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
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中获取TreeView以及ListView获取其本身滚动条的方法,可实现自行调节scoll滚动的位置(可相应获取任何控件中的内部滚动条) 对于TreeView而言: TreeViewAutomationPeer lvap = new TreeViewAutomationPeer(treeView); var svap = lvap.GetPattern(PatternInterface.Scroll) as ScrollViewerAutomationPeer; var scroll
final int[] location = new int[2]; view.getLocationOnScreen(location); final int[] location = new int[2]; view.getLocationOnScreen(location); 这样就可以得到该视图在全局坐标系中的x,y值,(注意这个值是要从屏幕顶端算起,也就是索包括了通知栏的高度)//获取在当前屏幕内的绝对坐标 location[0] x坐标 location[1] y坐标 locatio
