8.取色器的实现 var point = CursorPointManager.GetCursorPosition(); Root.CurrentColor = ColorPickerManager.GetColor(point.X, point.Y); 讲一个关键点:形状要可擦除,必须要转换一下 Geometry = Geometry.GetWidenedPathGeometry(aPen); 今天实在有点懒得搞,就这样吧。
首先要获取到当前鼠标位置处的ListViewItem的序号Index,采取的方法时查看当前鼠标的位置是否在ListView的某一个Item的范围之内,这里使用了VisualTreeHelper.GetDescendantBounds这个方法来获取元素的边界位置然后再判断当前鼠标位置是否位于此边界之内,通过这种方式来获取当前拖动的Index值。 void listView_PreviewMouseLeftButtonD...

然后我们来看看DisplayResizeCursor事件,它主要是用来改变鼠标形状,当鼠标达到一定区域,则显示拖拉的鼠标形状(<->): 其计算方式,请参看下图: privatevoidDisplayResizeCursor(objectsender, MouseEventArgs e) { Border clickBorder= senderasBorder; Point pos= Mouse.GetPosition(this);doublex =pos.X;doubley =pos...
pos= e.GetPosition(null); } }voidElement_MouseLeftButtonDown(objectsender, MouseButtonEventArgs e) { FrameworkElement fEle= senderasFrameworkElement; isDragDropInEffect=true; pos= e.GetPosition(null); fEle.CaptureMouse(); fEle.Cursor=Cursors.Hand; ...
pos = e.GetPosition(null); fEle.CaptureMouse(); fEle.Cursor = Cursors.Hand; } void Element_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { if (isDragDropInEffect) { FrameworkElement ele = sender as FrameworkElement; isDragDropInEffect = false; ...
however neither of these events gives us access to the mouse or cursor position during the drag operation :( ... We can however tap into the Dragover event; DragOverEventArgs has a GetPosition ( ) method that does the trick... DragOver however is fired in the target, not the source....
