句柄是一件很容易的事情,This.Handle或者Control.Handle就可以,最近在WPF的开发中发现找不到这个属性,一番查找资料后找到了两种方式. 1,使用WindowInteropHelper类可以获得Window的句柄,但这种方法有个局限性,它只接受类型为Window的参数,换句话说就是这种方法只能获得Window的句柄. public IntPtr Handle { get { IntPtr handle = new WindowInteropHelper
DG是控件名称public T GetVisualChild<T>(DependencyObject parent, Func<T, bool> predicate) where T : Visual{int numVisuals = VisualTreeHelper.GetChildrenCount(parent);for (int i = 0; i < numVisuals; i++){DependencyObject v = (DependencyObject)Visu
//获取内部 ScrollViewer方法 public static T FindVisualChild<T>(DependencyObject obj) where T : DependencyObject { if (obj != null) { for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
如果布局在Grid中: 方法一: //_stackPanel为子元素,_grid为父元素 Point point = _stackPanel.TranslatePoint(new Point(0, 0), (UIElement)_grid); 方法二: //_stackPanel为子元素,_grid为父元素 GeneralTransform generalTransform = _stackPanel.TransformToAncestor(_grid); Point point = gener
原文:WPF 获取鼠标屏幕位置.窗口位置.控件位置 public struct POINT { public int X; public int Y; public POINT(int x, int y) { this.X = x; this.Y = y; } } [DllImport("user32.dll")] public static extern bool GetCursorPos(out POINT lpPoint); //e.GetPosition(this); //(e
