解决Nodify框架因自带放大缩小、平移功能导致拖拽添加的控件无法准确在鼠标放下的位置显示控件

ViewModel中写具体关键的几段代码：

var editor = sender as NodifyEditor;              Point p = e.GetPosition(editor);//放大缩小比例double scale = editor.ViewportZoom;//经过放大缩小、平移后获得坐标点位置p = new Point(Math.Round((p.X - editor.ViewportTransform.Value.OffsetX) / scale,0), Math.Round((p.Y - editor.ViewportTransform.Value.OffsetY) / scale,0));

详细代码如下

第八节：Nodify 编辑器属性-CSDN博客

里面有编辑器的一些简介

CustomInterfaceViewModel.cs

//可通过拖拽复制控件
public void CtlList_PreviewMouseMove(object sender, MouseEventArgs e)
{if (ThumbSelectedItem != null && e.LeftButton == MouseButtonState.Pressed){DragDrop.DoDragDrop((DependencyObject)sender, ThumbSelectedItem, DragDropEffects.Copy);}
}//nodify 放大缩小、平移后鼠标放在哪个位置  控件就显示在哪个位置
//最重要的就是方法内前四句代码
//p = new Point(Math.Round((p.X - editor.ViewportTransform.Value.OffsetX) / scale,0), Math.Round((p.Y - editor.ViewportTransform.Value.OffsetY) / scale,0));public void nodify_Drop(object sender, DragEventArgs e)
{var editor = sender as NodifyEditor;              Point p = e.GetPosition(editor);double scale = editor.ViewportZoom;p = new Point(Math.Round((p.X - editor.ViewportTransform.Value.OffsetX) / scale,0), Math.Round((p.Y - editor.ViewportTransform.Value.OffsetY) / scale,0));if (ThumbSelectedItem.TypeName == "Button"){States.Add(new CustomViewModel(){Name = "New Button",IsRenaming = true,Location = p,ActionReference = Blackboard.Actions.Count > 0 ? Blackboard.Actions[0] : null,TargetType = ThumbSelectedItem.TypeName});}else if (ThumbSelectedItem.TypeName == "TextBox"){States.Add(new CustomViewModel{Code = GenerateUniqueRandomCode(1, 100),Name = "New TextBox",IsRenaming = true,Location = p,TargetType = "TextBox"});}else{States.Add(new CustomViewModel{Name = "New TextBlock",IsRenaming = true,Location = p,TargetType = "TextBlock"});}e.Handled = true;}
