This is a great work for computer vision. Thanks for your code. It failed when i compiled this code . The error info : 1>DropGraphicsView.obj : error LNK2019: unresolved external symbol "public: __cdecl QtNodes::CreateCommand::CreateCommand(class QtNodes::BasicGraphicsScene *,class QString,class QPointF const &)" (??0CreateCommand@QtNodes@@QEAA@PEAVBasicGraphicsScene@1@VQString@@AEBVQPointF@@@Z) referenced in function "public: void __cdecl DropGraphicsView::placeNodeInScene(class QString const &,class QPoint const &)" (?placeNodeInScene@DropGraphicsView@@QEAAXAEBVQString@@AEBVQPoint@@@Z) 1>ComputerVisionBlueprint-main\build\Debug\ComputerVisionBlueprint.exe : fatal error LNK1120: 1 unresolved externals

maybe this is a dynamic dll problem . How can i fix it ?

fix UndoCommands.hpp line to this class NODE_EDITOR_PUBLIC CreateCommand : public QUndoCommand , it worked.

So the error was in the QtNodes library when compiling on windows?

yes, QtNodes link error . CreateCommand was not in QtNodes dll.
